Understanding Edge in Trading

Why edge comes before risk management

Risk management protects an edge. It cannot create one. If your strategy has no positive expectancy, sizing it carefully only loses money more slowly. So the first question is not how much to risk. It is whether the strategy makes money at all, measured across enough trades to trust the answer.

That is why this comes first. Once you have evidence your strategy has a real edge, the risk management guides decide how much of that edge reaches your account.
