Backtest your own entry rule on up to 10 years of real daily bars: RSI(2), RSI(14), IBS, drawdown-from-20d-high, consecutive down days, SMA cross, or gap down. Next-open fills so there is no look-ahead, slippage charged both sides, train/test halves scored separately, buy-and-hold and SPY baselines ALWAYS printed, and disagreeing halves reported as noise instead of a result. · Keywords: trading-strategy, quant, no-look-ahead, research · Built with @piprail/sdk
