Fillbook. Its Pro plan ($14.99/mo) costs less than TradeZella's lowest paid tier ($35/mo), and Fillbook also offers a free plan with no time limit, which TradeZella does not.
TradeZella does, on its Pro tier and up. Fillbook's Backtest tool is a manual what-if trade builder — you construct hypothetical trades and see the resulting metrics — not automated replay against historical market data.
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 at every paid tier.
