SPY - Potential Downturn

I'm short. Even though volume looks good - it seems OBV is topping out. If you look down to stochastic osc., they're pointing down. RSI is weakening, and the biggest sign I see, MACD crossover may happen in a day or so, we're also pretty high on MACD and this might be the start of a small correction. Or at least a profit-taking pullback.
