CHANGELOG for Binance's API (2024-02-28)

2024-02-28

This will take effect on March 5, 2024.

Simple Binary Encoding (SBE) will be added to the live exchange, both for the Rest API and WebSocket API.

For more information on SBE, please refer to the FAQ

2024-02-08

The SPOT WebSocket API can now support SBE on SPOT Testnet.

The SBE schema has been updated with WebSocket API metadata without incrementing either schemaId or version.

Users using SBE only on the REST API may continue to use the SBE schema with git commit hash 128b94b2591944a536ae427626b795000100cf1d or update to the newly-published SBE schema.

Users who want to use SBE on the WebSocket API must use the newly-published SBE schema.

The FAQ for SBE has been updated.

2023-12-08

Simple Binary Encoding (SBE) has been added to SPOT Testnet.

This will be added to the live exchange at a later date.

For more information on what SBE is, please refer to the FAQ

2023-12-04

Notice: The changes below are being rolled out gradually, and will take approximately a week to complete.

General Changes:

  • Error message Precision is over the maximum defined for this asset. has been changed to Parameter '%s' has too much precision.
    • This error message is returned when a parameter has more precision than allowed: e.g. if base asset precision is 6 and quantity=0.1234567 then this error message will appear.
    • This affects all requests with the following parameters:
      • quantity
      • quoteOrderQty
      • icebergQty
      • limitIcebergQty
      • stopIcebergQty
      • price
      • stopPrice
      • stopLimitPrice
  • Requests for open OCO now correctly return results in ascending order. This affects the following requests:
    • REST API: GET /api/v3/openOrderList
    • WebSocket API: openOrderList.status
  • Requests for all OCO now correctly return results in ascending order when startTime or fromId are specified. This affects the following requests:
    • REST API: GET /api/v3/allOrderList
    • WebSocket API: allOrderLists
  • Fixed a bug where order query requests would incorrectly return -2026 ORDER_ARCHIVED error for newly placed orders.
    • REST API: GET /api/v3/order
    • WebSocket API: order.status

REST API

  • New endpoint GET /api/v3/account/commission
  • New endpoint GET /api/v3/ticker/tradingDay
  • GET /api/v3/avgPrice response has a new field closeTime, indicating the last trade time.
  • GET /api/v3/klines and /api/v3/uiKlines have a new optional parameter timeZone.
  • POST /api/v3/order/test and POST /api/v3/sor/order/test have a new optional parameter computeCommissionRates.
  • Changes regarding invalid endpoints being sent:
    • Previously, if you query an non-existing endpoint (e.g. curl -X GET "https://api.binance.com/api/v3/exchangie) you would get a HTTP 404 code with the response <html><body><h2>404 Not found</h2></body></html>
    • From now on the HTML response will only appear if the Accept request header has text/html for this situation. The HTTP code will remain the same.

WebSocket API

  • New request account.commission
  • New requests to allow session authentication: (Note that these requests can only be used with Ed25519 keys.)
    • session.logon
    • session.logout
    • session.status
  • New request ticker.tradingDay
  • avgPrice response has a new field closeTime, indicating the last trade time.
  • klines and uiKlines have a new optional parameter timeZone.
  • order.test and sor.order.test have a new optional parameter computeCommissionRates.
  • Fixed a bug where unsolicited pongs sent before the ping would cause disconnection.

WebSocket Streams

  • New stream <symbol>@avgPrice
  • id now supports the same values as used for id in the WebSocket API:
    • 64-bit signed integers (previously this was unsigned)
    • Alphanumeric strings, max of 36 in length
    • null
  • Fixed a bug where unsolicited pongs sent before the ping would cause disconnection.

User Data Streams

  • When an event of type executionReport has an execution type (x) of TRADE_PREVENTION, fields l, L and Y will now always be 0. New fields pl, pL and pY will describe the prevented execution quantity, prevented execution price, and prevented execution notional instead. These new fields show the values of what would l, L and Y have been if the taker order didn't have self-trade prevention enabled.

The following will take effect approximately a week after the release date:

  • Symbol Permissions will only affect order placement, not cancellation.
    • permissions still apply to Cancel-Replace orders (i.e. The cancellation won't be allowed if your account does have the permission to place an order using this request.)

2023-10-19

Effective on 2023-10-19 00:00 UTC

  • The request weights of the following requests have been increased:
REST API WebSocket API Condition Previous Request Weight New Request Weight
GET /api/v3/trades trades.recent N/A 2 10
GET /api/v3/depth depth Limit 1-100 2 5
Limit 101-500 10 25
Limit 501-1000 20 50
Limit 1001-5000 100 250

2023-10-03

  • Order decrement feature went live at 06:15 UTC.
  • For more information on this feature, please refer to our FAQ

2023-08-25

  • For WebSocket API, removed RAW REQUESTS rate limit in exchangeInfo, replaced it with CONNECTIONS rate limit, which is the limit for new Websocket connections.

The following changes will be effective from 2023-08-25 at UTC 00:00.

  • The CONNECTIONS rate limit for WebSocket API has been adjusted to 300 every 5 minutes.
  • The REQUEST_WEIGHT rate limit for both REST and WebSocket API has been adjusted to 6,000 every minute.
  • The RAW_REQUESTS rate limit for REST API has been adjusted to 61,000 every 5 minutes.
  • Previously, connecting to WebSocket API used to cost 1 weight. The cost is now 2.
  • The weights to the following requests for both REST API and WebSocket API have been adjusted.

2023-07-11

Notice: The change below are being rolled out, and will take approximately a week to complete.

General Changes:

  • Changes to error messages:
    • Previously, when duplicate symbols were passed to requests that do not allow it, the error would be "Mandatory parameter symbols was not sent, was empty/null, or malformed."
    • Now, the error message is "Symbol is present multiple times in the list", with a new error code -1151
    • This affects the following requests:
      • GET /api/v3/exchangeInfo
      • GET /api/v3/ticker/24hr
      • GET /api/v3/ticker/price
      • GET/api/v3/ticker/bookTicker

Rest API

  • Changes to GET /api/v3/account:
    • New field preventSor will appear in the response.
    • New field uid that shows the User Id/Account will appear in the response.
  • Changes to GET /api/v3/historicalTrades:
    • Changed security type from MARKET_DATA to NONE.
    • This means that the X-MBX-APIKEY header is no longer necessary and is now ignored.

Websocket API

  • Changes to account.status:
    • New field preventSor will appear in the response.
    • New field uid that shows the User Id/Account will appear in the response.
  • Changes to trades.historical:

    • This means that the apiKey parameter is no longer necessary and is now ignored.

The following changes will take effect approximately a week from the release date::

  • Fixed multiple bugs with orders that use type=MARKET and quoteOrderQty, also known as “reverse market orders”:
    • Reverse market orders are no longer partially filled, or filled for zero or negative quantity under extreme market conditions.
    • MARKET_LOT_SIZE filter now correctly rejects reverse market orders that go over the symbol's maxQty.
  • Fixed a bug where OCO orders using trailingDelta could have an incorrect trailingTime value after either leg of the OCO is touched.

2023-05-26

Notice: The change below are being rolled out, and will take approximately a week to complete.

2023-05-24

  • The previous market data URLs have been deprecated. Please update your code immediately to prevent interruption of our services.
    • API Market data from data.binance.com can now be accessed from data-api.binance.vision.
    • Websocket Market Data from data-stream.binance.com can now be accessed from data-stream.binance.vision.

2023-03-13

Notice: All changes are being rolled out gradually to all our servers, and may take a week to complete.

GENERAL CHANGES

  • The error messages for certain issues have been improved for easier troubleshooting.
Situation Old Error Message New Error Message
An account cannot place or cancel an order, due to trading ability disabled. This action is disabled on this account. This account may not place or cancel orders.
When the permissions configured on the symbol do not match the permissions on the account. This symbol is not permitted for this account.
When the account tries to place an order on a symbol it has no permissions for. This symbol is restricted for this account.
Placing an order when symbol is not TRADING. Unsupported order combination. This order type is not possible in this trading phase.
Placing an order with timeinForce=IOC or FOK on a trading phase that does not support it. Limit orders require GTC for this phase.
  • Fixed error message for querying archived orders:
    • Previously, if an archived order (i.e. order with status CANCELED or EXPIRED where executedQty == 0 that occurred more than 90 days in the past.) is queried, the error message would be:
    {
    "code": -2013,
    "msg": "Order does not exist." 
}
    • Now, the error message is:
    {
    "code": -2026,
    "msg": "Order was canceled or expired with no executed qty over 90 days ago and has been archived." 
}
  • Behavior for API requests with startTime and endTime:
    • Previously some requests failed if the startTime == endTime.
    • Now, all API requests that accept startTime and endTime allow the parameters to be equal. This applies to the following requests:
      • Rest API
        • GET /api/v3/aggTrades
        • GET /api/v3/klines
        • GET /api/v3/allOrderList
        • GET /api/v3/allOrders
        • GET /api/v3/myTrades
      • Websocket API
        • trades.aggregate
        • klines
        • allOrderList
        • allOrders
        • myTrades
  • Users connected to the websocket API will now be disconnected if their IP is banned due to violation of the IP rate limits (status 418).

The following changes will take effect approximately a week from the release date, but the rest of the documentation has been updated to reflect the future changes:

  • Changes to Filter Evaluation:
    • Previous behavior: LOT_SIZE and MARKET_LOT_SIZE required that (quantity - minQty) % stepSize == 0.
    • New behavior: This has now been changed to (quantity % stepSize) == 0.
  • Bug fix with reverse MARKET orders (i.e., MARKET using quoteOrderQty):
    • Previous behavior: Reverse market orders would always have the status FILLED even if the order did not fully fill due to low liquidity.
    • New behavior: If the reverse market order did not fully fill due to low liquidity the order status will be EXPIRED, and FILLED only if the order was completely filled.

REST API

  • Changes to DELETE /api/v3/order and POST /api/v3/order/cancelReplace:
    • A new optional parameter cancelRestrictions that determines whether the cancel will succeed if the order status is NEW or PARTIALLY_FILLED.
    • If the order cancellation fails due to cancelRestrictions, the error will be:
    {
    "code": -2011, 
    "msg": "Order was not canceled due to cancel restrictions."
}

WEBSOCKET API

  • Changes to order.cancel and order.cancelReplace:
    • A new optional parameter cancelRestrictions that determines whether the cancel will succeed if the order status is NEW or PARTIALLY_FILLED.
    • If the order cancellation fails due to cancelRestrictions, the error will be:
    {
    "code": -2011, 
    "msg": "Order was not canceled due to cancel restrictions."
}

2023-02-17

Changes to Websocket Limits

The WS-API and Websocket Stream now only allows 300 connections requests every 5 minutes.

This limit is per IP address.

Please be careful when trying to open multiple connections or reconnecting to the Websocket API.

2023-01-26

As per the announcement, Self Trade Prevention will be enabled at 2023-01-26 08:00 UTC.

Please refer to GET /api/v3/exchangeInfo from the Rest API or exchangeInfo from the Websocket API on the default and allowed modes.

2023-01-23

New API cluster has been added. Note that all endpoints are functionally equal, but may vary in performance.

RELEASE DATE TBD

New Feature: Self-Trade Prevention (aka STP) will be added to the system at a later date. This will prevent orders from matching with orders from the same account, or accounts under the same tradeGroupId.

Please refer to GET /api/v3/exchangeInfo from the Rest API or exchangeInfo from the Websocket API on the status.

"defaultSelfTradePreventionMode": "NONE",   //If selfTradePreventionMode not provided, this will be the value passed to the engine
"allowedSelfTradePreventionModes": [        //What the allowed modes of selfTradePrevention are
    "NONE",
    "EXPIRE_TAKER",
    "EXPIRE_BOTH",
    "EXPIRE_MAKER"
]

Additional details on the functionality of STP is explained in the STP FAQ document.

REST API

  • New order status: EXPIRED_IN_MATCH - This means that the order expired due to STP being triggered.
  • New endpoint:
    • GET /api/v3/myPreventedMatches - This queries the orders that expired due to STP being triggered.
  • New optional parameter selfTradePreventionMode has been added to the following endpoints:
    • POST /api/v3/order
    • POST /api/v3/order/oco
    • POST /api/v3/cancelReplace
  • New responses that will appear for all order placement endpoints if there was a prevented match (i.e. if an order could have matched with an order of the same account, or the accounts are in the same tradeGroupId):
    • tradeGroupId - This will only appear if account is configured to a tradeGroupId and if there was a prevented match.
    • preventedQuantity - Only appears if there was a prevented match.
    • An array preventedMatches with the following fields:
      • preventedMatchId
      • makerOrderId
      • price
      • takerPreventedQuantity - This will only appear if selfTradePreventionMode set is EXPIRE_TAKER or EXPIRE_BOTH.
      • makerPreventedQuantity - This will only appear if selfTradePreventionMode set is EXPIRE_MAKER or EXPIRE_BOTH.
  • New fields preventedMatchId and preventedQuantity that can appear in the order query endpoints if the order had expired due to an STP trigger:
    • GET /api/v3/order
    • GET /api/v3/openOrders
    • GET /api/v3/allOrders

WEBSOCKET API

  • New order status: EXPIRED_IN_MATCH - This means that the order expired due to STP being triggered.
  • New optional parameter selfTradePreventionMode has been added to the following requests:
    • order.place
    • orderList.place
    • order.cancelReplace
  • New request: myPreventedMatches - This queries the orders that expired due to STP being triggered.
  • New responses that will appear for all order placement endpoints if there was a prevented match (i.e. if an order could have matched with an order of the same account, or the accounts are in the same tradeGroupId):
    • tradeGroupId - This will only appear if account is configured to a tradeGroupId and if there was a prevented match.
    • preventedQuantity - Only appears if there was a prevented match.
    • An array preventedMatches with the following fields:
      • preventedMatchId
      • makerOrderId
      • price
      • takerPreventedQuantity - This will only appear if selfTradePreventionMode set is EXPIRE_TAKER or EXPIRE_BOTH.
      • makerPreventedQuantity - This will only appear if selfTradePreventionMode set is EXPIRE_MAKER or EXPIRE_BOTH.
  • New fields preventedMatchId and preventedQuantity that can appear in the order query requests if the order had expired due to STP trigger:
    • order.status
    • openOrders.status
    • allOrders

USER DATA STREAM

2022-12-28

  • SPOT WebSocket API documentation has been updated to show how to sign a request using an RSA key.

2022-12-26

  • Spot WebSocket API is now available on the live exchange.
  • Spot Websocket API can be accessed through this URL: wss://ws-api.binance.com/ws-api/v3

2022-12-15

  • New RSA signature
    • Documentation has been updated to show how to create RSA keys.
    • For security reasons, we recommend to use RSA keys instead of HMAC keys when generating an API key.
    • We accept PKCS#8 (BEGIN PUBLIC KEY).
    • More details on how to upload your RSA public key will be added at a later date.
  • SPOT WebSocket API is now available on SPOT Testnet.
    • WebSocket API allows placing orders, canceling orders, etc. through a WebSocket connection.
    • WebSocket API is a separate service from WebSocket Market Data streams. I.e., placing orders and listening to market data requires two separate WebSocket connections.
    • WebSocket API is subject to the same Filter and Rate Limit rules as REST API.
    • WebSocket API and REST API are functionally equivalent: they provide the same features, accept the same parameters, return the same status and error codes.

WEBSOCKET API WILL BE AVAILABLE ON THE LIVE EXCHANGE AT A LATER DATE.

2022-12-13

REST API

Some error messages on error code -1003 have changed.

  • Previous error message: Too much request weight used; current limit is %s request weight per %s %s. Please use the websocket for live updates to avoid polling the API. has been updated to:
Too much request weight used; current limit is %s request weight per %s. Please use WebSocket Streams for live updates to avoid polling the API.
  • Previous error message Way too much request weight used; IP banned until %s. Please use the websocket for live updates to avoid bans. has been updated to:
Way too much request weight used; IP banned until %s. Please use WebSocket Streams for live updates to avoid bans.

2022-12-05

Notice: These changes are being rolled out gradually to all our servers, and will take approximately a week to complete.

WEBSOCKET

  • !bookTicker will be removed by December 7, 2022. Please use the Individual Book Ticker Streams instead (<symbol>@bookTicker).
    • Multiple <symbol>@bookTicker streams can be subscribed to over one connection. (E.g. wss://stream.binance.com:9443/stream?streams=btcusdt@bookTicker/bnbbtc@bookTicker)

REST API

  • New error code -1135
    • This error code will occur if a parameter requiring a JSON object is invalid.
  • New error code -1108
    • This error will occur if a value to a parameter being sent was too large, potentially causing overflow.
    • This error code can occur in the following endpoints:
      • POST /api/v3/order
      • POST /api/v3/order/cancelReplace
      • POST /api/v3/order/oco
  • Changes to GET /api/v3/aggTrades
    • Previous behavior: startTime and endTime had to be used in combination and could only be an hour apart.
    • New behavior: startTime and endTime can be used individually and the 1 hour limit has been removed.
      • When using startTime only, this will return trades from that time, up to the limit provided.
      • When using endTime only, this will return trades before that time, up to the limit provided.
      • If limit not provided, regardless of used in combination or sent individually, the endpoint will use the default limit.
  • Changes to GET /api/v3/myTrades

    • Fixed a bug where symbol + orderId combination would return all trades even if the number of trades went beyond the 500 default limit.

    • Previous behavior: The API would send specific error messages depending on the combination of parameters sent. E.g:

          {
        "code": -1106,
        "msg": "Parameter X was sent when not required."
    }

    • New behavior: If the combinations of optional parameters to the endpoint were not supported, then the endpoint will respond with the generic error:

          {
        "code": -1128,
        "msg": "Combination of optional parameters invalid."
    }

    • Added a new combination of supported parameters: symbol + orderId + fromId.

    • The following combinations of parameters were previously supported but no longer accepted, as these combinations were only taking fromId into consideration, ignoring startTime and endTime:

      • symbol + fromId + startTime
      • symbol + fromId + endTime
      • symbol + fromId + startTime + endTime

    • Thus, these are the supported combinations of parameters:

      • symbol
      • symbol + orderId
      • symbol + startTime
      • symbol + endTime
      • symbol + fromId
      • symbol + startTime + endTime
      • symbol+ orderId + fromId

Note: These new fields will appear approximately a week from the release date.

  • Changes to GET /api/v3/exchangeInfo
    • New fields defaultSelfTradePreventionMode and allowedSelfTradePreventionModes
  • Changes to the Order Placement Endpoints/Order Query/Order Cancellation Endpoints:
    • New field selfTradePreventionMode will appear in the response.
    • Affects the following endpoints:

Note that these are rolling changes, so it may take a few days for it to rollout to all our servers.

  • Changes to GET /api/v3/exchangeInfo
    • New optional parameter permissions added to display all symbols with the permissions matching the parameter provided. (eg.SPOT,MARGIN)
    • If not provided, the default value will be ["SPOT","MARGIN","LEVERAGED"].
      • This means the request GET /api/v3/exchangeInfo without any parameters will show all symbols that can be used for SPOT, MARGIN, and/or LEVERAGED trading.
      • To search for symbols that can be traded on other permissions (e.g. TRD_GRP_004, etc), then this needs to be searched for explicitly. (e.g.permissions=TRD_GRP_004)
    • Cannot be combined with symbol or symbols

2022-08-23

Note that these are rolling changes, so it may take a few days for it to rollout to all our servers.

  • Changes to GET /api/v3/ticker and GET /api/v3/ticker/24hr
    • New optional parameter type added
    • Supported values for parameter type are FULL and MINI

2022-08-08

REST API

  • Changes to POST /api/v3/order and POST /api/v3/order/cancelReplace
    • New optional fields strategyId and strategyType
      • strategyId is a parameter used to identify an order as part of a strategy.
      • strategyType is a parameter used to identify what strategy was running. (E.g. If all the orders are part of spot grid strategy, it can be set to strategyType=1000000)
        • Note that the minimum value allowed for strategyType is 1000000.
  • Changes to POST /api/v3/order/oco
    • New optional fields limitStrategyId, limitStrategyType, stopStrategyId, stopStrategyType
    • These are the strategy metadata parameters for both legs of the OCO orders.
    • limitStrategyType and stopStrategyType both cannot be less than 1000000.

2022-06-20

Changes to GET /api/v3/ticker

  • Weight has been reduced from 5 to 2 per symbol, regardless of windowSize.
  • The max number of symbols that can be processed in a request is 100.
    • If the number of symbols sent is more than 100, the error will be as follows:
    {
 "code": -1101,
 "msg": "Too many values sent for parameter 'symbols', maximum allowed up to 100."
}
  • The max Weight for this endpoint will cap at 100.
    • I.e. If the request has more than 50 symbols, the Weight will still be 100, regardless of windowSize.

2022-06-15

Note: The update is being rolled out over the next few days, so these changes may not be visible right away.

SPOT API

  • GET /api/v3/ticker added
    • Rolling window price change statistics based on windowSize provided.
    • Contrary to GET /api/v3/ticker/24hr the list of symbols cannot be omitted.
    • If windowSize not specified, the value will default to 1d.
    • Response is similar to GET /api/v3/ticker/24hr, minus the following fields: prevClosePrice, lastQty, bidPrice, bidQty, askPrice, askQty
  • GET /api/v3/exchangeInfo returns new field cancelReplaceAllowed in symbols list.
  • POST /api/v3/order/cancelReplace added
    • Cancels an existing order and places a new order on the same symbol.
    • The filters are evaluated before the cancel order is placed.
      • e.g. If the MAX_NUM_ORDERS filter is 10, and the total number of open orders on the account is also 10, when using POST /api/v3/order/cancelReplace both the cancel order placement and new order will fail because of the filter.
    • The change is being rolled out in the next few days, thus this feature will be enabled once the upgrade is completed.
  • New filter NOTIONAL has been added.
    • Defines the allowed notional value (price * quantity) based on a configured minNotional and maxNotional
  • New exchange filter EXCHANGE_MAX_NUM_ICEBERG_ORDERS has been added.
    • Defines the limit of open iceberg orders on an account

2022-05-23

  • Changes to Order Book Depth Levels

    • Quantities in the Depth levels were returning negative values in situations where they were exceeding the max value, resulting in an overflow.
    • Going forward depth levels will not overflow, but will be capped at the max value based on the precision of the base asset. This means that the depth level is at max value or more.
      • E.g. If the precision is 8, then the max value for quantity will be at 92,233,720,368.54775807.
    • When the fix has been applied, a change in the order book at the affected price level is required for the changes to be visible.

  • What does this affect?

    • SPOT API
      • GET /api/v3/depth
    • Websocket Streams
      • <symbol>@depth
      • <symbol>@depth@100ms
      • <symbol>@depth<levels>
      • <symbol>@depth<levels>@100ms

  • Updates to MAX_POSITION

    • If an order's quantity can cause the position to overflow, this will now fail the MAX_POSITION filter.

2022-05-17

  • Changes to GET api/v3/aggTrades
    • When providing startTime and endTime, the oldest items are returned.
  • Changed error messaging on GET /api/v3/myTrades where parameter symbol is not provided:
{
"code": -1102,
"msg": "Mandatory parameter 'symbol' was not sent, was empty/null, or malformed."
}
  • The following endpoints now support multi-symbol querying using the parameter symbols.
    • GET /api/v3/ticker/24hr
    • GET /api/v3/ticker/price
    • GET /api/v3/ticker/bookTicker
  • In the above, the request weight will depend on the number of symbols provided in symbols.
    Please refer to the table below:
Endpoint Number of Symbols Weight
GET /api/v3/ticker/price Any 2
GET /api/v3/ticker/bookTicker Any 2
GET /api/v3/ticker/24hr 1-20 1
GET /api/v3/ticker/24hr 21-100 20
GET /api/v3/ticker/24hr 101 or more 40

2022-04-13

REST API

  • Trailing Stops have been enabled.
    • This is a type of algo order where the activation is based on a percentage of a price change in the market using the new parameter trailingDelta.
    • This can only used with any of the following order types: STOP_LOSS, STOP_LOSS_LIMIT, TAKE_PROFIT, TAKE_PROFIT_LIMIT.
    • The trailingDelta parameter will be done in Basis Points or BIPS.
      • For example: a STOP_LOSS SELL order with a trailingDelta of 100 will trigger after a price decrease of 1% from the highest price after the order is placed. (100 / 10,000 => 0.01 => 1%)
    • When used in combination with OCO Orders, the trailingDelta will determine when the contingent leg of the OCO will trigger.
    • When trailingDelta is used in combination with stopPrice, once the stopPrice condition is met, the trailing stop starts tracking the price change from the stopPrice based on the trailingDelta provided.
    • When no stopPrice is sent, the trailing stop starts tracking the price changes from the last price based on the trailingDelta provided.
  • Changes to POST /api/v3/order
    • New optional field trailingDelta
  • Changes to POST /api/v3/order/test
    • New optional field trailingDelta
  • Changes to POST /api/v3/order/oco

    {
 "code": -1102,
 "msg": "Mandatory parameter 'symbol' was not sent, was empty/null, or malformed."
}
  • Fixed a typo with an error message when an account has disabled permissions (e.g. to withdraw, to trade, etc) 
    "This action is disabled on this account."
  • During a market data audit, we detected some issues with the Spot aggregate trade data.
    • Missing aggregate trades were recovered.
    • Duplicated records were marked invalid with the following values:
      • p = '0' // price

    • The limit value can be outside of the previous values (i.e. 5, 10, 20, 50, 100, 500, 1000,5000) and will return the correct limit. (i.e. if limit=3 then the response will be the top 3 bids and asks)
    • The limit still cannot exceed 5000. If the limit provided is greater than 5000, then the response will be truncated to 5000.
    • Due to the changes, these are the updated request weights based on the limit value provided:

Rest API

  • New order type: OCO ("One Cancels the Other")

    • An OCO has 2 orders: (also known as legs in financial terms)

      • STOP_LOSS or STOP_LOSS_LIMIT leg
      • LIMIT_MAKER leg

    • Price Restrictions:

      • SELL Orders : Limit Price > Last Price > Stop Price
      • BUY Orders : Limit Price < Last Price < Stop Price
      • As stated, the prices must "straddle" the last traded price on the symbol. EX: If the last price is 10:
        • A SELL OCO must have the limit price greater than 10, and the stop price less than 10.
        • A BUY OCO must have a limit price less than 10, and the stop price greater than 10.

    • Quantity Restrictions:

      • Both legs must have the same quantity.
      • ICEBERG quantities however, do not have to be the same.

    • Execution Order:

      • If the LIMIT_MAKER is touched, the limit maker leg will be executed first BEFORE canceling the Stop Loss Leg.
      • if the Market Price moves such that the STOP_LOSS or STOP_LOSS_LIMIT will trigger, the Limit Maker leg will be canceled BEFORE executing the STOP_LOSS Leg.

    • Canceling an OCO

      • Canceling either order leg will cancel the entire OCO.
      • The entire OCO can be canceled via the orderListId or the listClientOrderId.

    • New Enums for OCO:

      1. ListStatusType
        • RESPONSE - used when ListStatus is responding to a failed action. (either order list placement or cancellation)
        • EXEC_STARTED - used when an order list has been placed or there is an update to a list's status.
        • ALL_DONE - used when an order list has finished executing and is no longer active.
      2. ListOrderStatus
        • EXECUTING - used when an order list has been placed or there is an update to a list's status.
        • ALL_DONE - used when an order list has finished executing and is no longer active.
        • REJECT - used when ListStatus is responding to a failed action. (either order list placement or cancellation)
      3. ContingencyType
        • OCO - specifies the type of order list.

    • New Endpoints:

      • POST api/v3/order/oco
      • DELETE api/v3/orderList
      • GET api/v3/orderList

  • recvWindow cannot exceed 60000.

  • New intervalLetter values for headers:

    • SECOND => S
    • MINUTE => M
    • HOUR => H
    • DAY => D

  • New Headers X-MBX-USED-WEIGHT-(intervalNum)(intervalLetter) will give your current used request weight for the (intervalNum)(intervalLetter) rate limiter. For example, if there is a one minute request rate weight limiter set, you will get a X-MBX-USED-WEIGHT-1M header in the response. The legacy header X-MBX-USED-WEIGHT will still be returned and will represent the current used weight for the one minute request rate weight limit.

  • New Header X-MBX-ORDER-COUNT-(intervalNum)(intervalLetter)that is updated on any valid order placement and tracks your current order count for the interval; rejected/unsuccessful orders are not guaranteed to have X-MBX-ORDER-COUNT-** headers in the response.

    • Eg. X-MBX-ORDER-COUNT-1S for "orders per 1 second" and X-MBX-ORDER-COUNT-1D for orders per "one day"

  • GET api/v1/depth now supports limit 5000 and 10000; weights are 50 and 100 respectively.

  • GET api/v1/exchangeInfo has a new parameter ocoAllowed.

USER DATA STREAM

  • executionReport event now contains "g" which has the orderListId; it will be set to -1 for non-OCO orders.
  • New Event Type listStatus; listStatus is sent on an update to any OCO order.
  • New Event Type outboundAccountPosition; outboundAccountPosition is sent any time an account's balance changes and contains the assets that could have changed by the event that generated the balance change (a deposit, withdrawal, trade, order placement, or cancellation).

NEW ERRORS

  • -1131 BAD_RECV_WINDOW
    • recvWindow must be less than 60000
  • -1099 Not found, authenticated, or authorized

  • New filters: PERCENT_PRICE, MARKET_LOT_SIZE, MAX_NUM_ICEBERG_ORDERS.
  • Added RAW_REQUESTS rate limit. Limits based on the number of requests over X minutes regardless of weight.
  • /api/v3/ticker/price increased to weight of 2 for a no symbol query.
  • /api/v3/ticker/bookTicker increased weight of 2 for a no symbol query.
  • DELETE /api/v3/order will now return an execution report of the final state of the order.
  • MIN_NOTIONAL filter has two new parameters: applyToMarket (whether or not the filter is applied to MARKET orders) and avgPriceMins (the number of minutes over which the price averaged for the notional estimation).
  • intervalNum added to /api/v1/exchangeInfo limits. intervalNum describes the amount of the interval. For example: intervalNum 5, with interval minute, means "every 5 minutes".

Explanation for the average price calculation:

  1. (qty * price) of all trades / sum of qty of all trades over previous 5 minutes.

  2. If there is no trade in the last 5 minutes, it takes the first trade that happened outside of the 5min window. For example if the last trade was 20 minutes ago, that trade's price is the 5 min average.

  3. If there is no trade on the symbol, there is no average price and market orders cannot be placed. On a new symbol with applyToMarket enabled on the MIN_NOTIONAL filter, market orders cannot be placed until there is at least 1 trade.

  4. The current average price can be checked here: https://api.binance.com/api/v3/avgPrice?symbol=<symbol> For example: https://api.binance.com/api/v3/avgPrice?symbol=BNBUSDT

User data stream

Rest API

  • New filter: ICEBERG_PARTS
  • POST api/v3/order new defaults for newOrderRespType. ACK, RESULT, or FULL; MARKET and LIMIT order types default to FULL, all other orders default to ACK.
  • POST api/v3/order RESULT and FULL responses now have cummulativeQuoteQty
  • GET api/v3/openOrders with no symbol weight reduced to 40.
  • GET api/v3/ticker/24hr with no symbol weight reduced to 40.
  • Max amount of trades from GET /api/v1/trades increased to 1000.

  • Rest API Order lookups now return updateTime which represents the last time the order was updated; time is the order creation time.
  • Order lookup endpoints will now return cummulativeQuoteQty. If cummulativeQuoteQty is < 0, it means the data isn't available for this order at this time.
  • REQUESTS rate limit type changed to REQUEST_WEIGHT. This limit was always logically request weight and the previous name for it caused confusion.

User data stream

  • cummulativeQuoteQty field added to order responses and execution reports (as variable Z). Represents the cummulative amount of the quote that has been spent (with a BUY order) or received (with a SELL order). Historical orders will have a value < 0 in this field indicating the data is not available at this time. cummulativeQuoteQty divided by cummulativeQty will give the average price for an order.
  • O (order creation time) added to execution reports
