With the LOD on Friday at 1429.85, There exists a possibility that the correction from 1474.51 is not a single ABC (Zigzag) but could be double or triple zigzag.
With this approach, the index could make another dip to contact with the lower line of the descending channel formed from Sept. 14 (purple) and bounce up to the upper line of the channel before bouncing down again.

The Elliott wave counting on the 15 min chart would be changed like this:
