Quantity is rounded down so your actual risk never exceeds the amount you set.
The position-sizing formula
Risk management starts with deciding how much you'll lose if you're wrong — before you enter. The maths is simple:
Quantity = (Capital × Risk%) ÷ |Entry − Stop-loss|
The numerator is the rupee you're willing to risk; the denominator is the loss per share if the stop triggers. Risking a small, fixed slice (most pros use 1–2%) means even a long losing streak barely dents your capital — which is what keeps you in the game long enough for your edge to play out.
