Benchmark S&P500 Correction 'rolls on' in Time......not Price?

S&P500 Weekly Chart @ Close 09/27/2016

Whilst the NDX100 negated its Outside- Down Weekly pattern this past Week; the Benchmark S&P500 remains under the 'influence' of the Indecisive Small BUT potentially significant Reversal Week of 08/19.
The MACD remains on a Sell Signal juxtaposed to the Full Stochastic (incomplete Week) but potentially signaling a Test of the 2193.81 High.

NDX100: Signs of the elusive Medium- Term High?

NDX100 Daily Chart @ Close 09/12/2016

Whilst the Benchmark S&P500 gave it's Sell Signal pre- NFP's; the NDX100 gave both a nuanced Daily Indecisive Sign & then an overt Key Reversal Weekly Chart (Small Caps as well) last week.
Largest 2 Day move since the early 2016 'scare' Jan/ Feb leaves as many Q's as A's post FED commentary that exhibits divergent FOMC Policy views?
Should the overdue Correction play out; Support @ 38%/ 62% retrace of Rally > 4180 resides some distance away from Monday's Close.
