This is one of the more transparent strategy audits I’ve seen. Disclosing the broken bracket logic, outlier dependence, same-sample tuning, and recency concentration adds far more credibility than presenting only the final equity curve. A few tests could strengthen the underlying theory considerably: 1. Verify the actual fill times. On a one-hour chart with process_orders_on_close=true, a condition detected on the 01:00 bar may fill at that bar’s close, closer to 02:00. The trade export should confirm whether the strategy tested the intended 01:00–18:00 window or a shifted window. 2. Reconstruct the trades with lower-timeframe data. Hourly OHLC cannot always prove whether the stop or target was reached first inside a candle. I’d rerun it with Bar Magnifier and independently reconstruct at least the bracket-touching trades from minute data. 3. Freeze this exact configuration now. Keep Monday, the entry and exit times, ATR length, 3× stop, and 4× target unchanged. Future observations should be treated as true out-of-sample evidence rather than another opportunity to adjust the rules. 4. Run weekday controls. Apply the exact same window and brackets to Tuesday through Friday. This would show whether the result is genuinely Monday-specific or simply reflects the Nasdaq’s general long-term upward drift. 5. Run nearby-time placebo tests. Test a small, predefined group of neighboring windows—not a complete optimizer grid. A durable time effect should generally weaken gradually around the chosen window rather than disappear immediately one hour away. 6. Test unchanged logic on other index futures. MES and MYM would be useful controls. Confirmation across related instruments would support a broader liquidity or behavioral explanation. Failure elsewhere would suggest the result may be MNQ-specific or sample-specific. 7. Use actual individual contracts or document the continuous-contract settings. Rollovers and back-adjustment can alter historical prices and ATR calculations. It would be useful to confirm results using the contracts that were actually tradable at each date. 8. Replace ordinary trade bootstrapping with block or regime-aware resampling. Individual-trade bootstrapping assumes trades are independent and mixes different market regimes together. Resampling consecutive blocks would preserve losing streaks, volatility clusters, and changes in market behavior more realistically. 9. Break down the top 19 trades. I’d examine whether they cluster around major news, holiday weeks, volatility events, contract rolls, or one particular year. If the largest winners share a repeatable market condition, that may reveal the actual edge. If they are unrelated accidents, the residual strategy is much weaker. 10. Test by regime. Separate bull, bear, high-volatility, low-volatility, and major-event periods. The final window producing 45% of total profit may indicate that the edge is conditional rather than permanent. 11. Use realistic live execution assumptions. Include delayed entry, spread, commissions, slippage, missed fills, exchange holidays, shortened sessions, and gaps through the stop. I’d also verify the distinction between “six ticks per order” and “six ticks round trip.” 12. Forward-test without modification. Run it in paper trading for a meaningful number of Mondays and compare expected versus actual signal time, fill, slippage, stop behavior, and P&L. Record every difference rather than judging it only by whether the trade won.
