Prove your edge
before you trade it.
Replay historical forex price action bar by bar and trade it with the stops you would use live. Every fill lands at the spread the market actually quoted, so a news-hour blowout hits your backtest, not your account.

Everything a backtest needs, nothing it does not
Bar-by-bar replay
Step through years of price action one candle at a time, with no lookahead, and trade it as it unfolds.
Real spread, honest fills
Longs fill at the ask, shorts at the bid, on the spread the market quoted for that bar, news spikes included.
Performance analytics
Equity curve, drawdown, profit factor, expectancy and R-multiples, broken down by hour, weekday and direction.
Journal and calendar
Every trade lands in a monthly P&L calendar. Drill into any day and turn recurring mistakes into rules.
An assistant that reads your results
Ask how anything works, then let it review a finished session and say what to test next. It never predicts a market.
Session-based workflow
Isolated sessions per pair, period and balance, with timezone-aware timestamps and saved chart state.
Real bars, with the bid and ask that were quoted.

Three steps from idea to evidence
- Step 1
Create a session
Pick a pair, a historical date range, a starting balance and your timezone. Each session is an isolated experiment you can return to any time.
- Step 2
Replay and trade
Step through the market bar by bar and place orders with the stop, target and size you would use live. Longs fill at the ask, shorts at the bid, on the spread recorded for that bar.
- Step 3
Review the analytics
Equity curve, drawdown, expectancy and a trade-by-trade journal show whether the edge is real, before a cent of live capital is at risk.

Not a broker, no signals
Optimus is a testing tool and nothing else, so it has no stake in how often you trade.
Is any real money involved?
No. Optimus is a simulator: it replays historical price data and fills your orders against it. It is not connected to a broker, no order ever reaches a market, and there is nothing to fund. What you risk is your time, not your capital.
What makes the fills different from replaying a chart myself?
Every historical bar carries the bid and ask that were actually quoted on it, and your orders fill at that spread — longs at the ask, shorts at the bid. Most manual replay assumes one price, or a flat spread that never widens. That flatters entries at exactly the moments real spreads blow out. Note that slippage, commission, swap and intra-bar spread changes are not modelled, so a live account will still differ.
Which pairs and how much history are available?
EURUSD, GBPUSD, NZDUSD, USDJPY and XAUUSD (gold) with one-minute candles from Jan 2019 to the present — over 7 years each. All of it is aggregated into nine timeframes from M1 up to monthly. The exact bar counts and date ranges are shown in the data section of this page, read live from the database. More pairs are added as their data is imported and verified.
What does it cost?
Nothing, during early access. Sign in with Google and you have the whole product: twenty backtesting sessions, every pair we carry, the full history with no date-range cap, the replay workspace, the trade journal and the complete analytics set. No card is asked for and there is no plan to choose.
Will it stay free?
Paid plans will come once early access ends, and we will say so on this page and in the dashboard well before anything changes. Sessions and journals you build now are yours and stay with your account either way.
Is Optimus a broker or a signal service?
Neither. Optimus does not execute real trades, does not hold funds, does not sell signals and does not give financial advice. It sells one thing — a place to test your own strategy against real historical prices — so it has no stake in how often or how large you trade.
Do my sessions disappear if I stop paying?
No. The sessions and trades you created stay in your account and stay readable. The Starter limits apply again to new activity, so you keep your history rather than losing it.
Do I need to install anything?
No. Optimus runs in the browser and you sign in with a Google account, so there is no download, no platform plugin and no password for us to lose.
Who can see my backtesting data?
Only you. Every session, trade and journal note is bound to the account that created it, and each request is authorised against that ownership before any data is returned. We do not sell personal information and we do not use your backtests to build anything shown to other users.
