Backtesting
Backtesting runs your complete strategy - signals plus the trade they execute against historical market data, so you can evaluate performance before risking anything.
Indicator strategy backtesting is included in the 6 Month Signal 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.

Reading the results
Year-wise Returns - performance per year: consistency check across different market regimes.
Max Drawdown - the largest peak to trough decline: the worst losing stretch you'd have sat through.
Strategy Stats - total P&L, number of trades, win rate, average profit/loss, risk-reward ratio, and winning/losing streaks.
Full Report - daywise trade logs, downloadable as CSV, sortable by P&L or day.
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.
