U know, my TA sucks. So, here is my guess, DANG can go as low as around $9 to show some life, but during the last couple days, volumn picked up. So if I were you, I may set up my $15 lot's stop at high $13. The lot of $18 or $20 need some magic and luck and get even in short term.
don't worry, we all have been through this. the key is learning from your mistake and then you can get your money back somewhere else. Make usre you really really understand the stock you buy. Otherwise, just trade index.
