A: Fixing: A preset time of day when bids and offers are aggregated and cleared at a published price. Popular fixings are the “ECB fix” at 12:15 GMT and the London fixing at 16:00 GMT. Fixings are used primarily by asset managers. They have a fiduciary responsibility to get their clients the best possible execution and the thinking is the fixing price is the most transparent of the day. The benchmark price is published by the WM Company.
