HFT firms are fully automated. MM is quoting at the bids and asks and getting filled but without price moving 1 tick straight away against you. Now it's almost impossible to accomplish that anymore.

HF trading is yes, almost fully automated otherwise it can't be called HF simply because human brain can't act as fast.

You think MMkers are making money by trying to capture the spread of the underlying when the spreads are near zero across most markets (most popular ones anyway)? Dude, market makers can make money even if the spreads were negative (aka in favour of the client)

I think I can make money using only a DOM. But I couldn’t follow multiple ones. That’s why I would use charts. To keep up with several markets at once. A + is volume profile per price which TT added to their DOM. But I am not a Market Marker.

TT has lost it's edge. HFT has eaten their lunch. It used to be possible to make markets with TT but try doing that now and you will lose your pants.

TT offers Premium Services which are available to all. Some market makers take advantage of these services like TT Prime for Autospreader. Other do not. It depends on their strategy.
