I was right on reading the daily charts for both $GRDI and ZAPP but ZAPP was the right choice, it had support at 3.07 and 3 on the daily chart, after breaking out of that resistance zone of 3 from the other day. It comes down to 2.91, 18 cents from the highest buy, I could have gotten it on the way back up for 10%, or risked losing like I did with GRDI. I thought GRDI would be the safer pick, lost anyway. I used 499 shares so I could avoid that message from IB about 500 shares + warning 

 

GRDI popped by 10:45 I was too early.
