These scans help find stocks which are behaving in a way that indicates a stalemate between buyers and sellers. That may appear as a very tight daily range or, in the case of doji candlestick patterns, as the open price being very close to the closing price. These can be especially useful to help find trend reversals. So while an "indecision" pattern may be worthless in a non-trending stock, it can be a great warning in a stock that's been trending and may be near a possible support or resistance level. As such, these are good candidates to use in a combo scan.
