108 has been recently actively vibrating:
It has been 108 years since the Cubs won the World series.
so I figured 108 must also be active in the markets and found this cycle
108 week+/-1 wk Cycle: 8/27/10L - 9/14/12H - 10/15/14L - 11/08/16 +/-1 week.
There is also a 350 TD cycle that is due on 11/08/16 +/- week. Of course, all the fixed cycles can and do expand or contract, so the Low could already be in today 11/4, but there is a real election angst that should cause choppiness to lower into 11/8.
