Backtesting
Backtesting runs your complete strategy - signals plus the trade they execute against historical market data, so you can evaluate performance before risking anything.
Backtesting is included on both Signal Plans: 5 backtests a week (resets every Monday) on the 1 Month plan, unlimited on the 6 Month plan. See Pricing & Plans.
Signals say when - a trade says what
Your signal defines when to enter and exit. To backtest, you must also define what gets traded when the signal fires: which legs (options/futures), how many lots, and any risk settings. This trade definition uses AlgoTest's standard Strategy Builder (the same one used for time-based strategies - you may see it referred to as a "920 strategy" elsewhere; it's just a trade configuration).
The 920/AlgoTrade page itself is for time-based strategies. For signal strategies, you only use the Strategy Builder to define the trade - you never need to activate anything from the 920 page. See the FAQ.
Your weekly quota
The backtest entry point shows "X of 5 Signals backtests left this week" plus the day it resets (Monday), if you're on the 1 Month plan. On the 6 Month plan it shows unlimited.
- A backtest consumes 1 credit only when it completes successfully - a failed or errored run doesn't cost you anything.
- Re-running the same strategy (even unchanged) consumes another credit - there are no free re-runs.
- Because a Signals backtest runs against a connected 920 strategy, each run also uses 1 credit from your separate 920 free-backtest pool (25/week). These two counters are shown separately in the app so a Signals backtest never looks like it ate into your 920 credits, and vice versa - see Pricing & Plans for how the two pools work.
- Running out for the week? You'll see a clear "0 of 5 left" state with two options: wait for the Monday reset, or upgrade to the 6 Month plan for unlimited backtesting immediately.

What to look for
| Metric | Question it answers |
|---|---|
| Win rate + avg win/loss | Does the edge come from many small wins or few large ones? |
| Max drawdown | Could you psychologically and financially survive the worst stretch? |
| Year-wise returns | Does it work across market regimes, or only in one lucky year? |
| Number of trades | Enough trades to be statistically meaningful (not 5)? |

Backtests don't capture slippage, order fills, and execution latency the way live markets do. Always forward test before going live. See why results can differ.
