Phsst,
you may add slope characteristics to emphasize the channels.
Take a look at Patterns Recognition in the Library, there is a //
column to get an idea and then calibrate the slopes condition
according to your point of view...
BTW, your opinion on Qs was correct, I stepped in BEAS from 14:00 to
14:30 [with the little help of my friends, Mr Greenspan etc]. It was
nice to see the waken up buyers of the last h. Another round and we
shall check it again...
