Position size calculator
Work out exactly how many units to trade so a single stop-out never costs more than you decided to risk.
The 1% rule: never risk more than 1-2% of capital on a single trade. Position size is what keeps one bad trade from becoming a bad month.
Risking ₹5,000 at a stop ₹30 away means a max position of 166 units.
Why position sizing beats prediction
Most blown accounts are not a strategy problem, they are a sizing problem. Risking a fixed, small percentage of capital per trade (the classic 1% rule) means no single loss can wreck you, and a losing streak stays survivable. Your edge only compounds if you are still in the game to use it.
Enter your capital, the percentage you are willing to risk, and your entry and stop. The calculator returns the maximum position size that keeps your loss capped if the stop hits. TradeFolie then tracks whether you actually sized to plan, over-sizing after a loss is one of the behaviours it flags and costs in rupees.
