Detect lookahead bias before using a strategy

Check whether a strategy uses future candle information unavailable at decision time.

Goal

Goal: Check whether a strategy uses future candle information unavailable at decision time.

Download target data and run a baseline backtest. [lookahead]
Run freqtrade lookahead-analysis --strategy MyStrategy --timerange 20230101-20250101. [lookahead]
Inspect flagged indicators/signals, fix populate_*, then rerun analysis and backtest. [lookahead]

All bias flags are explained or fixed, and corrected results are compared with baseline.

The command may stop with too few trades; increase data or narrow the conclusion.

Python 3.11+, Freqtrade installed, a pinned strategy, and a local user-data directory.

Use public market data and local history; treat every trading decision as research and never connect a live account.

The analyzer has caveats; no warning does not prove absence of bias.

These values describe the upstream repository, not popularity or likes for an individual skill or playbook.
