Would your strategy pass a prop firm challenge?
Build your strategy without code, backtest it on 1-minute to daily candles, then replay its trades through FTMO, The5ers or Topstep rules, starting a fresh challenge every week of the data. You see how often it passes, how long it takes and how close it came to breaching, all in Strategy Lab.
Presets
FTMO, The5ers and Topstep rules, ready to run.
- FTMO 1-Step
- FTMO 2-Step
- The5ers 1-Step
- Topstep 50K
- Personal account
Presets are based on each firm's published rules as of October 2026. Firms change their rules, so always check the firm's current terms before you start a challenge.
How it works
Hundreds of challenges, not one lucky start date.
Whether a strategy passes depends heavily on when it starts. The account test starts a fresh run every week (or month) of your data, at up to 6 account sizes, and reports what happened across all of them.
Limits are checked inside every candle on open equity, not just at the close, so an intraday dip that would have breached the daily loss is counted as a breach.
Rules modelled
The rules that actually fail algos.
Phases
Challenge, verification and funded phases.
Profit target and daily loss
Including the firm's own day boundary.
Maximum loss
Static, trailing end of day, trailing intraday, or locked at the initial balance.
Minimum days and time limits
How long a pass actually takes.
Best-day consistency
Whether one big day would block a payout.
Payouts and profit split
What a funded account would have paid out.
Results
Pass rate, days to pass and the deepest dip.
See the pass rate, how many days a pass took, how many challenges you would buy per pass, the deepest dip against the limits, the amount paid out once funded, and how often the account ended below where it started.
Turn on the never-breach guard and Strategy Lab sizes trades down so the account rules are never broken, then shows what that does to the pass rate.

Your strategy, your settings, your trades: Tessera does not pick or change strategies. Not financial advice. Trading leveraged CFDs and forex is risky and you can lose more than you deposit. Backtest and paper results are not future results. A simulated pass rate is not a promise that a strategy will pass a challenge.
