For traders across India, Japan, Singapore, and Southeast Asia, position sizing determines whether you survive the market long enough to become profitable. This calculator is built for Asian traders — whether you are scalping USD/JPY during the Tokyo session, swing trading EUR/USD from Mumbai, or position trading USD/SGD from Singapore. Enter your balance, risk tolerance, and stop loss to get your exact lot size.

Position Sizing for INR and JPY Accounts
The formula is: Lots = Risk Amount / (Stop Loss Pips x Pip Value). For a typical Indian trader with INR 50,000 (~$600) risking 1% with a 25-pip stop on EUR/USD: $6 / (25 x $10) = 0.024 lots, rounded down to 0.02 lots (2 micro lots). For JPY pair traders, remember that pip values differ — USD/JPY has a pip value of roughly $6.70 per standard lot, so your lot sizes will be slightly larger than EUR/USD equivalents.
Position sizing is the difference between surviving a losing streak and blowing your account. You know the formula now. Apply it on a platform that shows your risk in rupees before you click buy.

Asian traders often favour intraday strategies during the Tokyo and London sessions. Intraday trading typically uses tighter stop losses (10-25 pips) allowing relatively larger lot sizes while maintaining the same dollar risk. Swing traders holding positions overnight use wider stops (50-150 pips) and correspondingly smaller lots. The key principle remains: your percentage risk per trade stays constant regardless of trading style.
With micro lots of 0.01, you can risk as little as Rs 8 per pip. That means a $100 account can properly implement 1% risk management. Start small, prove the system, then scale.
Start With Micro LotsFrequently Asked Questions
Convert your INR balance to USD. With an INR 50,000 account (~$600), 1% risk = $6. For a 25-pip stop on EUR/USD: $6 / (25 x $10) = 0.024 lots. Use 0.02 lots (2 micro lots).
JPY pairs have pip values of approximately $6.70 per standard lot. For a $1,000 account with 1% risk ($10) and a 30-pip stop: $10 / (30 x $6.70) = 0.05 lots (5 micro lots).
For accounts under $1,000, yes. Start with 0.5-1% risk. On a $500 account, 1% means $5 risk per trade. This conservative approach helps survive the learning curve common among new Asian traders.
Intraday trades use tighter stop losses (10-25 pips) allowing slightly larger lots. Swing trades use wider stops (50-150 pips) requiring smaller lots. Your total dollar risk per trade should remain the same regardless.
