Intraday Position Sizing Calculator
Calculate the optimal position size for your intraday trades based on account size, risk tolerance, and stop loss distance. Protect your capital with disciplined risk management.
⚠️ Risk Warning: Trading involves significant risk of loss. Position sizing controls how much you risk per trade, but cannot eliminate trading risk. Never risk money you cannot afford to lose.

Position Sizing Formula
Risk Amount = Account Size × (Risk % ÷ 100)
Risk per Share = Entry Price − Stop Loss (Long)
= Stop Loss − Entry Price (Short)
Position Size = Risk Amount ÷ Risk per Share
This ensures that if your stop loss is hit, you lose exactly your predefined risk amount — no more. This is the foundation of professional risk management.

📖 How to Use
1
Set Your Account Size
Enter your total trading capital. Position sizing is always relative to your account — a professional trader never risks more than 1–2% of their total capital on a single trade.
2
Define Risk per Trade
Set the percentage of your capital you're willing to lose if the trade hits your stop loss. Professionals use 0.5–2%. Beginners should start with 0.5–1% until they're consistently profitable.
3
Enter Entry and Stop Loss
Input your planned entry price and stop loss. The calculator computes risk per share and divides your max risk amount by it to get the exact number of shares/units to buy or sell.
4
Check R:R Scenarios
Review the Risk:Reward table to see potential profits at different target levels. A minimum 1:2 R:R means your target profit is twice your max loss. Aim for trades with at least 1:2 or 1:3 reward ratio.
