Why Do ETF Charts looks like Noisy?

I have noticed that most of the ETF charts look like this from March of 2020 year. Is there any logic behind this? The charts looks very noisy

Market orders during the open most likely. Liquidity is thin in ETFs during market open and sometimes, orders are executed at odd prices.


But the chart looks good last year? Do the prices of the chart will be corrected later?

Volumes of AMO orders going as market orders might have increased.

Why would that happen all of a sudden without any reason ?

Could be some platforms firing a lot of orders in bulk for example.
