Formula
Position Size = (Account * Risk%) / (Entry - Stop Loss). Example: (100000*1%)/(100-95)=1000/5=200 shares. Risk 1K if SL hit.
Position-size formula
Permitted monetary risk = account value × risk percentage. Risk per unit is the absolute difference between entry and stop price. Position size equals permitted monetary risk divided by risk per unit, rounded down so the estimated risk does not exceed the selected limit.
Example: a ₹5,00,000 account risking 1% permits ₹5,000 risk. If entry is ₹200 and stop is ₹190, risk is ₹10 per share and the formula gives 500 shares before fees, slippage and gap risk.
