All, There is a copy of this document at: http://www.nasdaqtrader.com/trader/tradingservices/marketwatch/tradermanual/tradermanual.stm However, much of it has not been updated since early 2001. Does anyone know if there is a newer version out there? My thought is that learning this manual can give valuable insight into the way the NASDAQ works and could possibly help individual traders by showing them exactly what MM's must do with every trade. Any help is appreciated.
