Market Maker Buy Model - MM model, according to which the markup of the asset is performed. Let's repeat the basics: in order to accumulate a long position, the CC uses the pending/emerging sellside liquidity - the supply is absorbed by the demand of the CC. Being in a conditional range where there is not enough liquidity, the CC needs to algorithmically + intentionally markdown the asset to the sellside lq pool → accumulate a long position → by means of an algorithm, deliver it to one of the opposing buyside liquidity pools → realise the previously accumulated volume.
