How the market works1 Feb 2020 12:37
Between and on news, good or bad,
MMs rarely act as one.
One or two may drive the SP up or down with others looking to price in the opposite direction based on what they think a value should be or suit their trading / position. Just like PI traders they too can be caught out and in effect the MMs can be trading as much against each other.
Ignore fluctuations and fall backs as the only thing that matters is the updates we receive from GGP and NC then what you take from their news.
