Extrapolator - indicator for MetaTrader 5

A free, fully open JPN225 (Nikkei 225) EA for M15. Buys when price leans up, momentum isn't stretched and volume is quiet. Backtest 2022 to 2026: profit factor 1.68, +18.5% a year, passed 15 stress tests. Flat by 17:00.

Audits the tick history that 'Every tick based on real ticks' backtests replay. Five checks per symbol over the last N days: impossible and crossed quotes, timestamps that run backwards or repeat, one-tick price reversals sized in multiples of the symbol's own median spread, silences inside the broker's declared quote sessions, and minutes where the ticks and the M1 bars disagree. Every finding goes to CSV with its millisecond timestamp, and the tool prints its own arithmetic so the report can be recounted. Read only: no trade function, no DLL, no network.
