After a significant market upturn, if you pull TradingView and you see this red, don't panic.

Check these major tickers one by one, and look for pullbacks towards recently reclaimed levels--HTF ones are better. What you wanna see is those levels hold their support upon touchdown.

As for de-correlating tickers, you wanna see key rejections off lost levels--aka failed reclaim attempts.

Studying correlation and decorrelation relations between these tickers first is key.

This isn't the complete list, plenty tickers can be added to it.
