Next-day watchlist

Debrief agent architecture

The debrief agent aggregates output from the other agents. It references stored data from parts 1–4, pulling today's flow alerts (Part 2 data), current position Greeks/P&L (Part 3 data), earnings calendar updates (Part 4 data), and adding EOD VIX and market summary.

The debrief runs at 4:15 PM ET—15 minutes after the 4:00 PM market close, giving time for final prices to settle and for after-hours earnings to be noted. Here's the YAML config:

agents:
  eod-debrief:
    description: "End-of-day trading debrief with flow recap, P&L, and next-day watchlist"
    tools:
      - tradier-api

      polygon_token: "${POLYGON_API_KEY}"
      positions_yaml_path: "./positions.yaml"
      watchlist: [SPY, QQQ, AAPL, MSFT, NVDA, TSLA, META]
      output:

FAQ

Can OpenClaw track my actual P&L from my brokerage?

Not directly—OpenClaw doesn't connect to your brokerage account. The P&L tracking in the debrief agent works from your positions.yaml file (the same one used in Part 3) combined with end-of-day price data from Tradier. It computes estimated P&L based on the difference between your recorded entry price and the current market price of each contract. Your actual P&L from your broker will differ due to bid/ask spreads, commissions, and precise fill prices.

What should I do with the next-day watchlist the debrief generates?

The next-day watchlist is generated by combining three signals: (1) tickers where today's flow was elevated (from Part 2 data), (2) tickers with earnings in the next 1–5 days (from Part 4 calendar), and (3) tickers where IV rank moved significantly today (from Part 3 data). It's a starting point for your own pre-market research—not a trade recommendation. Review it alongside the Part 1 pre-market scan the following morning.

What time does the debrief run?

The debrief runs at 4:15 PM ET—15 minutes after the 4:00 PM close, giving time for final price data to settle and for after-hours earnings to be noted. Some data (like official closing IV) can take a few minutes to propagate through the API. If you regularly see stale data in your debrief, adjust the schedule to 4:30 PM.

How should I use the weekly debrief?

The weekly debrief on Fridays gives you a comprehensive view of the week: what worked, what didn't, which setups were profitable, which were noise. Use it to calibrate your strategy for the following week. If certain types of earnings setups worked well, plan more of those. If certain tickers or strategies lost money, plan to avoid or adjust them next week.
