Position Size Calculator
Size your trade so a stop-loss hit risks only a fixed % of capital.
Risk-first sizing
Professional traders decide how much to buy based on how much they are willing to lose, not on a gut feeling. Fix your risk per trade (often 1–2% of capital) and the stop distance, and the position size falls out.
The formula
Shares = (capital × risk%) ÷ (entry − stop-loss). A tighter stop lets you buy more shares for the same rupee risk.
