Which is better for a futures trader?
Both support futures with contract/tick-level math — TradeZella via a dedicated calculator confirming 28+ contracts, Fillbook natively in every logged trade's P&L, R-multiple, and position sizing.
Which is better for a prop-firm trader?
Both track prop-firm rules. TradeZella covers 15+ named firms with pass-rate forecasting; Fillbook tracks trailing/static drawdown, daily loss, and consistency against the rules you set, with breach alerts, on its Core plan ($14.99/mo) — still less than TradeZella's $35/mo entry tier.
Which provides stronger behavioral analysis?
TradeZella markets AI-driven trade-leak detection through specialized agents. Fillbook runs rule-based detection for revenge trading, overtrading, and time-of-day performance decay directly from your trade history, plus an AI chat assistant that can answer questions about those patterns in your own data.
Which costs less?
Fillbook: 14-day free trial, no card required, then a permanent Free plan for one account, Core $14.99/mo (adds prop-firm rule tracking), or Elite $24.99/mo (Fillbook pricing updated 2026-10-13). TradeZella: no free tier, $35–$99/mo depending on tier (checked 2026-10-04, see the table above for exact tier contents).

Fillbook's Core plan ($14.99/mo, adds multi-account prop-firm rule tracking) costs less than TradeZella's lowest paid tier ($35/mo), Fillbook also has a permanent Free plan for one account, and every new account gets a 14-day free trial with no card required.
TradeZella does, on its Pro tier and up. Fillbook's Backtest tool has a manual what-if trade builder plus a Preview: automated backtesting from your uploaded historical data (Elite) — it runs only against a historical bar file you upload yourself, not a centralized market-data feed like TradeZella's.
TradeZella's tick-by-tick replay with drawing tools (Pro tier and up) is more full-featured for chart analysis. Fillbook's replay overlays your planned stop on the trade's chart, which is more limited but included on Core and Elite (not Free).
