Yup, sounds like you did a limit sell vs stop loss? It sold for 15.82 because you were willing to sell for minimum 15.80. But there is stop loss and stop limit that I am still confused about.

Personally I rarely use stop loss / limit, but I think the stop loss changes the order to a market sell after the share price falls below your set point.  Stop limit sells only at your price, so if it gaps below your set point you still own it.
