i use stops based on my ball size. If i woke up on a particular day with brass like balls i don't use stops at all. If i see shrunken balls that day i use tight stops. On a serious note its dependent on what you trying to get out of the trade and also how is the market sentiment ( you can get a gauge of the market in the first hour after opening). short plays tight stops, long plays generous stops. Now a days no matter where you hide your stops it will be hit unless you have a great entry price. My stops are based from 0.75-2.25. most times its 1.25 but then all my plays are for a point or 2 points with few getting me 5 points max.
I assume you are trading a stock priced over $500, when risking $2.25?
