brotherant - PBRS is correct. Who are “they” in your question? The mm’s are not involved in the identification of trades as buys or sells.
This whole topic attracts way too much attention here, and is a constant source of heat rather than light. In the long run, buys will equal sells, with mm’s only taking short-term exposure where liquidity is required. The mm’s make their money from the spread, not from changes in the price. Theirs is a flow-business, and they don’t like being exposed as exposure requires reg capital and can easily wipe out the pennies they pick up in fron of the markets steamroller. They are happiest when there is strong two-way volume at a stable price. Most of what you read here regarding mm’s conspiring to “rob” PI’s, to “steal their shares”, to “hold the door open for their mates” etc is whimsical conspiracy theory nonsense from the uninformed, and can be safely ignored..!
