I used the 30-min charts to identify major intra day support levels and decided to put my stop in ROVI below $43.50 and my stop in DTG below $46.88. If these stocks are really strong they should bounce before getting to these levels instead of slicing through.
So now I am in a position where I cannot lose but stand to make small profits on both positions although the profits would not be as large as I had hoped for. In current market conditions, I favor defense over offence for two major reasons. Firstly, with the high levels of volatility it is very easy to get stopped even after being in the profit on positions. Secondly, with earnings bombs dropping all over the place it is very easy for positions to blow up!
So be quick to take profits and not over trade by risking multiples of your usual R. If anything look to risk 1/2 R - 3/4R on trades in stead of 1R - 2R's.
Be careful in this market.
Good luck and good trading!
