SPX's momentum is lvl, possible not an ending diagonal after all

Need lower momentum to confirm weakening 5th wave of an Ending Diagonal.

***Contracting ending diagonals should always show
a corresponding decrease in momentum as they
progress towards their culmination. Many small
candles that take a lot of time to gain further
ground is a good sign that an ending diagonal is
indeed occurring. Conversely, strong big candles
within a potential diagonal formation should be
a warning sign that you are probably witnessing
a 1-2, 1-2, 1-2 extension of the trend, and
therefore not an ending diagonal.
