What is Forex Tester?
Forex Tester is desktop and web software for testing a trading strategy against historical data. There are two live products. Forex Tester Online (FTO) is the current flagship, a web-based application launched in 2024 that covers 272 instruments across forex, crypto, stocks, indices, ETFs, futures, and commodities, and bundles tick data into the license. Forex Tester Desktop is the legacy Windows-only application; its own download page self-labels as the “old version.”
Both support the core job: manual visual replay of price action with speed control, multi-timeframe and multi-currency charts, and an economic calendar overlay. The desktop edition adds automated EA testing in C++ or Delphi and an AI Strategy Optimizer. FTO Pro adds an Exit Optimizer, a prop-firm challenge simulator, and a blind-testing mode designed to stop you peeking ahead. It is not an MT4 or MT5 plugin and it is not a TradingView feature. It is standalone software, and unregulated software status is normal and expected here, not a warning sign.
Our verdict
Forex Tester is a capable, established, and genuinely useful backtesting tool that earns a solid but qualified score. The strengths are real: a mature manual-replay engine, broad instrument coverage, automated testing and optimization on desktop, and an unusually honest set of backtest-versus-live disclaimers in its own terms and blog. The caveats are equally real. The paid tick data that the entire accuracy pitch rests on comes from a source the vendor never names and that no external party has audited. The pricing is fragmented across two products and, on desktop, stacks a recurring data subscription on top of the license. And FTO, the product the company is steering buyers toward, has been reported as buggy since launch, including an acknowledged H4 candle-misalignment issue, which is awkward next to marketing that promises “the most accurate backtesting results.” None of that makes it a bad buy. It makes it a buy you go into with open eyes.
We assess Forex Tester from its public pages, its own blog, pricing and refund policy, terms, and aggregated user sentiment across BabyPips, SourceForge, Capterra, Trustpilot, and Scamadviser. We have not purchased a license or run trades.
Key features & specs
The headline is that this is a manual, visual replay tool with automated testing on desktop, sold as two separate products. FTO is web-based with tick data bundled into a one-time license; the legacy desktop is Windows-only with tick data sold separately as a recurring Super Data subscription. Both do manual replay well, with speed control, multi-timeframe and multi-currency charts, and an economic calendar. Only desktop does automated EA testing (C++/Delphi) and AI optimization; only FTO Pro does the Exit Optimizer, prop-firm challenge simulator, and blind-testing mode. Coverage is broad: FTO spans 272 instruments across forex, crypto, stocks, indices, ETFs, futures, and commodities, while desktop Super Data reaches 860+ symbols. Two features traders often expect are absent: walk-forward analysis and Monte Carlo simulation are not documented for either product, so do not buy on the assumption they exist.
| Attribute | Value | Source |
|---|---|---|
| Company & track record | Operated by Forex Tester Software Inc., registered in Ontario, Canada, with a reported operational base in Ukraine that comes from third-party staff and directory sources only, so we treat it as reported rather than register-verified. The product line traces back to around 2006 and has been continuously maintained since, progressing through several desktop versions to the current web-based Forex Tester Online (launched 2024). That longevity is a genuine positive in a category littered with abandonware. No named principals are listed on the official About page and no company registration number was located, so we treat the corporate detail as reported. | Forex Tester ↗ |
| Software status | A backtesting and strategy-testing application, not a broker, adviser, or funded-trader program. It holds no financial licence and is not financially regulated, which is normal and expected for backtesting software that touches no client money. Its own terms state the software “is not intended for real money trading.” No financial-regulator warning naming the product was found, and Scamadviser rates the domain “very likely not a scam.” | Forex Tester terms ↗ |
| Pricing & plans | Two distinct products with different pricing. Forex Tester Online (FTO), the current flagship, sells one-time “lifetime” licenses with tick data bundled in: Starter at €135 (regularly €169) and Pro at €239 (regularly €299) in the June 2026 sale. An FTO subscription also exists, but its current price is not disclosed on the official page at our access date because the pricing page returns a 404. Forex Tester Desktop is a one-time license plus a separate recurring Super Data subscription for tick data, all ex-VAT: license-plus-Basic from $149 (regularly $230), up to a $469 lifetime-data bundle. Super Data standalone is $30/mo, $199/yr, or $369 lifetime. | Forex Tester pricing ↗ |
| Free tier & trial | The desktop Basic tier uses free Forexite M1 (one-minute) data, but the free version is limited and tick-level testing requires payment, so there is no fully free unlimited tier. A formal trial is not clearly disclosed; instead the refund guarantees function as a money-back window: 14 days on desktop and 30 days on FTO for the initial payment (7 days for subsequent payments). | Forex Tester data sources ↗ |
| Platform & compatibility | FTO is a browser-based web app (shipped 2024). The legacy desktop product is Windows-only, and its own download page self-labels as the “old version.” There is no verified macOS-native build, no MT4/MT5 plugin, and no cTrader or NinjaTrader integration. Desktop supports CSV/txt data import. If you need testing inside MetaTrader, this is not that tool. | Forex Tester ↗ |
| Data quality & sources | The honesty splits sharply by tier. The free/Basic source is named: Forexite, delivered as M1 one-minute bars, 18 symbols, medium quality, with documented “bad bars” complaints in trader forums. The paid tick data, Super Data on desktop and the tick data bundled into FTO, is where the whole accuracy value proposition lives, and here the vendor never names the source and no external audit exists. FTO advertises 272 instruments and desktop Super Data covers 860+ symbols, but breadth is not provenance. The vendor's “premium quality” and “we are 100% sure” lines are unverifiable marketing. | Forex Tester history service ↗ |
| Execution modelling | Execution realism is conditional, not out-of-the-box. Floating/variable spread requires the paid tick tier; on free M1 data the spread model is not realistic. Spread, commission, and swap are configurable, and testing is tick-level only with paid data. Slippage, latency, and news-event spread widening are described as “simplified” by independent sources, and the auto-slippage fill model is not documented, so we neither assert nor rule out specific fill behaviour. Because testing is manual bar/tick replay, structural look-ahead bias is limited. | Forex Tester ↗ |
| Mode, features & honesty | Both products do manual visual replay with speed control, multi-timeframe and multi-currency charts, and an economic calendar. Desktop adds automated EA testing in C++/Delphi and an AI Strategy Optimizer; FTO Pro adds an Exit Optimizer, a prop-firm challenge simulator, and a blind-testing mode. Walk-forward analysis and Monte Carlo are not documented for either product. On honesty the vendor scores well: its terms state hypothetical results are “prepared with the benefit of hindsight” and “may differ significantly from actual trading results,” and its blog calls backtesting “a filter, not a crystal ball.” Every accuracy figure it publishes (“almost 100% quality of testing,” optimizer “up to 99% / 95%”) is marketing about data granularity or parameter-search coverage, not measured backtest fidelity. | Forex Tester blog ↗ |
Pricing & value
Pricing is where Forex Tester gets complicated, and buyers should slow down here. On FTO, the June 2026 sale lists a Starter “Lifetime” license at €135 (regularly €169) and a Pro “Lifetime” license at €239 (regularly €299), each a one-time payment with tick data included. There is also an FTO subscription, but its current price is not disclosed on the official page at our access date, because that pricing page returns a 404. FTO carries a 30-day money-back guarantee.
On Desktop, the model is a one-time license plus a separate recurring Super Data subscription for tick data, all quoted ex-VAT. The license-plus-Basic bundle is $149 (regularly $230) but uses only the free Forexite M1 data. To get tick data you add Super Data at $30 a month, $199 a year, or $369 lifetime, sold either standalone or in bundles up to the $469 lifetime package. The cost-stacking is the real story: serious tick-level testing on desktop forces an ongoing data cost on top of the license. The desktop “lifetime” license is also version-locked, meaning minor upgrades are free but major-version upgrades carry a paid fee, and whether the $369 Super Data “lifetime” tier includes perpetual future data updates is not disclosed. Against a free built-in MT4 or MT5 strategy tester, or TradingView's bar replay, Forex Tester justifies its price mainly through a smoother manual-replay workflow and broader bundled data, not through anything the free tools cannot technically attempt.
FTO: one-time “lifetime” license (plus an undisclosed subscription); Desktop: one-time license + separate recurring Super Data tick subscription| Edition | Price | Billing | What's included / data tier | Best for |
|---|---|---|---|---|
| FTO Starter | €135 (reg €169) | One-time “Lifetime” | Bundled tick data, 272 instruments, manual replay | Solo discretionary backtesters |
| FTO Pro | €239 (reg €299) | One-time “Lifetime” | Adds Exit Optimizer, prop-challenge simulator, blind-testing | Serious / prop-track testers |
| Desktop + Basic | $149 (reg $230) ex-VAT | One-time license | Free Forexite M1 data only, EA testing, AI optimizer | Windows users on a budget |
| Desktop + Super Data | $169 bundle to $469 lifetime | License + data subscription | Adds paid tick data (source unnamed), 860+ symbols | Windows users needing tick-level tests |
Transparency & trust
A backtest is only as honest as the data and the fill model behind it, so this is the decisive part of the review. On data, the honesty splits sharply by tier. The free and Basic data source is named: it is Forexite, delivered as M1 one-minute bars, covering 18 symbols at medium quality, and the community has documented “bad bars” complaints against it. On free M1 data, spreads are not realistic and lower-timeframe or scalping tests are unreliable. The paid tick data, Super Data on desktop and the tick data bundled into FTO, is where the accuracy value proposition lives, and here the vendor never names the source and no external audit exists. FTO advertises 272 instruments and desktop Super Data covers 860-plus symbols, but breadth is not the same as provenance. A buyer paying specifically for tick accuracy is paying for data whose origin is undisclosed.
Every accuracy figure Forex Tester publishes is marketing, not measurement, and should be read that way. “Almost 100% quality of testing” describes data granularity, not accuracy. The optimizer's “up to 99%” or “95%” refers to parameter-search coverage, not backtest fidelity. FTO's claim that it “eliminates future data leakage” and delivers “the most accurate backtesting results” is an unaudited architecture claim. To be fair and precise: no independent party has found a look-ahead bug either, so the honest position is that there is no verification of the no-leak claim and no reported leak either. Execution realism is conditional, not out-of-the-box. Floating or variable spread requires the paid tick tier; on free M1 data the spread model is not realistic. Slippage, latency, and news-event spread widening are described as “simplified” by independent sources, and the auto-slippage fill model is not documented. That is a reasonable engine, but it is not the flawless realism the marketing implies, and FTO's reported launch bugs, including the support-acknowledged H4 candle-misalignment issue, are a genuine correctness risk sitting directly against bold accuracy copy.

Forex Tester Terms of Service, Terms of Refunds (Desktop), accessed June 2026 TOS ↗
On regulation, software like this is not financially regulated, and that is entirely normal. It is not a broker and holds no client money, so the absence of a license is not a mark against it. What does count is provenance and candour, and on candour the vendor scores well in one important place. Its own terms and blog carry clear backtest-versus-live warnings, including the line “Backtesting is a filter, not a crystal ball. Validate with forward testing and out-of-sample testing before going live.” That is more honesty than most of this genre offers. The refund terms are documented: desktop carries a 14-day unconditional money-back guarantee, and FTO allows cancellation within 30 days of the initial payment and 7 days of any subsequent payment, refunding only the last payment in a multi-payment scenario. Curve-fitting remains the standing caveat for any backtester: a beautiful historical equity curve is not live performance, and Forex Tester, to its credit, says so itself.
What traders say
Aggregate ratings are positive but thin, so weight them carefully. Trustpilot sits around 4.1 out of 5 across roughly 111 reviews, with the company replying to 100% of negatives, though our read of that score is snippet-level and lower confidence. Capterra shows 4.5 out of 5 but from only 2 reviews, and SourceForge 4.7 out of 5 from just 3, samples too small to lean on. Scamadviser rates the domain “very likely not a scam.” The community themes are more useful than the stars.
The recurring positives are reliable manual replay and a workflow that genuinely helps people practise. One BabyPips user, Jadzia.Daxtrader, wrote in September 2025: “I wouldn't have been a profitable trader over the last two years, without any reliable backtesting facilities.” The recurring negatives are FTO's bugs and the cost of tick data. Beaylemo, also on BabyPips in August 2025, captured both: “Half a year ago I wouldn't have recommended the software (online one) due to numerous bugs,” adding that “tick data, required for lower timeframes backtesting and especially scalping comes with extra costs.” Be aware that some glowing third-party write-ups are affiliate content, so treat marketplace ratings as directional, not decisive.

Pros & cons
The balance below reflects a mature tool with specific, well-understood trade-offs rather than vague impressions. The pros cluster around longevity, manual-replay quality, breadth, and disclosure honesty; the cons cluster around undisclosed paid-data provenance, cost-stacking, FTO's launch bugs, and missing analytics like walk-forward and Monte Carlo.
- Mature, continuously maintained since ~2006 by an Ontario-registered company, with responsive support
- Strong manual visual bar/tick replay with speed control, the core strength for discretionary testing
- Broad coverage: FTO 272 instruments across forex, crypto, stocks, indices, ETFs, futures, commodities; desktop 860+ symbols
- Multi-timeframe and multi-currency testing, plus economic calendar overlay
- Desktop automated EA testing (C++/Delphi) and AI Strategy Optimizer; FTO Pro adds Exit Optimizer, prop-challenge simulator, and blind-testing mode
- Unusually honest backtest-vs-live disclaimers in its own terms and blog
- Documented refund guarantees (desktop 14-day, FTO 30-day) and a free Forexite M1 data tier named openly
- Paid tick data the entire accuracy pitch depends on comes from a source the vendor never names, with no external audit
- Cost-stacking on desktop: serious tick testing forces a recurring data subscription on top of the license
- FTO reported “extremely buggy since launch,” including a support-acknowledged H4 candle-misalignment bug, against bold accuracy marketing
- No walk-forward analysis and no Monte Carlo for either product; no MT4/MT5 plugin
- Fragmented two-product pricing with the FTO subscription price undisclosed (page 404s) and “lifetime” licenses version-locked
Forex Tester vs alternatives
Against the free built-in MT4 and MT5 strategy testers, Forex Tester's pitch is a far better manual visual-replay experience and broader bundled data, since MetaTrader's tester is built for automated EA runs and its visual mode is clumsy. Against TradingView's bar replay, Forex Tester offers deeper multi-currency testing, desktop automation, and configurable spread/commission/swap, where TradingView's replay is lighter and browser-bound but free or low-cost.
The catch is that MetaTrader and TradingView both either name or let you supply your data, whereas Forex Tester's premium tier asks you to trust unnamed tick data. Against other paid replay tools, Forex Tester competes well on track record and instrument count, but its lack of walk-forward and Monte Carlo means quant-leaning testers may still need a second tool.

Who is Forex Tester for?
Use Forex Tester if…
Use Forex Tester if you are a discretionary or price-action trader who wants a smooth, fast manual bar-by-bar replay across many instruments, you value a long-maintained tool with responsive support, and you understand that realistic tick-level testing means paying for data whose source is not named. The desktop AI Strategy Optimizer and FTO Pro's prop-firm challenge simulator are useful bonuses if you code EAs or are working toward an evaluation.
Skip it if…
Skip it if you need testing inside MT4 or MT5, you require walk-forward or Monte Carlo, you trade scalping strategies on free M1 data, or you want audited, fully-disclosed data provenance before you trust a backtest with real-money decisions.
Final verdict
Forex Tester is a legitimate, established, and genuinely useful backtesting tool that does the core job well and is unusually honest about the limits of backtesting itself. It loses ground on three concrete points: the paid tick data its accuracy pitch depends on comes from an unnamed, unaudited source; pricing is fragmented across two products and stacks recurring data costs on desktop; and FTO, the product being pushed, has shipped with real bugs against bold accuracy marketing. Weigh the platform fit and the data-provenance gap against the price, and treat any “almost 100%” figure as marketing. It is a solid, qualified recommendation, not a flawless one. We score Forex Tester 6.8 out of 10.
A long-established, capable backtester with strong manual replay and honest backtest-vs-live disclaimers, but its premium accuracy rests on tick data from a source the vendor never names. Open a demo account to try the platform risk-free, then fund a live account when you're ready. Trading carries risk.
