Research Note Divergence Intraday — 1-Year Refresh on 5,073 Trades
Re-ran the 15-minute divergence backtest on a 4.5× larger sample: 5,073 trades, 144 symbols, PF 1.50×, 31.4% win rate. The ATR stop floor cut first-bar stop-outs from 41.3% to 29.2%. Confirmed on the larger sample that 100% of profit comes from positions held past the close — the intraday portion loses money. Capping concurrency at 5 positions removes 42% of the profit.
