Solid replay engine
Solid replay engine, custom indicators need work The core replay is good and the TradingView-based charting feels familiar right away. Multi-timeframe sync works well and skipping weekends speeds up backtesting a lot. The custom indicator system (FXR Script) is a great idea but feels early. Documentation is incomplete — several drawing functions have signatures that don't match the docs, so you find out by trial and error. More importantly, scripts can only read the bars loaded in the current session, which caps historical depth at a few months on higher timeframes. Building monthly levels is impossible, even though the underlying data goes back years. Pine's request.security solves this on TradingView. Still using it, and the fundamentals are there. Would rate higher with deeper data access for custom indicators and better docs
