How to read this tool

Method and limits

A stop price is a planning input

The calculator translates quantity and maximum loss into a trigger distance. After activation, a stop-market order can fill beyond that price, while a stop-limit order may not fill.1

Check whether the provider triggers from mark, index, mid, bid, ask, or last price. Those values can diverge during stress.23
