How the position size calculator works

Our position size calculator incorporates your account balance and risk tolerance (as expressed by risk percentage) to recommend appropriate position size limits on your forex trades. 

Why should I use it?

Forex trading can be a profitable endeavour but also a risky one; failure to account for risk could lead to big losses, or even having your account balance wiped out in a single trade. By building a sound strategy based on carefully considered position sizes, you can seek to capitalise on the volatility of the forex market but also live to fight another day even when a few trades don’t go your way.

What is a position size? 

Position size is the amount or percentage of your total portfolio that you plan to devote to a single forex trade. Setting reasonable position size limits is an essential tool for any forex trader, whether you’re a beginner or a seasoned veteran.
