Risk Range and Dynamic Sizing — The AlphaRail Foundry Laboratory

Risk Range and Dynamic SizingAlmost every backtester exposes a single risk-per-trade field and treats it as settled. In a real account risk is a range, not a number: it varies by branch, by conviction, by regime, by how deep the drawdown is, and by how much of the authorised pool is already committed to positions that have not closed. This laboratory models risk the way it actually behaves.This page is rendered from a structured specification file and needs JavaScript to display in full.
