Risk Management
Why Position Sizing Matters More Than Your Entry
The fastest way to blow up a trading account is not picking bad stocks — it is risking too much on a single trade. Position sizing is the discipline that separates professionals from gamblers.
A simple 2% rule works well for most traders: never let a single losing trade cost you more than 2% of your capital. With a ₹1,00,000 account, that means a maximum loss of ₹2,000 per trade, no matter how confident you feel about the setup.
This calculator translates that rule into a concrete quantity. Once you decide your entry and stop loss, the math is fixed — there is no room to talk yourself into a bigger position. You buy exactly the number of shares that caps your loss at your intended risk.
Over hundreds of trades, proper position sizing is what keeps you in the game through losing streaks. Pair it with a trading journal like StoxMark to see whether you are actually sticking to your plan.
Frequently Asked Questions
What is a good risk percentage per trade?
Most professional traders risk between 0.5% and 2% of their capital per trade. Beginners should stay at or below 1% until they have a proven edge across at least 100 trades.
How is position size calculated?
Position Size = (Capital × Risk%) / (Entry Price − Stop Loss). The formula gives you the maximum shares you can buy while keeping your loss capped at your target risk.
Should I always deploy my full capital?
No. Your position value may exceed your capital when your stop loss is very tight — that would require margin. Always check the "% of capital deployed" output and never use more leverage than your risk plan allows.
Does this work for intraday and swing trades?
Yes. The math is identical for any time horizon. What changes is the width of your stop loss — tighter stops give you more quantity, wider stops give you less.
