Only to the point that if I'm going long , I prefer the closing price on the bar to be close to top of the bar and vice versa if shorting. If the closing and opening price create a doji near the end of the bar in the direction I am looking at, then that is a real plus. As far as other patterns, I think they are easily seen afterwards and are too subjective ie they are in the eye of the beholder. Indicators are my preference.
