What is Position Sizing?
When it comes to trading — whether it’s stocks, forex or crypto one thing separates consistently profitable traders from those who blow up their accounts: risk management. And at the core of risk management is position sizing.
Position sizing simply means deciding how much of your capital to put into a single trade. Too big, and one bad trade could wipe you out. Too small, and even winning trades won’t grow your account meaningfully. Finding the sweet spot is what keeps you in the game for the long run.
Here’s how to figure out the right amount to risk per trade, step-by-step.
Step 1: Decide How Much of Your Account to Risk
A common rule among professional traders is to risk only 1% to 2% of your account balance per trade
Let’s understand this with an example:
If you have a 100,000 account and you risk 1%, that means you can only lose 1,000 on a single trade. If you risk 2%, your maximum loss per trade is 2,000.
💡 Pro Tip: Beginners should stick to 1% or less until they’re consistently profitable. This protects you from devastating losses while you’re still learning.
Step 2: Determine Your Stop Loss Level
Before you can calculate your position size, you need to know where you’ll exit if you’re wrong — this is your stop loss level. We’ll understand this in some other blog as to how to figure out that your trade has gone wrong and you must exit out of it. But for now let’s say you’re trading a stock currently priced at 500, and you decide to place your stop loss at 480. Here the risk per share is: 500-480=20. This 20 is the amount you could lose for each share if the trade goes against you.
Step 3: Calculate Position Size
Now, it’s time to figure out how many shares you can buy without exceeding your maximum risk. Here’s the formula: Position Size = Maximum Risk Per Trade ÷ Risk Per Share (SL)
Using our example: Maximum risk per trade = 1,000 (from Step 1)
Risk Per share: 20 (from Step 2)
Position Size = 1000 ÷ 20 = 50 shares.
This means you can buy 50 shares, and if the stock hits your stop loss, you’ll lose exactly 1000 — no more (This amount will only change in case of any Gap-ups or Gap-downs in the market).
Why Position Sizing is Crucial
Without proper position sizing, emotions take over.
- Too large a position = fear and panic when price moves against you.
- Too small a position = frustration because profits feel meaningless.
Position Sizing Calculator
I’ve uploaded a sample position sizing calculator to help you figure out the quantity to buy for a trade. You can use it to calculate the quantity based on the amount of capital you’re willing to risk on that specific trade. As a rule of thumb, try not to invest more than 10% of your total capital in any single trade.
Final Thought
Position sizing isn’t just math — it’s discipline. By sticking to a fixed risk percentage and calculating your position size before every trade, you protect your capital and give yourself the staying power to grow steadily.
Remember
Your number one job as a trader is not to make money, but it’s to protect the money you already have. Profit will automatically follow.
