## Position Sizing Errors

Position sizing errors involve allocating too much or too little capital to a single trade, leading to either catastrophic losses or suboptimal returns. In the context of derivatives, where leverage is common, improper sizing can lead to rapid account depletion.

A position that is too large increases the impact of a single loss on the total portfolio, while a position that is too small fails to contribute meaningfully to growth. The optimal size depends on the trader's conviction, the asset's volatility, and the overall risk management constraints of the portfolio.

Many traders make the mistake of sizing based on a gut feeling rather than a mathematical model. Proper sizing involves calculating the risk per trade as a percentage of total equity and adjusting for the probability of success.

It is the most effective way to ensure longevity in the market.
