Free Backtesting Platform | No Account, No Credit Card

London Strategic Edge runs a free backtesting engine at /backtest. You define the rules, the engine replays history and the report shows what the strategy would have earned and lost. Nothing in the flow asks for a card, and the engine runs before any account exists.

Three ways to define a strategy

The strategy builder takes indicator conditions from a form, so no code is involved. You pick the entry condition, the exit condition, the stop loss and the take profit, and the engine does the rest. Manual mode replays the market bar by bar and records the trades you would have taken, so the result measures your discretion. Brue mode runs a script written in the platform's own strategy language, and a script can call a machine learning model trained in the ML studio.

What the report shows

Every run reports the equity curve, the maximum drawdown, the Sharpe ratio, the profit factor, the win rate and a table of every trade. The drawdown shows the deepest loss the strategy carried before recovering. The profit factor divides gross profit by gross loss, so a value above 1.0 means the wins paid for the losses. The trade table shows each entry and exit, which is where a curve that looks good usually reveals the three outlier trades doing all the work.

The data underneath

The engine tests against the same data store that drives the live charts: 16,000+ instruments, daily history back to 2003 on long listed instruments and intraday resolutions from 1 minute. The free plan runs 50 backtest jobs per day and stores 10 reports.
