      However, if the market maker moves to the inside quote and startsbuying shares, for example, then the pitch is "in your ear." This buyer isaggressive, and the size can be assumed to be genuine with relativeconfidence. You will not see this action too often, because market makerswill do their best to hide their intention. In the rare instance that thispattern reveals itself, go with the flow. If the market maker is a seller,try to get short (although this will be very difficult to do if anaggressive seller is downticking the offer and "whacking" the bid). If themarket maker is a buyer, buy. Since he is aggressive, you will have toleapfrog him. You can either split the spread using an ECN, take the offer,or bid above the offer on SNET for a higher probability of a fill. With anaggressive buyer at the inside quote, I would not recommend splitting thespread. Don't be cheap.
