Hi,
Another good use for finding the breakout in the past, would be to
look for a retest of the breakout area with lighter volume and
smaller daily price ranges. In Wyckoff terms this a JOC with a
retest. A low risk area to trade, place stop at support area, either
you are right or you are wrong with little capitol risk.
Dimitris thank you for your help,
Dennis
