What is a Position Size Calculator?

A Position Size Calculator is a risk management tool that helps traders determine the ideal number of shares or units to buy or sell in a trade. It uses your trading capital, acceptable risk percentage, entry price, and stop-loss price to calculate the maximum position size while keeping your losses within your predefined risk limit.

Proper position sizing is one of the most important aspects of successful trading because it protects your capital and helps maintain consistent risk management.
