Backtesting without the wishful thinking
Describe a strategy in plain English. Backtestify replays it on real market candles and hands back an honest verdict — plus a TradingView strategy you can load.
Free to start. Your first report is a full Pro report.
The improved version must stay profitable on candles the search never saw, or Backtestify reports that no profitable improvement was found. Every outcome is measured, never promised.
Measured, not marketed
How it works
Plain English. We turn it into an exact rule set — nothing is filled in for you.
Real candles, signals confirmed on the close, fills at the next open, costs both sides.
Win rate, drawdown, buy-and-hold beside your return, and a TradingView strategy.

Inside the report
Six panels, measured from the same run. Where a number cannot be measured honestly, the report says so instead of guessing.
One plain sentence on whether the rules held up, with the sample size it rests on.
Your curve next to simply holding the asset over the same window.
Identical rules, identical window, every timeframe you selected, ranked.
Worst peak-to-trough, losing streaks and a Monte Carlo view of the range.
Held out candles the search never saw, plus regime and signal-delay checks.
Pine v6 generated from the rules that were actually executed, not a rewrite.
Improve mode
Paste your current rules. Backtestify tests the original exactly as written first, then searches variations against that same baseline and keeps the most profitable one — or reports that no profitable improvement was found.

FAQ
Public spot market candles from major exchange REST endpoints. Every report names the exchange, the symbol, the candle count and the exact window it used, and incomplete candles are excluded.
No. Backtest mode tests exactly what you describe. If you give no stop or target, the report says none was given and shows how the position was sized instead — nothing is filled in for you.
It only searches the training window. The winner is frozen and then measured once on candles the search never saw, and both numbers are shown side by side.
Yes. Parsing is cached by a normalised prompt hash and windows snap to completed UTC days, so a repeated run on the same day reproduces the same rules, numbers and text.
A TradingView Pine v6 strategy generated from the executed rule set, with the same entries, exits and costs used in the report.
No. Backtestify is a research tool. Results are historical simulations, they are hypothetical, and past performance never guarantees future results.
