If this is you
Choose FX Replay
You want a backtester rather than a replay: trades placed on the replayed chart and recorded as you go. You also want analytics, a prop firm simulator and data down to seconds, across several markets.
FX Replay vs TradingView Bar Replay
FX Replay vs TradingView Bar Replay: which to backtest with
FX Replay and TradingView Bar Replay both replay history candle by candle. FX Replay is built to backtest: orders fill on the replayed chart and land in a journal. Bar Replay goes wide on markets and Pine Script®, but its orders fill on real time data. BacktestFlow goes deep on forex: every trade recorded, every finding checked for significance.

The difference that decides it
Replaying a chart is not the same as testing a strategy.
Both tools move a historical chart forward one candle at a time, so they look alike. The difference is what happens when you act on what you see.
A backtest needs three things: a fill at the chart's price, a record of the trade, and statistics from enough records to mean something.
FX Replay is built around all three. You place the order on the replayed chart, it fills there, it lands in the journal, and the analytics update. TradingView Bar Replay covers only the first part, and not quite that. Its documentation says that trading orders during replay, Paper Trading included, are executed using real time data. The order panel is live while the chart is in the past.
So backtesting with Bar Replay means keeping the book yourself. Step the chart, decide, and write the entry, stop and target into a spreadsheet. Step until one of them is hit, write the result, and compute the statistics at the end. The cost is time. The risk is the trades that never reach the sheet. That is how a record ends up too thin or too flattering to conclude anything from.
That is why FX Replay leads more rows below than TradingView does. Bar Replay leads where TradingView as a platform leads: markets, Pine Script®, and costing nothing extra if you already use it.
If you are weighing FX Replay against a forex first tool instead, our FX Replay alternative page puts it next to BacktestFlow row by row, including where FX Replay leads. If Bar Replay is what you use now, the TradingView Bar Replay alternative page does the same for it.

FAQ
Frequently asked questions. About FX Replay, TradingView Bar Replay, and the differences.
For backtesting specifically, yes. FX Replay is built around trading the replay: orders fill on the historical chart, trades go into a journal, and analytics follow. TradingView Bar Replay replays price, but its documentation states that orders during replay execute on real time data, and it keeps no record. TradingView leads on charting; FX Replay leads on backtesting.
Not against the replayed prices. TradingView's Bar Replay documentation says trading orders are executed using real time data, including Paper Trading orders. It adds that the trading panel shows real time quotes while replay is on. You can draw, use indicators and step the chart forward, but a simulated trade on the historical bar has to be tracked by hand.
Bar Replay is part of TradingView, but how far back you can replay intraday data depends on your plan. We quote no prices, so check TradingView's own pricing page.
It depends on the timeframe. On forex minute data they are close. FX Replay lists major pairs from 2002 to 2005, depending on pair and feed. TradingView lists EURUSD one minute data from November 2001. Below one minute, FX Replay offers 5 second candles on many pairs, while TradingView's second based bars start on August 17, 2022. On daily data, TradingView goes back decades.
Both go wide: FX Replay across many markets and seconds data, Bar Replay across everything TradingView lists. BacktestFlow goes deep on forex. Statistics read in pips, multi hour candles sit on the 17:00 New York grid, and the replay waits until every trade is recorded. Flow Coach keeps a finding only if it passes a significance check.
