      Floor brokers typically receive orders as follows: a member firm'strading desk telephones large own-account and institutional orders to thefirm's floor booth. The booth personnel contact the floor broker,7 whowalks the order to the post where it is traded. Once at the post, the floorbroker either leaves the order with the specialist or joins the tradingcrowd and bids for (or offers) the stock on behalf of his customer. Usingfloor brokers to transmit orders is difficult, so this method is generallyused only for orders that require special care. The most common instanceinvolves large orders that must be "worked" (exposed to the market bit bybit over time so as not to cause the price to jump too quickly in onedirection), or large trades that are being "crossed."8
