How to Use Position Size Calculator
Position sizing is one of the most critical aspects of successful trading. Our free position size calculator helps you determine the optimal number of shares or lots to trade based on your risk tolerance and capital.
Understanding the Inputs
- Capital: Your total trading capital available for trading
- Risk Per Trade: The percentage of capital you're willing to risk on a single trade (typically 1-2%)
- Entry Price: The price at which you plan to enter the trade
- Stop Loss Price: The price at which you'll exit if the trade goes against you
- Risk:Reward Ratio: Your target profit relative to risk (e.g., 1:2 means targeting 2x your risk)
