FX Replay

FX Replay is a browser-based platform for practicing trading on historical market data. You open a backtesting session, replay the chart bar by bar, place simulated trades, and review the results in a built-in journal and analytics. FX Replay describes itself as “a backtesting and educational platform only”: it doesn’t execute real trades or hold client funds.

What FX Replay is, and what it isn’t

Replay, backtesting, journaling, and analytics are one workflow rather than separate tools. A session is where you replay a market, trade it, and record what happened; the journal, strategy analytics, and the Monte Carlo and risk-reward simulators then work on those practice trades. Backtesting here is manual: you trade the replayed chart yourself. The FX Replay sources we checked don’t describe automated or coded strategy backtesting.

FX Replay for futures traders

Futures are available only on the Pro plan. FX Replay’s asset page lists 20 futures, each labelled “Available brokers: CME”, “Pro only”, with 1-second bars as the smallest timeframe:

• Equity index: ES, NQ, YM, RTY, MES (Micro E-mini S&P 500), MNQ (Micro E-mini Nasdaq 100), MYM (Micro Dow)
• Energy: CL, NG, HO, RB
• Metals: GC, MGC (Micro Gold), SI, PL, HG
• Currencies: 6E, 6B
• Livestock: LE, HE

History starts on January 2 or 3, 2012 for most of these. The exceptions are RTY (from July 9, 2017), MES and MNQ (from May 5, 2019), and MYM (from September 30, 2020). In a session, FX Replay’s futures guide sizes one contract as one mini and 0.1 contract as one micro.

FX Replay labels this data CME, and an older help article names a “CME Futures Broker” as the source. It doesn’t say which company actually supplies the CME data.

Replay: bar by bar, and the “tick data” claim

The replay FX Replay documents is bar by bar: you step or play forward through candles, rewind (on paid plans), and jump to a date, down to 1-second bars for futures on Pro.

FX Replay’s FAQ also says it “uses real historical tick data rather than synthetic or interpolated price data.” At most, that describes the data its bars are built from. The FX Replay sources we checked don’t document a tick-by-tick replay mode, tick charts, or any market-depth, DOM, or order-flow view. Traders who practice by reading the order book should treat FX Replay as bar replay.

Orders and trading costs

FX Replay’s futures guide documents market and limit orders. Stop-loss and take-profit placement, and stop orders from the chart’s right-click menu, are documented generally, but how stop, stop-limit, or bracket orders behave for futures specifically isn’t documented.

You can add spreads and commissions when you create a session, and FX Replay says they’re configurable to match your own setup. Its help article on this uses only forex examples, so how per-contract futures commissions should be entered isn’t documented.

Journal, analytics, and Mentor AI

Every plan includes a journal for practice trades, with notes, tags, screenshots, and checklists attached to each trade. Paid plans add strategy analytics, a Monte Carlo simulator, and a risk-reward simulator. FX Replay describes its AI Trading Mentor as analysing the trades you take in backtesting sessions and giving feedback on them; AI usage is limited on Free and Intermediate and unlimited on Pro. All of this applies to trades taken in replay sessions, not to live trading.

Prop Firm Simulator

On the Intermediate and Pro plans, the Prop Firm Simulator enforces the rules you enter for a practice session: profit target, maximum drawdown, daily loss limit, minimum trading days, spreads, and commissions. There are no built-in presets for specific firms. FX Replay says it isn’t officially affiliated with any prop firm, and the simulator doesn’t compare or recommend firms.

Pricing and plan limits

The free plan is permanent, with no credit card and no automatic conversion. Intermediate and Pro both offer a free trial with no credit card required. FX Replay says its fees are “solely for platform access, software usage, and historical data hosting”, with no separate transaction fees or commissions, so futures data is included in the Pro price.

Subscriptions are non-refundable. FX Replay’s policy allows refunds to be considered only for confirmed duplicate charges or billing errors, or platform failures that prevented access for a significant part of the billing period. You can cancel at any time and keep access until the end of the billing period.

Where FX Replay’s own pages disagree

Some FX Replay details depend on which of its own pages you read. We report them as they are rather than choosing one:

• Which futures are listed. The asset page lists the 20 contracts above, including MYM. FX Replay’s futures landing page lists ZW (Wheat) instead of MYM; the other 19 match. An older help guide (February 2025) lists only five: ES, NQ, YM, RTY, and CL.
• Which plans include futures and seconds data. The pricing page, the asset page, and the seconds help article all say Pro only. The futures landing page’s plan cards list “Access to futures data” and “Access to seconds data” on every plan, including Free.

If either point matters to you, check FX Replay’s asset list inside the app before subscribing.

Where FX Replay falls short

The main limit for futures traders is fidelity: FX Replay documents bar replay, not tick-by-tick replay or depth, so it suits practicing entries, exits, and trade management rather than reading the order book. Futures require Pro, the CME data vendor isn’t named, futures-specific order and commission handling isn’t fully documented, and the non-refundable policy means the free plan and trials are the only way to evaluate it before paying.

Who FX Replay is best for

FX Replay fits discretionary traders who want to rehearse trades on historical charts in the browser, with futures, 1-second bars, and unlimited sessions on Pro, and a journal and analytics in the same place. It also suits traders practicing under evaluation-style rules they set themselves.

Who should look elsewhere

Traders who need tick-by-tick replay or depth should look at a trading platform with its own replay, such as NinjaTrader’s Market Replay. Traders who want automated strategy testing alongside manual practice can compare Forex Tester Online, and traders who want market replay in the same product as a journal of their real trades can look at TraderSync. Our trading journal comparison covers how the main journals handle replay and backtesting.
