The backtesting tool built into your screeners
Backtests built from your screeners: entries, exits, fees and full metrics to judge a strategy on numbers instead of gut feeling.
Before committing a single euro to a strategy, you need to know whether it holds up. Backtesting replays your rules on historical market data and simulates every trade they would have triggered : entries, exits, fees included. In a few seconds you learn what months of live trial and error would have taught you, without paying the tuition.
Here, a backtest is built from your screeners: an entry screener opens positions, an exit screener closes them. What you test on past data is exactly what you will later scan for on the live market.
Configure a complete strategy
A buy signal is not a strategy. The backtest makes you spell everything out: position direction (LONG or SHORT), risk management and fees. Every parameter changes the outcome, and that is exactly the point: measure the impact of your choices before applying them.
- Starting capital and position size as a percentage of equity.
- Stop loss and take profit as percentages, or through a risk/reward ratio.
- Transaction fees as a percentage or a fixed amount per trade.
- Re-entry conditions to decide when a position may be reopened on the same asset.
Metrics that tell the whole story
A flattering win rate can hide a losing strategy when losses run larger than gains. That is why every backtest produces a full scorecard: win rate, total P&L percentage, maximum drawdown, Sharpe ratio, profit factor, average gain and loss, best and worst trades, consecutive win and loss streaks, average holding time : all benchmarked against a simple buy & hold over the same period.
The equity curve shows how your simulated capital evolves trade after trade, while the trade table breaks down every position: dates, entry and exit prices, and why it was closed. Enough to see where the strategy wins, and, more importantly, where it loses.
Compare by symbol and across strategies
Results break down per symbol: a strategy can shine on crypto and disappoint on stocks. You can also compare several screeners head-to-head on the same universe to settle a debate between two variants of the same idea. The free plan allows 3 strategies on your lists, the Swing plan raises that to 10, and the Day trading plan goes up to 50 with full-market backtests.
Every backtest can also generate a list of the tested symbols in one click: open it on the chart and move from one asset to the next from the side panel to review each setup in context.
A backtest is still a simulation: past or simulated performance is no guarantee of future results. Nothing on this page is investment advice.

- GlossaryWin rateThe win rate is the percentage of winning trades out of all trades of a strategy, to be interpreted together with the average win / average loss ratio.
- GlossarySharpe ratioThe Sharpe ratio measures a strategy's risk-adjusted return, by dividing its excess performance by the volatility of its returns.
- GlossaryProfit factorThe profit factor is the ratio of a strategy's gross profits to its gross losses: above 1, the strategy is profitable.
- GlossaryMaximum drawdownThe maximum drawdown is the largest decline suffered by the equity curve from a peak to the subsequent trough, expressed as a percentage of capital.
- GlossaryEquity curveThe equity curve plots the evolution of a strategy's capital trade after trade, and its shape often says more than any aggregate metric.
- GlossaryStop lossA stop loss is an automatic loss-taking exit level, set before entering a position, which caps each trade's risk at a predetermined amount.
- GlossaryTake profitA take profit is an automatic profit-taking exit level, set before entering a position, which locks in the gain when price reaches the intended target.
- GlossaryRisk/reward ratioThe risk/reward ratio compares a trade's targeted gain with its accepted loss, and together with the win rate determines whether a strategy has positive expectancy.
