John M: More importantly was the reverse on April 4th. There were many signs before April fourth that a significant bottom was likely. I was posting on the Crystal Ball forum at the time.
I made the call in advance on April 3rd and also posted some trading opportunities on April 4th real time. There were so many signs one could not post them all, a turn hard to miss IMO. Not only did the NDX (NASDAQ 100 Index) tag the 1990 support line, but it also tagged the support line of its 2000 falling megaphone. In addition, but hardly the least, the COMPX (NASDAQ Composite Index) tagged the support line of its 1974 rising megaphone. That same megaphone was tagged at the resistance line to signal the NASDAQ Comp top in March 2000.
