SPX approaching resistance, potential drop!

SPX is approaching our first resistance at 2817 (78.6% fibonacci retracement, 100% fibonacci extension, horizontal swing high resistance) and a strong drop might occur pushing price down to our major support at 2616 (38.2% fibonacci retracement).
Stochastic (89, 5, 3) is also approaching resistance and we might see a corresponding drop in price should it react off this level.
