Update

Here is the short term chart updated with all three scenarios on one chart before FOMC.
The week has started lower before FOMC as expected. The move looks corrective no impulse and the intraday move higher... could be an impulse, but not convincing so far.
So no change - triangle will look perfect with one more push lower with the same size for a-b-c or E of the triangle(green), second most probable scenario move higher has begun(yellow) and impulse lower for C(red)... the problem is there is no impulse.
Now FOMC should deliver something positive tomorrow:)
