The most recent supply zones would be at the 23 and 38% retrace of this 3rd wave, which would be the targets. As far as it extended you gotta be careful, may just get a flat to the 23% line. But wave was overextended Could get a lot more. It will depend how this shakes out. It is within a correction right now and it is monday afternoon. But it did break trend line
of a 5 wave, which was an extended 3rd wave, then it went into correction. Can wind up with a flat pattern, which then could extend further and possibly break out of channel for more downside. We may wind up with a short 5th wave up eventually producing a bigger structure which will be for the trend reversal... But that would take time.
