Defined as 6 W the normal market size ( NMS). Where a trade of this size is completed, it must be reported into SEAQ under the usual deadlines. However, whereas most trades are then displayed on the screen to give information to investors, display of trades in excess of the maximum publication level are usually delayed for 60 minutes. This gives the market maker who has carried out the trade the opportunity to cover his position in the stock. Dresdner Kleinwort Wasserstein financial glossary
