Vix had a big rise to the upside today, this move could signal a potential market correction on the stock market. Durring time of financial stress or high volatility VIX rises when it goes up shows as an increase investors fear. Today we have a big GAP to the upisde another gap that look like this one is on february 24 2020 when all the covid lockdowns started and stock market crashed, take a look at that as well.
In general i use VIX like that
