Possible BUY setup IF price Retraces (ELLIOT WAVE)

I'm hoping for price to drop down to as my red arrow as that would mean price was doing a FLAT for the Minor Wave 2 within the C LEG of my Zigzag. If that's the case I'll be buying at the the end of the FLAT structure for Minor Wave 2 and riding the price till it completes all 5 waves of the C LEG of the zigzag.
