Quote from gptrader:
I almost never hold overnight. My time frames for matching market trends with a stock doing a second pass through the OR is 10 and 15 minutes, as this is usually only valid for the first 1.5 to 2 hours of trading. It doesn't have a good probability if the the market enters the flat time of the day. For market trends, I match a stock against the SPY, S&P e-mini and the appropriate ETF (i.e., if I am trading CHK, I will watch the XLE). Best of luck to you, the key is discipline on this, and the willingness to let the trade ride for awhile. Of course, a trader will recognize a major intra-day direction change and exit with some profit if that happens.
