Market makers and algorithms trading

Folks,

Anyone here who understand or recommend on how to get more insight about Algorithms and market makers moving stock price. Past few days I’ve been observing price ladder and feel most of these moves are computer generated and I feel it is largely controlled by automated trading algorithms. is there a indicator to spot algo and market makers trading ?

Also with any news, price goes up within few secs. I believe it would be very difficult for real human to catch up to all these news instantly so what’s the catch here ? Does algo /market makers buy and sell to move prices up higher ?

Getting these insights are helpful and I’m trying to figure out a way to make winning against these algorithms trades to think different way. Do you recommend any source to get more understanding on how algorithms and market makers manipulate or work in the market. Also would be interested to know the sources where I can find real time buying by hedge funds or institutional investors.

Thanks.
