These ideas are for SWING trades, not day trades, although the "buy high and sell higher" mindset is also successfully used in daytrading.
YELP: Nice bottoming patterns APPEARS to be in order. Only bullish trade for me on this is if it pushes above $25.55. I will not buy unless that price hits. Learned the hard way that the best way to avoid false breakouts is to take a buy high and sell higher approach.....meaning...if a stock is trading at $8 after a large up day, I wont buy unless $8.30 hits. With this mindset, I've been able to avoid fake breakouts, and prevent myself from getting squeezed when short.
PBMD a while back, this approach saved me from shorting...although I never bought either. Mindset was "If price hits this, its going to go higher and squeeze shorts."
RJET: Another nice bottoming pattern. Not a buyer until it breaks over $7.30s which will lead to a potential run back to $8.50s....if this price fills my Stop-Limit order, I will place another stop loss of $6.90 as that will negate the plan altogether.
