New comparison
Copy a finished backtest's strategy and data window, then add the money-management configurations you want to compare.
The strategy, the data window, the balance and the costs all come from this run. Only money management varies between the variants.

Money-management configurations
Each configuration runs as its own backtest and is charged separately.
Start from a preset
Pick a starting point in plain language, then open expert mode to adjust anything.
- There is deliberately no martingale or grid preset here. Increasing size after a loss is zero-expectancy at best and strictly negative once any cap is applied, with catastrophic losses at realistic losing-streak probabilities. The compiler refuses one as well.
- The Larry Williams model is reachable in expert mode at its canonical 10% default — the exact number its own author later disavowed after it nearly ruined him. Offering it is a citation of the literature, not a recommendation of the number.
This configuration sets nothing, so it would run with no money management at all.
