The rate of change shows that the worst might be over for now. The index could break above the 0.618 Fibonacci retracement at 2743 and then breakout beyond the 0.786 retracement at 2800 and move higher and higher to around 2830-2835. I modified the "KST" indicator (Know Sure Thing) settings and the result is that the momentum has broken above the zero line, which is bullish.
Long entry: 2719-2720 (open gap area) Target: 2830-2835 Stop loss: 2690
