These are the support levels I'm watching, ~2115, ~2000, and ~1800.
2115 is a very important level imo. When it broke above it I had to suspend my bearish expectations. A break back below it turns the bear alert back on. when you consider what a joke this election is and also that there is now reason for the Saudis to dump, and deutsche bank is rekt or something like that... the idea of a major market downturn isn't that crazy. I'll try to link to a chart I saw not too long ago showing how the market normally tops at the change of presidents. Also this is the complacency point on the wall st cheat sheet. Also the dollar looks bullish to me, see other chart.
Based on the technicals, this is an ascending wedge pattern, that typically breaks down, the Daily RSI lends some support to that notion, showing a bearish divergence.
