How to use the Position Size Calculator

The single most important number in risk management isn't your win rate — it's your position size. Get this right and a 40% win rate can still be profitable. Get it wrong and a 70% win rate can still blow up your account.

The 1% rule

Professional traders rarely risk more than 1–2% of capital on a single trade. On ₹1,00,000, that's ₹1,000–₹2,000 of risk per trade. The Position Size Calculator works backward from that risk amount and your stop loss to tell you exactly how many shares to buy.

Works for every market

Use this position size calculator for Indian equities (NSE / BSE), US stocks, forex (MT4 / MT5), crypto and CFDs. Just enter your entry, stop loss and target — the math is the same.

Plan it. Then journal it.

Calculating position size is step one. Step two is committing the plan and journaling whether you actually followed it. QbarTrade wires this calculator straight into your Trade Planner and Trading Journal.
