No need to complicate this. Clear breakdown signal today. The ascending wedge is broken down on high volumes. There will be a retracement but this market is short until 2136 is broken. Sell if it goes up a bit tomorrow. Incidentally, lots of Fibonacci guys were predicting 2136 to be the top - (don't know how) so there is selling pressure around that level. Many steps below will provide some support on the way down but my target is retest of oct lows around 1816 at the very least.
