Describe the bug
Virtual Trading not work for me
Log: "rationale": "Grid NOOP — reasons: BTC/USDT: missing or invalid price (no snapshot price keys present). params(source=LLM, step_pct=0.0010, max_steps=3, base_fraction=0.0800, zone_pct=[-0.1000, +0.1000]); advisor_rationale=No new market metrics (volatility, liquidity, funding rate, open interest) were provided to justify a regime shift; thus, parameters remain anchored to previous settings. The current grid_step_pct (0.001) and grid_max_steps (3) are appropriate for a major pair like BTC/USDT under typical conditions. Portfolio equity ($10k), buying power ($20k), and cap_factor (1.5) support the existing base_fraction (0.08) without exceeding risk or leverage limits. In absence of signals indicating elevated volatility, high funding, or OI changes, conservative continuity is preferred.",
