Quote from trader_XX:
1.) Who actually MATCHES the bid and offers? IF it isn't the specialist as it sounds like everyone is saying, is the best bid and best order matches automatically electronically? If so, is it being matched so that a slightly higher bid is matched with slightly lower ask so that the specialist makes the spread?
Or does the specialist only make the spread if he makes a round turn (he fills his own bid and offer)?
2.) Also, why is hte specialist always required to have a market bid/ask quote if during trading hours it's mainly just bids and offers bieng matched (and therefore his quote is irrelevent since he's not trading, just matching)?
3.) Finally, aren't most trades 'Market orders'? If a market bid and sell order comes in, how does the specialist decide where the market is to match them at? The last trade? In addition, if yhou're not placing a 'market ordre' but are placing a bid or ask, is this normally a limit order or is there another way to bid/ask (cuz i thought limit orders were normally much higher or lower than the market in order to lock in profits, not place competitive bids)?
thanks guys!
