Free forex backtesting with no download: what you actually get
Four tools run in a browser with a free tier, and three more are free only after a download. In the browser: Formiq's free plan has no time limit, keeps replay practice and the trade journal uncapped, and allows 2 indicators at once and 3 backtests a day; FX Replay's Beginner plan holds 2 sessions and 50 records and keeps data for a week; Forex Tester Online offers a demo whose limits its site does not state; and TradingView's Basic plan is free but lists Bar Replay on the paid plans and shows daily bars and above. After a download: the MetaTrader Strategy Tester is free with the terminal but runs nothing without an expert advisor in MQL, Forex Tester 5's free version allows one hour per test and one month of data on Windows, and Soft4FX's demo allows 5 trades per simulation inside MetaTrader. What follows is what each of those sentences leaves out, read on each vendor's own site on the date shown.
Verified between 2026-07-27 and 2026-09-03; the date is shown against each tool. Formiq publishes this page, so treat the entry for Formiq as what it is. Everything stated about the other tools was read on that vendor's own site on that date, and each entry links to the page it came from. Prices are not quoted for the other tools because their checkout pages render different currencies and figures depending on where the request comes from.
New to this? How chart replay works, and the routine to use it
Free in the browser: what each tier holds back
Free tiers are shaped by what they withhold, and the four browser tools withhold different things. Formiq caps breadth — two indicators at once, three backtests a day, ten AI messages, with the exotic pairs, the indices and custom timeframes on the paid plan — and leaves depth alone: replay sessions and the journal have no cap and the plan has no end date. FX Replay caps depth — two sessions, fifty records, one week of retention — so the tool is fully there but the history is not kept. Forex Tester Online's demo is advertised as needing no credit card and nothing more is stated, so what it holds back is discovered after signing up. TradingView's Basic plan is a charting plan: two indicators per chart, one chart per tab, three alerts, ads, daily bars and above, and no Bar Replay, which its pricing table places on Essential and upward.
The practical difference is what you can do on the free tier for a month. On Formiq, a month of replay sessions is still there at the end of it and a rule can be tested three times a day throughout. On FX Replay, the two sessions are there but the records from the first week are not. On TradingView, the month is charting without replay. On Forex Tester Online, the answer depends on limits the site does not publish.
Free, but only after a download
The MetaTrader Strategy Tester is the free tool with the most depth on this page and the highest entry cost in effort: it ships with the terminal, models ticks five ways, optimises and forward-tests, and does nothing at all without an expert advisor written in MQL. A discretionary setup that has not been reduced to code cannot be tested in it. Forex Tester 5's free version is a Windows install whose limits the vendor states plainly — "You can test up to 1 month of historical data. You can test uninterruptedly for at least 1 hour" and "You can't save and load projects" — so it is a trial of the paid product rather than a free tier to work in.
Soft4FX's Forex Simulator belongs in the same group: a free demo of 5 trades per simulation and 2 sample years, with no saving, inside a MetaTrader terminal that has to be installed first.

Each free tier in detail
Listed alphabetically, not ranked. The first paragraph under each tool is what its free tier holds back; the rest is what the vendor's own site says the tool does, and where it stops whether or not you pay.
Forex Simulator (Soft4FX)
What the free tier holds back
Five trades per simulation, two sample years of data and no saving or loading, inside a MetaTrader 4 or 5 terminal that must already be installed.
A plugin that turns a MetaTrader 4 or 5 terminal into a replay simulator. You load tick history into the terminal, pick a start date, and the simulator plays the market forward at a speed you set while you trade it with MetaTrader's own order tools — so the practice happens on the same charts, indicators and templates you would trade live. The vendor states 10 to 20 years of tick data and over 26,000 copies sold.
What it does
- Replay inside MetaTrader 4 or 5 with pause, resume and speed control, and orders placed by dragging on the chart
- 10 to 20 years of tick data across 60 forex pairs, gold, silver, bitcoin, ethereum and 12 stock indexes, per the site
- Multi-timeframe charting; the MT5 version adds multi-currency sessions
- An economic calendar with event filtering, with data from 2007, and a trading-sessions window for New York, London, Tokyo and Sydney
- A risk-based position-size calculator, save and load of sessions, and Excel and HTML reports with statistics
- Free tier
- A free demo limited, in the vendor's words, to "Only 5 trades per simulation", "Only 2 sample years of data" and "No saving/loading". The full licence is a one-time payment covering 1 user and 2 MetaTrader accounts, with the MT4 and MT5 versions both included.
- Better than Formiq at
- Practice on the exact MetaTrader charts, indicators and templates you already trade with, on tick-level history.
- Where it stops
- It needs a MetaTrader terminal installed and runs only inside it, so it is tied to the machine that terminal is on. The site describes it as a replay simulator; testing a fixed rule automatically is not among the features listed — inside MetaTrader that is the Strategy Tester's job. The free demo stops at 5 trades per simulation and cannot save.
- Fits
- MetaTrader users who want replay practice without leaving the platform they trade on, bought once.

Forex Tester 5 (desktop)
What the free tier holds back
Saving, and time: one hour of continuous testing, one month of historical data and no saving or loading of projects, on a Windows install. A test that is not finished in the hour cannot be continued.
The desktop line of the same product: installed on Windows, bought once, and run against history downloaded to the machine, so it keeps working with the connection off. It covers both discretionary practice and automated logic, and a test is a saved project you can reopen and continue days later — which is the part the free version withholds. The paid tiers differ by the data bundled with them rather than by features.
What it does
- Basic Data: "25 years of medium quality real historical data. 18 symbols." Super Data: "25 years of premium quality real historical data. 860 symbols."
- "Test several currencies at the same time" and "Test several timeframes at the same time"
- A Strategy Optimizer using a grid algorithm to sweep parameter combinations
- Easy Forex Builder for assembling strategies, plus risk- and money-management tools
- With Super Data: tick data, and historical news for 9 currencies
- Projects save and reload, so a long test does not have to finish in one sitting
- Free tier
- A free version limited to one hour of continuous testing and one month of data. The full licence is a one-time purchase.
- Better than Formiq at
- Depth of history — the vendor advertises 25 years of data — and it keeps working offline once installed.
- Where it stops
- Windows only. The free version, in the vendor's words: "You can test up to 1 month of historical data. You can test uninterruptedly for at least 1 hour (then start another test, but you cannot continue the previous one). You can't save and load projects." So the one-hour cap and the missing save between them mean the free version cannot carry a test across sittings.
- Fits
- Long-horizon testing on a Windows machine, with a one-time payment rather than a subscription.

Forex Tester Online
What the free tier holds back
Not stated. The site advertises a free demo with no credit card required and does not say what the demo restricts, so the scope of free use is known only after signing up. Full access is a subscription.
A browser tool built for backtesting and nothing else. You pick an instrument and a period, open the chart, step the bars forward and place simulated orders as they arrive. Beyond manual practice it will test automated logic, and it will import your trade history from MT4, MT5, NinjaTrader or TradingView so that past trades can be analysed inside it. The distinguishing move is breadth: the same session can be run on a stock or a crypto pair rather than only on FX.
What it does
- 283 instruments per the site: 112 FX pairs, 23 indices, 49 crypto, 21 stocks, 29 futures, 47 ETFs and commodities
- Up to 23 years of tick data per symbol — the site claims "600M+ ticks per symbol, 2M+ bars"
- Up to 10 charts open and synchronised across different symbols and timeframes at once
- 92 built-in indicators, plus support for custom ones
- An Exit Optimizer that searches for stop-loss, take-profit and holding-time settings
- A prop-firm challenge mode that reproduces those rules and targets, and a blind-testing mode that hides the date and symbol
- A trade journal with tags, screenshots and confidence tracking
- Free tier
- A free demo, advertised as "no credit card required". Full access is a paid subscription.
- Better than Formiq at
- Coverage well beyond FX — stocks, indices, commodities, ETFs and crypto are all testable in the same tool.
- Where it stops
- What the free demo actually restricts is not stated on the site, so how far you can get without paying is unclear until you sign up. Full access is a subscription rather than a one-time purchase.
- Fits
- Testing one approach across several asset classes, in a tool built for backtesting first.

Formiq
What the free tier holds back
Two indicators at once, three backtests a day and ten AI messages a day, with the exotic pairs, the stock indices and custom timeframes on the paid plan; the 28 majors and crosses and gold are free. Replay practice, the trade journal and the plan's duration are not capped. The prices are historical, about two weeks behind, on every plan.
Open a browser tab and you get an FX chart you can rewind to a point in the past and then walk forward one candle at a time. You place a position without being able to see the next bar, carry it to the exit, and the result lands in a trade journal. If you want to test a rule rather than practise judgement, you assemble the entry and exit conditions from dropdowns and run a backtest over the history — no code, and no install step before either of those.
What it does
- Charts across 40 currency pairs plus gold and five indices, and 8 timeframes from M1 to monthly
- Replay with both auto-play and one-candle-at-a-time stepping, with the speed under your control
- A no-code strategy builder: entry and exit conditions picked from dropdowns, then backtested over history
- A trade journal and trade calendar that record every simulated position, plus an economic calendar
- Drawing tools — trendlines, Fibonacci and the rest — and the Fommy AI assistant for chart questions
- On the paid plan: unlimited indicators, unlimited backtests, custom timeframes such as 3min and 10min, and four pairs side by side
- Free tier
- Free plan with no time limit: 2 indicators at once, 3 backtests per day, AI assistant 10×/day. Replay practice and the trade journal are uncapped.
- Where it stops
- FX, gold and five indices — no individual stocks or crypto. Prices are historical rather than a live feed, every position is simulated, and there is no connection to a broker account. The free plan holds you to 2 indicators at once and 3 backtests a day.
- Fits
- Building screen time and testing simple rules without installing anything or committing money first.

FX Replay
What the free tier holds back
Two sessions, fifty records, one week of data retention and a one-month session duration, with one custom indicator and one screenshot and one checklist in the journal. The tool itself — TradingView-powered replay across forex, futures, stocks and crypto — is the same one the paid plans use.
A browser tool for manual replay, described on its own site as "built specifically for manual traders who want to practice execution, not just run automated scripts". You open a session on a market and a start date, step the TradingView-powered chart forward, place and manage simulated trades, and the trades land in a journal with screenshots and checklists. Coverage goes beyond FX — futures, stocks, indices and crypto are listed — and the site states data back as far as 2003 for major forex pairs.
What it does
- Manual bar-by-bar replay on charts powered by TradingView, from 5-second candles up to monthly
- Markets listed on the site: forex, futures, stocks, indices, crypto, agricultural, energy and metals
- Historical data stated as going back as far as 2003 for major forex pairs
- A journal with screenshots and checklists — 1 of each on Beginner, 2 screenshots and 3 checklists on Intermediate, unlimited on Pro
- FXR Script for custom indicators — 1 on Beginner, 3 on Intermediate, unlimited on Pro
- Data retention that scales with the plan: 1 week on Beginner, 6 months on Intermediate, unlimited on Pro, which also adds futures and CME data
- Free tier
- A free Beginner plan, listed on the pricing page as "2 sessions • 50 records • 1 week data retention • 1 month session duration", with 1 custom indicator and 1 screenshot and 1 checklist in the journal. Intermediate and Pro are billed monthly or annually.
- Better than Formiq at
- Market coverage beyond FX, and a journal built around screenshots and checklists, on TradingView charting.
- Where it stops
- Manual replay only: the site says it is for traders who want to practise execution "not just run automated scripts", and no rule-based backtest or MetaTrader export is described. The Beginner plan holds 2 sessions and 50 records and keeps data for 1 week, and the pricing page lists monthly and annual billing only, so a longer practice history means a subscription.
- Fits
- Discretionary traders who want to drill execution across several markets and keep a screenshot journal of every session.

MT4 / MT5 Strategy Tester
What the free tier holds back
Nothing is held back and nothing is provided: the tester is complete and free, and runs only an expert advisor written in MQL, after MetaTrader itself has been installed on Windows.
The testing engine bundled with the MetaTrader terminal, described by the documentation as a way to "test and optimize trading strategies (Expert Advisors) before using them for live trading". The unit of work is an Expert Advisor written in MQL: you point it at a symbol, a timeframe and a period, and it runs the program over that history and produces a statistical report. It is not a place to step through bars and make calls yourself — it is where a rule that is already fixed gets measured, and the same program then runs live on the same platform.
What it does
- Five tick-generation modes trading accuracy against speed: every tick, every tick based on real ticks, 1-minute OHLC, open prices only, and math calculations
- Visual mode, where "each trade is displayed on the chart of a financial symbol" and you can pause, speed up or slow down the run
- Optimization — running the strategy "several times with different sets of parameters which allows selecting the most appropriate combination"
- Multi-currency testing that automatically processes every symbol the strategy uses, without listing them by hand
- Forward testing, which splits the period 1/2, 1/3, 1/4 or at a date you choose and validates on the later part
- A report with the "balance curve (blue line) and the equity curve (green)", a histogram of load on deposit, and profit, trade count and many other statistics
- Multi-threaded execution across local and remote computing agents, and the MQL5 Cloud Network, which "brings together thousands of agents around the world"
- Free tier
- Free — it ships with the MetaTrader terminal. Running a strategy through it requires an Expert Advisor written in MQL.
- Better than Formiq at
- No ceiling on what a strategy can express, and what you test is what you can then run live on the same platform.
- Where it stops
- Nothing runs without an Expert Advisor, so if you cannot write MQL and have no code to start from, there is nothing to test. Windows desktop, and MetaTrader itself has to be installed first. A discretionary setup you have not reduced to rules cannot be expressed here at all.
- Fits
- Anyone who can write MQL, or whose strategy is going to end up as an EA regardless.

TradingView
What the free tier holds back
Bar Replay itself, which the pricing table lists on Essential and above, together with intraday history: Basic is daily bars and above, two indicators per chart, one chart per tab, three alerts and ads. Free TradingView is a charting plan without replay.
Primarily a charting and market-analysis platform rather than a testing tool. Practising on past bars is one feature inside it — Bar Replay, which rewinds the chart to a chosen point and steps forward from there — and the pricing table places it on the paid plans. Most of what you pay for is elsewhere: how many indicators fit on a chart, how many charts fit in a tab, how many alerts you can set, and how far back the history goes.
What it does
- Basic (free): 2 indicators per chart, 1 chart per tab, 3 price alerts, 1 watchlist of 30 symbols, ads shown, and historical data at daily resolution and above
- Essential and up: more indicators and charts, more alerts, and no ads
- Bar Replay is listed on Essential, Plus, Premium and Ultimate — not on Basic
- Historical bar depth scales with the plan: 20,000 bars on Premium, 40,000 on Ultimate
- Charting across many markets, with drawing tools, alerting and a large library of community scripts
- Runs in the browser and also has desktop and mobile apps
- Free tier
- The Basic plan is free and allows 2 indicators per chart, 1 chart per tab, 3 price alerts and 1 watchlist of up to 30 symbols, with ads. Its pricing table lists Bar Replay as available from the Essential plan upward, not on Basic.
- Better than Formiq at
- The charting itself — drawing tools, alerting, market coverage, and a very large library of community scripts.
- Where it stops
- On the free Basic plan you get neither Bar Replay nor intraday history — the pricing table puts Basic at daily bars and above — so practising on past intraday bars means paying. Chart-level limits are strict at the bottom of the range: one chart per tab and three alerts.
- Fits
- Analysis and charting across many markets, where replay is one feature among many rather than the point.

What free never includes, on any of them
None of these tools trades real money or connects a free tier to a broker, and none of the browser tools on this page runs on a live feed for practice — replay is by definition on past bars. Formiq states that its most recent candles are about two weeks behind the present; TradingView's free plan is daily bars and above; FX Replay's history reaches back to 2003 for major pairs but the free plan keeps a week of your own records. A free tier is a place to practise and to test, not a terminal.
How to choose
If the question is whether a rule makes money, the free routes are Formiq's three backtests a day and, with MQL, the MetaTrader Strategy Tester. If the question is whether you can execute, the free routes are Formiq's replay, FX Replay's two sessions, Soft4FX's five trades and Forex Tester 5's hour. If the question is charting with occasional replay, free TradingView does the charting and the replay is on the paid plans.
Whichever it is, read the free tier as a description of what the vendor expects you to pay for. Formiq expects you to pay for breadth, FX Replay for history, TradingView for replay and intraday data, and Forex Tester for time and saving.
Questions
Is there a completely free forex backtesting tool with no download?
Formiq's free plan runs in the browser with no time limit and no credit card: replay practice and the trade journal are uncapped, with 2 indicators at once and 3 backtests a day. FX Replay's Beginner plan is also free in the browser, with 2 sessions, 50 records and a week of retention. Forex Tester Online offers a free demo without stating its limits, and TradingView's Basic plan is free but without Bar Replay.
Can I backtest forex for free without MetaTrader?
Yes. Formiq tests a rule built from dropdowns in the browser, three times a day on the free plan, without MetaTrader or any code. FX Replay and Forex Tester Online also run in a browser; FX Replay is manual replay only, and Forex Tester Online's free demo limits are not stated.
Is TradingView's Bar Replay free?
TradingView's pricing table lists Bar Replay on the Essential, Plus, Premium and Ultimate plans and not on the free Basic plan, which is limited to daily bars and above with two indicators per chart.
Is the MetaTrader Strategy Tester free?
Yes — it ships with the MetaTrader 4 and 5 terminals at no charge. It requires the terminal to be installed on Windows and an expert advisor written in MQL; it does not test a strategy that has not been written as code.
Related comparisons
Formiq is free to start
Charting, replay practice, no-code backtesting and a trade journal in the browser. No install, no credit card. It is a practice and testing tool, not a broker — all trading inside it is simulated, and the price data is historical rather than live.
