Position Sizing Formula
Variables Explained:
| Account Capital | Total trading account size (e.g., ₹5,00,000) |
| Risk % | Maximum percentage of account willing to lose on one trade (Typically 1% to 2%) |
| Risk Per Share | The difference between your Entry Price and Stop Loss Price |
Risk-Controlled Position Sizing Example
To ensure you never lose more than 1% (₹5,000) if the stock hits your ₹475 stop loss, you should buy exactly 200 shares.
Example Input Parameters:
- Account Capital ₹5,00,000
- Risk Percentage 1% (Max risk = ₹5,000)
- Entry Price ₹500 / share
- Stop Loss Price ₹475 / share (Risk per share = ₹25)
Calculated Output Summary:
- Max Cash at Risk ₹5,000
- Optimal Share Quantity 200 Shares (₹5,000 ÷ ₹25)
- Total Capital Allocated ₹1,00,000 (200 × ₹500)
