the move lower from 1765 area looks very leading diagonal-ish. If this is operable count, another probable dip below 1717 for wave 1, then I would expect a really deep wave 2 retracement, then the bottom should fall out in wave 3 of 1. Look for bullish divergence on stock RSI 1 hour on dip below 1717 to indicate end of 5 of 1.
