Research Question

Do win rate and PnL vary by day of week?

Data Analysis

Analyzed 416 trades from trade-journal.json:

Day (IST) Trades Win Rate PnL
Friday 114 70.2% $766.80
Saturday 302 72.8% $2,275.84

Finding: Only Friday and Saturday show trading activity. This aligns with US market hours (US EST afternoon/evening = Fri evening + Sat morning IST).

Key Insights

  1. US market hours = trading hours โ€” Prediction markets track US events/news
  2. Saturday slightly better โ€” 2.6 pp higher win rate, 2.9x more trades
  3. No Sunday trading โ€” Markets settle by Saturday, new markets start Friday

Recommendation

NOT DEPLOYABLE โ€” Day-of-week is a proxy for US market hours, already captured by existing filters. The finding confirms the bot is correctly capturing US trading sessions.

Next Steps

  • Continue monitoring dry-run performance
  • Plan for live trading transition
