My Trading Bot Skipped 28 Trades Because I Ignored Volatility on a Tiny Real-Money Budget

说明与用途

由于预算误算和忽视波动性，交易机器人错过了28笔交易。通过基于波动性的仓位调整和现实预算重新编写逻辑，并加入自动检查与人工审核，恢复了正常运行。

问题

A trading bot failed to execute trades due to mis‑calculated budget constraints and ignored market volatility, causing 28 missed opportunities and 77% idle time.

结果

The bot now operates within a realistic budget, respects volatility differences, and avoids missed trades. Automated checks catch silent failures, while manual code reviews prevent accidental state loss.

工作流

• 1. Build a monitoring script (daily_check.py) to log bot activity each night.
• 2. Run the script to identify missed trades and budget exhaustion.
• 3. Analyze correlation and risk imbalance among symbols.
• 4. Rewrite position sizing to use volatility‑proportional slices and a realistic total cap.
• 5. Implement a security gate (security_gate.py) and manual review process for code changes.
• 6. Deploy updated bot logic (run.py) and re‑enable scheduler.
• 7. Continuously monitor with daily_check.py and review logs.

证据

The bot was trying to enter all four symbols at once because they are highly correlated. When SPY and QQQ signaled a buy, the $40 budget was gone.

I had to rewrite the entire sizing logic to fit into a much smaller shoebox.
