SPX500: 3-Drive Reversal (Potential 20% Correction)

We have the S&P500 grinding up to all-time highs. We have some bearish divergence forming and a potential 3-Drive reversal pattern. The 161.8 extension of the 1st drive (green) and 1.272 extension of the 2nd drive (red) both come in around 3100 for so confluence. This is where I will be hunting for reversal. My minimum target will be around 2500 for a Running Flat correction. That is a potential correction of around 20%
