This is a project that my trading team and I are conducting. This is 8 of 9 charts (available on Trading View) that searches for clues for an imminent correction by using both June and September 2020 cases. It's a comprehensive overview that connects the charts volatility , trends, divergences, credit, and currency strength.
The bond markets warned of a correction in the stock market a few days before June and September's correction. Bonds ripped to the upside a few days prior to the ES, NQ, and RTY correcting. The previous top and fall back in August 7th was due to the inflation scare by the PPE report.
