is IWM going to a flat close with no gap up tomorrow?

Yesterday it was possible a fading the 2 days before gap. One possibility was a bullish debit call spread on TZA (9/19 strikes 15/16) so far it is flat, but TZA keeps always depreciating, by the day, maybe it was better simply to use a bearish debit put spread on IWM.
SPY is losing momentum, IWM as well, …. will they go back down and close at their VWAPs?
