Test before you trade.
Build a rule, backtest it with costs, check it holds up.

Rules you can read.
Blocks for entries, exits, stops, targets and risk. The lab writes the rule back in plain language, so you can check what you built.

Get the highlights.
Costs and fills you choose.
Spread, commission and slippage. Contract size, lot steps, swap and margin. Four fill models for the bar that touches both stop and target.
Settings that hold up, or not.
Training and test periods, a walk-forward run, the deflated Sharpe ratio and the probability of backtest overfitting.
Same inputs, same result ID.
Every run gets an ID from the rule, the data and the settings. Export the run and anyone can check it.

Thirteen templates.
Trend, pullback, breakout and volatility-targeted rules to start from, each with its sources.
Checked against MetaTrader 5.
The engine is compared trade by trade with the MT5 Strategy Tester, and recomputed by a separate reference implementation written from the rule specification alone.
Backtests and simulations are hypothetical and do not reflect actual trading. Past performance is not indicative of future results.
