About this tool

How it works

Divides the chosen account risk amount by the absolute distance between entry and stop prices.

A practical way to use it

See how a wider stop reduces share count while keeping the planned dollar risk fixed.

Use results as a practical aid, and verify important decisions against your own source data and qualified guidance.
