There are no 'mm' codes these days. What you see on L2 is partial trades. Someone buys 100K shares at a price and the MM fills most of it, then later fills the rest. I've had some of my buys take days to fill. but every partial is listed as a 'trade' on L2. That is the flow of trades, not the flow of complete orders.
