Frequently Asked Questions
What is a position size calculator?
A position size calculator tells you exactly how many lots (or units) to trade so that if the market hits your stop-loss, you only lose a fixed percentage of your account — for example 1% or 2%. This is the foundation of professional risk management.
How do I use this calculator?
Enter your account balance, the percentage of your account you're willing to risk on this trade, the stop-loss distance in pips, and your currency pair. The calculator instantly returns the lot size you should trade.
Does it work for crypto and indices?
Yes. The calculator supports forex pairs, cryptocurrency pairs (such as BTC/USD and ETH/USD) and major indices including US30, SPX500 and NAS100.
