Ask experienced traders what matters most and many will give the same answer: not the entry, but the risk. Good risk management won’t make every trade a winner. It makes sure no single trade can knock you out of the game.
Step 1: Decide your risk per trade
Many professional traders risk only a small, fixed percentage of their capital on any one trade — often around 1–2%. The exact number is a personal decision, but the principle is what matters: the amount you can lose is decided before you enter.
Example: with a trading capital of ₹2,00,000 and a 1% risk rule, the maximum loss on one trade is ₹2,000.
Step 2: Place the stop loss where the idea is wrong
A stop loss isn’t a random number. It belongs at the level where your trade idea is clearly invalid — for example, below the support your setup depends on. If price reaches it, the reason for the trade no longer exists.
Step 3: Calculate the position size
Now combine the two:
Position size = Risk per trade ÷ (Entry price − Stop loss price)
Example: you want to buy a stock at ₹500 with a stop loss at ₹490. Your risk per share is ₹10. With a ₹2,000 risk limit, the position size is 2,000 ÷ 10 = 200 shares. If the stop were wider, at ₹480, the size would drop to 100 shares — same rupee risk, different quantity.
This is the key idea: you don’t pick a quantity and hope. You let your risk decide the quantity.
Step 4: Think in risk-to-reward
Before entering, compare what you could gain with what you are risking. A trade risking ₹10 per share for a realistic ₹20 target has a 1:2 risk-to-reward. Traders who consistently take trades with sensible risk-to-reward can stay profitable even if they win less than half their trades.
Common mistakes that destroy accounts
- Moving the stop loss further away once the trade goes wrong
- Increasing size after a loss to “win it back”
- Taking a full-size position on a tip or a feeling
- Ignoring how leverage in F&O multiplies losses
Make it a habit, not a rule you remember sometimes
Write your risk, stop and size in a trading journal for every trade, and review it weekly. That habit is what separates a trader with a process from a gambler with a screen. Risk management and trade planning is a full module in our curriculum for exactly this reason.
