This too can happen with technicals when you hold for a swing better control size and take loss earlier. This might bounce but I wont be hoping

 

Another gapper was TWTR even though I didnt play gap down can happen with BO rumors or news, it can go any way better to play it safe and size accordingly.

If I hadn`t taken my loss back in 12`s I would have been holding a bagger till date, remeber rules are rules to protect you. Trading is abt risk mangemnt first.
