AlgoBars
Backtesting software
Free, unlimited backtesting
you can trust
AlgoBars gives every account free, unlimited backtesting. Tests only use data that was known at the time, trades fill on the next bar, and fills and spreads follow each broker's real rules. The same strategy on the same data gives the same result every time. You can test on 10+ years of data, optimize parameters, and import Pine Script, MQL or NinjaScript for free.

What makes the results honest
- No look-ahead
- A value on a bar never uses a later bar.
- Next-bar fills
- Trades fill on the next bar, the way they would in a live account.
- Broker-true costs
- Fill delay, worst-fill rules and spreads can match each broker.
- Reproducible
- The same script, settings and prices give the same result, to the last digit.
