In all the wholesale markets (including foreign exchange) if a broker misses a price it should offer to close the deal at the next best price if held to the deal, and must then settle the difference arising by cheque. However, providing management on both sides agree, the difference may be offset against brokerage due. In the absence of mutually agreed arrangement, principals should always be prepared to accept cash settlement, since to do otherwise would put the broker in breach of this code. It is unprofessional for a dealer to refuse to accept a difference cheque and insist the deal is honored; individual brokers facing this situation should advise their senior management who, if necessary, should raise the matter with the management of the client.
