Most FXReplay comparisons compare the wrong two things. They line up replay against replay, decide whose bars move more smoothly, and stop there. That comparison is too small to be useful, and it flatters the smaller product.
The question that actually decides it is what happens after the session ends. Practice is an input. The output you care about is whether your live account changed, and answering that needs your real broker fills. FXReplay can now collect some of them: its Live journal syncs cTrader and TradeLocker, with MT4, MT5, NinjaTrader and Tradovate listed as coming soon and CSV upload in the meantime. That is a real feature and most comparison pages, including an earlier version of this one, missed it. What it is not is coverage: two live connections in the forex-platform lane, with no stock, options, futures or crypto brokers at all.
Then the second half of the question: what can the product do with the fills once it has them? FXReplay gives you entry, exit, PnL, duration, size, screenshots, notes and tags. That is a log. It is not MFE/MAE, best-exit analysis, R-multiple distributions, drawdown, running P&L, plan adherence, options spread lifecycle or a pivot grid you can slice by any dimension. A trader can sync every trade and still have no answer to: did my real exits improve, which setups stay profitable at size, what would a different stop have done to the trades I actually took, and what did my funded account do under the firm rules?
The second thing these comparisons skip is the caps. FXReplay’s own pricing page keeps 1 week of data on Free and 6 months on Intermediate, with 50 and 200 trade records per session. Review that spans a year is a Pro-only capability there. Any journal comparison that ignores retention is comparing feature names, not usable products.
The TradesViz claim is narrow and checkable: it is the one holding your real trading record, so it is the one that can tell you whether the reps worked. It imports real trades, computes deterministic analytics, overlays actual fills on TradingView charts, replays those trades, simulates stocks, futures, forex, crypto, indices and options, tests rules with a separate technical backtester, analyzes options chains and spreads, runs AI Coach, AI Query, AI Chat and AI Notes, and connects the journal to screeners, options flow, seasonality, fundamentals, SEC13F and prop-firm compliance.
