FX Replay
Backtesting & replay platformFX Replay is a browser platform for replaying historical price data and trading it bar by bar. It combines market replay with a built-in journal, an AI review layer, and a prop firm simulator that runs a challenge's rules against your practice trades. There is a free tier; sessions, data retention and seconds-level data scale with the paid plans.
FX Replay gives SMCM readers 15% off with the code below, entered at checkout. This one is ours rather than a public promotion, so it is not on their pricing page and you will not find it anywhere else; it also pays us a commission at no extra cost to you. Their Head of Affiliates confirmed the code and the discount in writing. We have not watched the price change ourselves, because their checkout sits behind a signup, so treat the 15% as their statement rather than our measurement and check the total before you pay.

Where you can trade
A browser platform, so it is available wherever you can reach the site, with a free tier that needs no card. It is practice software rather than a broker: you cannot place a real order in it, and nothing here gives you access to a live account.
Eligibility depends on your country of residence and which entity you are onboarded to, and can change. Always confirm you can open an account — and under which entity — on the provider's official site before funding.
Our take
FX Replay is where you practise rather than where you trade. You load a market at a past date and step through it candle by candle, taking entries and exits as if it were live, and the platform records every one of them in a journal attached to that session. For a trader who has an idea but no evidence, that is the cheapest way to build a sample.
Two features matter for this audience specifically. The prop firm simulator applies challenge-style rules to a practice run, so the daily loss limit and maximum loss stop being abstract before any money is spent on an evaluation. And the journal is part of the same tool rather than a spreadsheet someone fills in afterwards, which is the point at which most journals die.
The honest limit is in the name: it is replay. Fills are simulated, the spread and slippage of the real session are not reproduced exactly, and knowing that the bar you are looking at is historical changes how a person behaves. It is a place to test a rule and to count, not a proof that the rule will pay.
Pros
- Free tier with no card, so the tool can be tried before paying
- Journal, replay and analytics in one place rather than three
- Prop firm simulator applies challenge rules to a practice run
- Seconds-level data on the Pro plan for fast-market testing
Cons
- Simulated fills: spread and slippage are not the live market's
- Data retention, sessions and indicators are limited on the free and Intermediate plans
- Hindsight bias is unavoidable when the data is historical
- Not a broker and not a route to a live account

FAQ
- Is FX Replay free?
- There is a free plan with no card required: 2 sessions, 50 records and a week of data retention, checked on 2026-09-17. The paid plans raise those limits and add seconds-level data.
- Can I trade real money on it?
- No. It replays historical data and simulates your fills. It is practice and record keeping, not execution, and it is not a broker.
- Does backtesting prove a strategy works?
- No. It gives you a sample instead of a feeling, which is a real improvement over nothing, but simulated fills ignore the spread and slippage of the live session and hindsight quietly flatters every decision.
