Abstract

A stop quantity order (SQO) on a market-traded instrument for a computerized trading system. An order to buy [sell] instrument X is an SQO if, in addition to a limit price, and a stop price, it also specifies a stop quantity SQ. It is triggered by either of the following two conditions: The market'"'"'s best offer [bid] price for the instrument is greater [less] than the stop price, or the market'"'"'s best offer price equals the stop price and the quantity offered [bid] at the best offer [bid] price is less than or equal to the stop quantity. Once triggered, it is submitted to the market as a limit order at the limit price. General stop quantity Orders (GSQO) are similar to SQO'"'"'s, but use two markets, one as a trigger instrument, and one as a trade instrument. An order to buy [sell] instrument X is a GSQO if it specifies a limit price, stop price, stop quantity SQ, a stop instrument Y, and a stop direction SD (bid or offer). It is triggered by one of the following two conditions: The stop direction is “offer”, [“bid]”, and the market'"'"'s best offer [bid] price for instrument Y is greater [less] than the stop price, or the quantity offered [bid] at the best offer [bid] price is less than or equal to the stop quantity, and, once triggered, it is submitted to the market as a limit order at the limit price for instrument X.
