I stepped out of the room to go make a cup of tea and it had dropped while I was out of the room. I tried setting up stop losses on my trades before and just yesterday the price blew through three different trades. Then I had to cancel the stop losses before I could sell them, so I was trying just to watch these all. I think the mistake here was actually trading in the pre-market. I should just do as Tim Bohen says, "wait til 9:45am."
