Trading Risk Lab is a web-based platform for traders to manage risk before entering positions. It offers interactive calculators for position sizing, risk of ruin, drawdown, risk/reward, and trade planning. Instead of signals, it focuses on modeling potential downsides, like "how much am I risking?" and "how many losses can I survive?" Designed for retail, active, and prop firm traders, it provides fast, practical risk insights with free and premium tools.
