This is a bull or bear flag on a higher time with the lower time frame forming a so-called ABC correction. You would want to see a good impluse before the bull or bear flag. These set ups obviously aren't as common as plain ole' regular bull/bear flags.
So, if you see a bull/bear flag on a daily chart, drop down to a 60 minute or 30 min chart and see if that flag is really an ABC formation. If it is, then you've got a power buy/sell set up.
The reason this pattern can sometimes lead to a bigger win is because the a-b-c formation tricks people into thinking it's a trend reversal but it's really a trend continuation pattern on the higher timeframe. So, people get trapped and have to bail which obviously just adds fuel to the fire.
