Say i'm holding 40 million shares, no ihub peep lol but someone higher in the food chain.
Say you want 3 million shares. Just put in 1 million @Bid and i will sell 1 million when i see that 1 million @Bid. Do this 3x in this case.
Of course they're in touch with each other...the buyer and 'seller'.
Not going into details...other stock but been there in ...done it (as a taker)...you ask and they'll 'feed' you. Without paying more then the daily pps. All you have to do is being in the wright place/privileged group.
ps: some 'groups' do have licensed MM's in their (chat)rooms.
