How many shares or lots to trade so a stop-loss risks only what you planned.
This position ties up ₹50,000 — 50% of your ₹1,00,000 capital.
This is an educational calculator, not investment advice — pick a risk-per-trade that fits your own plan. F&O lot sizes are revised periodically by the exchanges on contract review; the autofilled value is a convenience only, so always verify the current lot size with your broker before you trade.
Quantity = (rupees you're willing to risk) ÷ (entry price − stop-loss price). For F&O it's rounded down to whole lots. This caps your loss at the planned amount if the stop is hit.
Many disciplined traders risk 0.5%–2% of capital per trade. This is an educational tool, not advice — pick a number that fits your own plan.
PnL Book records your planned risk and actual position on every trade you import — so you can see whether you sized to plan and how discipline maps to your P&L over time, automatically.
