GDX... Pay Attention!!!

I missed the exit yesterday on GDX at 44.12 (was the close on GDX, and violated intra-day). I did not have my sell target order entered. I'll be exiting first thing this AM, regardless of opening price. If an upward extended issue resets, and you still remain short, you are short based on absolutely no principal to the trade, basically you are then flying blind with a recipe for disaster....
