Which is better for a futures trader?
Both confirm futures support. Stonk Journal states "proper contract multipliers" for futures and forex; Fillbook calculates P&L per contract using each instrument's actual tick and point value.
Which is better for a prop-firm trader?
Both track prop-firm-relevant rules. Stonk Journal offers separate account tracking plus weighted compliance scoring; Fillbook tracks trailing/static drawdown, daily-loss, and consistency against your account's specific rules, with breach alerts.
Which provides stronger behavioral analysis?
Fillbook runs rule-based detection for revenge trading, overtrading, and time-of-day decay. Whether Stonk Journal's AI Coach performs equivalent pattern detection (beyond its stated dollar-impact quantification) wasn't independently verified.

Fillbook does, from Core up: NinjaTrader and Tradovate auto-sync and are verified against live accounts, while Interactive Brokers auto-sync is in Beta — not yet verified against a live account, so CSV import is the current path for IBKR. Stonk Journal states broker auto-sync is on its roadmap, not currently available.
Partly — after a 14-day free trial Fillbook keeps a permanent Free plan for one account (unlimited trades, plus the drawdown, daily-loss and consistency buffer). Stonk Journal's free plan has no trade or account limits, while Fillbook's paid plans include named R-multiple and expectancy metrics.
Stonk Journal's Pro tier ($10/mo) costs less than Fillbook's Core plan ($14.99/mo). Fillbook's automated broker sync starts at Core, with one supported connection included in the 14-day free trial; Stonk Journal doesn't currently offer broker sync at any price.
