Sizing a forex trade in pips
Forex Foundations
Same formula, pip units
Forex position sizing follows the same core formula as stocks: dollar risk divided by stop distance, just measured in pips and pip value instead of dollars per share.
A worked example
A $10,000 account risking 1%, $100, with a 20-pip stop needs a pip value of $5 per pip to hit that exact dollar risk, which lands close to half a standard lot on a USD-quoted pair.
Don't skip straight to a lot size
Skipping the pip-value step and just picking a lot size that feels right is how traders end up risking far more, or far less, than their actual plan intended, especially when switching between pairs with different pip values.
