Instrument When sending the instrument component block in a FIX client request, you can specify the instrument in any of the following methods: By Security ID By Security Alt ID By Security name These methods can be used as follows: You can use the security ID method for all cases.

You can use the security name method for all contracts on all exchanges with the following exceptions. Note that you cannot use the security name method for ICE contracts that use daily, weekly, variable, and undefined delivery terms.
