Most of the trades today are likely Brokers like Citadel using HFT apps to flip for micro pennies all day long....they don't like volatility, best for them when it trades nice and tight
Another pet peeve about some MMS that they show 10,000 on the ASK or BID but they have millions to sell at times... Hate when I see 5 MMs on the ASK with all having 10,000 share to sell LOL...
