Fillbook - A trading journal that watches trades, not just logs them

Fillbook is a trading journal for futures and prop-firm traders. Instead of logging P&L after the fact, it watches your trades for real-time behavioral patterns — revenge trading, overtrading, weak trading hours — and fuses those with live drawdown status against your firm rules (Apex, Topstep, Bulenox). Most journals cannot say "revenge trading, and $180 from your floor" — they do not track both at once. Free plan includes futures support and R-multiple tracking. English, Spanish, French.
