Frequently Asked Questions

FXOptimize is a portfolio optimizer for traders running multiple Expert Advisors on a single MT4 or MT5 account. You upload your backtest reports and the simulator replays every EA chronologically on one shared balance — with real lot scaling and stacked drawdowns — so you can see which combination actually performs best together.

It also includes Pass Lab, a research tool that estimates your backtest pass rate against eight propfirm challenges with 95% bootstrap confidence intervals.

Most other tools merge trade lists — they stack profits and losses without modeling shared-balance dynamics, so simultaneous drawdowns are invisible. FXOptimize replays every entry and exit in real time order on one shared account, so when two EAs lose at the same time the drawdowns compound the way they would live.

It is also web-based (no install), 100% client-side (your files never leave your browser), and has a free tier. See the full breakdown at FXOptimize vs QuantAnalyzer.

No. FXOptimize is a no-code tool — you upload backtest HTML reports from MT4 or MT5 and the analyzer does the rest. There is no scripting, no Python, and no spreadsheet wrangling. If you can export a backtest from MetaTrader, you can use FXOptimize.

FXOptimize accepts MT4 and MT5 backtest reports in HTML format — the standard output of the MetaTrader Strategy Tester. Both single-currency and multi-currency reports are supported.

We do not currently support MT4/MT5 chart exports, account statements, or third-party formats. If you have a use case that needs those, email [email protected].

Yes. The /demo page runs a full FXOptimize analysis on a pre-loaded synthetic 5-EA portfolio — Pareto frontier, 17 risk metrics, Monte Carlo, Pass Lab — with no signup, no credit card, and no upload required. It is the same engine that processes real portfolios, just with sample data so you can explore every feature first.

The Free tier gives you 3 portfolio analyses per month with the Pareto frontier, balanced portfolio profile, and the public Pass Lab badge — permanently free, no credit card. Paid tiers unlock unlimited analyses, the full Research Note narrative, Monte Carlo with 1,000 simulations, the correlation matrix, What-If lot multipliers, Sync (live MT4/MT5 tracking), Drift Watch, and shareable URLs.

See the full tier comparison at /app/pricing.

No. The price you see on /app/pricing is the price you pay — Free is permanently free, Solo is $39/mo or $299/yr, Studio is $99/mo or $899/yr, and Lifetime Founder is a one-time €399 (capped at 200 seats). VAT is added at checkout where legally required and shown clearly before payment.

We do not run upsells, paywalled features inside paid plans, or per-seat add-ons.

Yes. Solo and Studio are month-to-month or annual subscriptions you can cancel anytime from your billing dashboard — no phone calls, no retention scripts. If you cancel mid-cycle you keep access until the end of the period you paid for. Lifetime Founder is a one-time purchase, so there is nothing to cancel.

Solo ($39/mo) is for individual traders: unlimited analyses, full Research Note, Monte Carlo, Pass Lab, Sync 1 live account, shareable URLs, PDF export.

Studio ($99/mo) is for traders running multiple accounts and EA developers who want a public profile: unlimited multi-account Sync, public /u/{handle} profile, Workspace cockpit, walk-forward optimization, white-label PDF, and read-only API.

Lifetime Founder (€399 one-time, capped 200 seats) is permanent Solo-tier access plus a Founder badge — first come, first served. Full breakdown at /app/pricing.

We offer a 14-day no-questions-asked refund on Solo and Studio subscriptions — email [email protected] with your invoice number and we issue the refund within a few business days. The Lifetime Founder tier carries the same 14-day refund window.

EU customers have additional statutory withdrawal rights under consumer law; we honor those without making you fight for them.

Pass Lab currently runs against seven major propfirms with verified rule sets: FTMO, FundedNext, FundingPips, FXIFY, Goat Funded Trader, The Funded Trader, and The5ers.

Each firm has its own walk-forward window length, drawdown rules, and minimum trading requirements baked into the engine. We also support FTMO 1-step as a separate variant alongside the standard 2-step challenge. See /blog/pass-lab-methodology.html for the full methodology.

Pass Lab returns a 95% confidence interval for your backtest pass rate, not a single number. The lower bound is the bottom of that interval — the conservative end. We rank firms by the CI lower bound, not the point estimate, because it is harder to game and more honest about uncertainty.

A firm with a wide CI like [40%, 95%] looks great on the point estimate but is statistically less reliable than a firm with [55%, 90%]. We recommend on the lower bound, not the best case.

No. Pass Lab is a research and analytics tool — it computes a backtest pass rate from historical data, not a forecast of live trading. Real accounts have slippage, latency, broker-side execution differences, and live market dynamics that backtests do not model.

Use Pass Lab as a comparison tool to find which firm best fits your portfolio, not as a guarantee. Backtests show what did happen — never what will.

We track the seven supported firms and update Pass Lab when their published rules change — for example, FundedNext's 2026 XAUUSD leverage cut and The Funded Trader's switch to unlimited-time challenges are already reflected. Major rule changes get a release note in the blog and a banner on the affected calculator page.

If you spot a rule we have missed, email [email protected] and we will fix it within a few days.

FXOptimize analyzes backtests and gives you a research view of how a portfolio could behave — but per CFTC Rule 4.41, hypothetical and simulated results have inherent limitations and do not represent actual trading. The Sync feature lets you mirror your live MT4/MT5 account into the dashboard for tracking, but FXOptimize does not place trades, manage your account, or guarantee live performance.

Past backtest behavior is not a forecast of future live results. See the full CFTC 4.41 disclaimer.

Yes. Backtest analysis runs entirely client-side — your MT4/MT5 HTML files are parsed in your browser and never uploaded to any server. For features that do need a server (Sync, account, billing), we use Supabase with at-rest encryption and our application data lives on EU servers via Hetzner in Germany.

We are GDPR-compliant and you can request export or deletion at any time. All emails go to Frederik Baunsøe directly at [email protected]. Full details at /privacy.html.

No. Backtest files are processed in your browser and not uploaded to any server, so we have no backtest data to sell. We also do not sell, rent, or share account or contact data with third parties for advertising or marketing.

The only data leaving our infrastructure is the bare minimum for billing (Stripe), transactional email (Resend), and self-hosted privacy-first analytics (Umami) — see /privacy.html for the full list.

Email [email protected] from the account address and we will delete your account, profile, sync history, and any stored portfolios within 30 days as required by GDPR Art. 12 — usually within a few business days.

You can also export everything we hold on you as JSON in the same request. There is no retention period after deletion: your records are removed from production and from backups on the next backup-rotation cycle (within 30 days).

Our application servers run on Hetzner in Germany (EU). Static assets are served via Cloudflare's global CDN. Supabase, our database and auth provider, is also configured in an EU region.

No FXOptimize service routes user data through US-only infrastructure for storage.

Almost none. We run Umami, a self-hosted privacy-first analytics platform that does not use cookies for tracking — and even Umami is gated behind explicit consent via the cookie banner. Strictly necessary cookies (session, auth, CSRF) are used only when you sign in.

We do not run Google Analytics, Plausible, Facebook Pixel, or third-party advertising tags. Full breakdown at /privacy.html#cookies.
