Bobby, a stop loss should never be used in the pinks, if a large brokerage firm begins to accumulate a stock they will always have the MM drop the pps to trigger stop losses and get your shares at a discount.
The pink sheets are very different from the big boards, in the pinks the Market Makers determine the bid and ask so they are able to manipulate the stock, so even on positive volume they can drop the price to trigger your stop loss ( that they can see sitting there )
On a big board stock I will set a stop loss but keep it down lower than the amount that I would really like to loose, I use it strictly to prevent a disaster. If you have been fortunate enough to time one where you go up shortly after getting in then you simply set your stop loss where you lock in the profit that you want to be sure and keep.
Be careful when you set one it will ask you if you want it for the day or until you change it, if you set one for the day it will expire at the end of the day, and you can change the stop loss anytime you want.
But it has been my experience in the pink's stay away from stop losses, you will never catch a break.
Hope this helps. Good luck.
