Their was a nice head and shoulder formation in the afternoon that looked like it was going to lead to lower prices. Then it started reversing into the close. Bet alot of stop were hit causing the rapid rise.
still can cause some very good moves...just as an open or close sometimes (not every single day, but on many) back to the OP topic though, when a lot are trying to get out at the end before market close...sure things are going to get a little crazy.
Oh yeah... I forgot to never test your theories with an actual trade!!! They only work when you have no money at stake!!! I have literally been laughing about this trade all morning. Didn't know exactly how to play it just KNEW that every time it popped or tanked at the close the fade would have paid the next day. Glad I'm still holding!!
