Worked example

For example, with account size of ₹1,000,000, risk per trade of 1%, entry price of ₹100 and stop-loss price of ₹95, the position size (shares) is 2,000.

Inputs used
Account size ₹1,000,000
Risk per trade 1%
Entry price ₹100
Stop-loss price ₹95
Results
Position size (shares) 2,000
Amount at risk ₹10,000

Frequently asked questions

Divide the money you are willing to risk by the per-share risk (entry − stop). Risking 1% of 10,00,000 with a 5-point stop allows 2,000 shares.

Risking a small fixed percentage, often 1–2%, protects your account from a string of losses and keeps you in the game.

It is the most you would lose if the stop is hit — your account size times the risk percentage.

For precision, allow for brokerage and slippage, which slightly increase the real loss if the stop triggers.
