Two options:
1. Gap up open then fill gap and make new lows in the morning then start rebounce...
2. Gap down open then start rebounce...
either case prepare to load up ~2120
Next support I can see from chart could be one of these three 2100 (support line from 1810), 2088 (EMA 200DAY), 2078 (EMA 50WK). Due to election process, lots of news/rumors will play out ahead, so this pull back may likely a test before real big drop happens, this should be a short turbulence on the road to me.
this rally will be short lived, at most last to next morning, no rush to jump in short though, let's see how high it can reach today (my guess is <2147)
