<p><strong>Position Sizing</strong> is the process of determining the amount of capital to risk on a single trade, typically expressed as a percentage of the total trading account. It's a crucial aspect of risk management that helps traders maintain control over their portfolio and avoid excessive losses.</p>
<p>Position sizing matters because it directly impacts the risk-reward ratio and the potential impact of a losing trade on the overall account. For instance, a 1% risk per trade on a $10,000 account would risk $100 per trade. If that trade loses, it's only a 1% loss on the account, allowing for more trades and potentially more wins to recover. Conversely, a 5% risk per trade could lead to a significant drawdown after a losing streak.</p>
