FIX supports multiple formats and types of communications between financial entities including email, texting, trade allocation, order submissions, order changes, execution reporting and advertisements.

FIX is employed by numerous financial vendors and has emerged as the favored specification among trading partners. The concept originated in 1992 when several brokers expressed interest in using the fledgling Internet to improve the speed, volume and efficiency of their trading activities.

FIX is owned and maintained by FIX Protocol, Ltd.
