What you actually get

The variables that decide outcomes

Demo accounts hide friction. ForexThrive surfaces it — so the strategy you validate here is the same one that survives in live.

  • 15+ years of real history

    Replay FX, crypto, and CME-style FX futures with bar-by-bar precision. Speed up time, jump to specific market regimes, hold positions across years.

  • Custom broker conditions

    Dial in your own spread, commission, slippage, leverage, and margin so backtests reflect your actual broker — not a sanitised demo account.

  • Economic calendar overlay

    See exactly which high-impact events were hitting the tapes during your simulation. CPI, NFP, central-bank decisions, in context.

  • Drawdown discipline

    Trading challenges with custom max drawdown limits keep your strategy honest. If your equity tanks, the run ends — like the real thing.

  • TradingView charting

    Use the chart engine you already trade with. 40+ indicators, multi-timeframe sync, custom drawings stored on your device.

  • Zero code required

    No Python, no MQL, no visual flow editors. Click trades, build conviction, export equity curves and trade history when you're done.

How it works

Three steps. No setup.

Open the simulator, pick a market, and start testing in under a minute.

  1. 1

    Build a hypothesis

    Pick a pair, a timeframe, and a setup you want to validate. Mean reversion on EUR/USD H1? Breakouts after London open? Decide once.

  2. 2

    Replay the market

    Step bar by bar or fast-forward through years of history. Manage trades by hand to feel slippage, partial fills, and FOMO without the loss.

  3. 3

    Read the data

    Win rate, expectancy, Sharpe, max drawdown, time in market — every number you need to know whether you have an edge or a story.

Backtest → forward test

One session, from history to live market — on your schedule.

Most tools make you choose: backtest on the past, or forward test on a demo in real time. In ForexThrive it's one continuous session. A game can end up to a year in the future, so the strategy you validate on history keeps running on fresh, unseen data — with one record from the first bar to the latest.

  1. Session startAny date in 15+ years of history
  2. TodayReplay switches to live data, delayed 1 minute
  3. Session endUp to 1 year in the future
Timeline of a ForexThrive session: it starts on any historical date and replays history as a backtest; at the present it switches to 1-minute-delayed live data as a forward test; it can end up to one year in the future.
  1. 01 · Backtest

    Replay history at your pace

    Start a game on any date in 15+ years of data. Step bar by bar or fast-forward — every trade, drawing, and statistic is stored in the session.

  2. 02 · Today

    Hit the present, keep trading

    When the replay reaches today, the same session switches to live market data delayed by one minute. Balance, open positions, and stats carry straight over — your backtest becomes a forward test without starting again.

  3. 03 · Away? Catch up

    Time off is never skipped

    The replay engine only moves while the app is open. Close it for two weeks and those two weeks are waiting when you return: replay them up to today in a few clicks, trading every bar you'd otherwise have missed.

Creating games — with your own dates, instruments, and trading conditions — is part of the prepaid plan. The free tier gives you one predefined game (Feb 22 – May 23, 2022) to try the engine.

Run up to five games side by side — different strategies, or one strategy on different broker settings. See how parallel games work →

No card. No installs.

Start with the numbers, not the narratives.

Open the simulator, replay a market you actually want to trade, and let the equity curve tell you whether you have an edge.
