Abstract

In an automated exchange system means are provided by means of which a market maker can enter a course of action in advance, so that the volume in the orderbook is continuously updated, and where the updating is performed differently with respect to different counter parts. Also, quotes that may result in a trade between Market Makers are hidden for some time before being matched, thus giving the Market Makers a chance to back off. The system employs a function that supports that Market Makers through pre-defined parameters will have new orders generated by the system and that a market maker can act differently with respect to different counterparts. The parameters specify if a Market Maker should add extra volume on an existing price or generate a new order at a worse price. In order to make it possible for market makers to have a very tight spread without forcing them to take larger risks, additional logic is used when matching orders. The algorithm used for this purpose protects the market makers in certain situations and gives market makers the possibility to have a tight spread without taking a large risk. The algorithm also supports that the market makers can take the risk to quote large volumes.

Description

[0001] The present invention relates to a method and a system for increasing the security against undesired matches in an automated exchange system.BACKGROUND OF THE INVENTION AND STATE OF THE ART

[0002] In existing automated exchange systems for continuous trading (dealer market), a simple first in first served model in the matching is commonly used. Thus, if there is a selling price, which is matched by a buying price, the two orders are matched.

[0003] To increase liquidity there are Market Makers (quoters) who are required by the exchange to continuously enter two way quotes. The basic idea is that Market makers must have a two way quote in the market all the time. The quotes (together with ordinary orders) creates a best bid and offer that is sent out as the exchange official price. The best bid offer is used by investors when deciding about buying or selling an instrument. It is in the exchange interest to have as tight spread, i.e. the difference between the selling price and t...
