Read the sample
Historical averages and positive-period frequencies depend on the chosen years, period, instrument and available observations. Missing history reduces what can be evaluated. A frequency is not the probability of a profitable future trade.
Separate the sources
Completed broker M1/D1 candles are an archive. Current broker depth is a separate snapshot of offered liquidity, not executed trades or a universal live quote feed. Delays, empty books and failed updates must remain visible. Coverage must be checked per instrument and data source.
Backtests and AI have limits
Backtests can be distorted by overfitting, look-ahead bias, selection bias, costs and missing data. AI explanations may contain errors. Verify inputs and conclusions independently; neither a backtest nor an AI explanation guarantees a future result.
