Correction over 26 days; bounce for 14; then 9 bars to doom. 1987 crash sequence began a week earlier, on 26 Aug 87. This sequence started on 3 Sep 20; so termination would be expected on or about Mon/Tues 26/27.
The time sequence and chart pattern are virtually identical, down to the number of bars, the retracement level, the 'W' sharky pattern. Oddly enough, 19 October is again on a Monday...
I anticipated a normal correction and resumption of uptrend until now; looking at this pattern unfold is really creepy, sure makes you wonder.
Not investing advice; just an idea and observation. GLTA!
