Not sure if this qualifies as the O'Neil extended run, faulty, short base sell signal.

I know that level 3 seminar describes a 2 weeks down 2 weeks up, faulty base top.  Not sure about this shorter three week pattern.

I think that if a stock pulls back more than 12%, it generally needs to put in a minimum four week pattern.  Otherwise it is trying to make new highs from a wide and loose, short, faulty base.

My interpretation of the CAN SLIM rules says that 12% or less declines may qualify as handles or high handles. Otherwise there are substantial sellers and the stock needs a full base pattern before it can get on to making new highs.
