Hi,

Just wondering, what other FIX 4.2 tags might be specified differently for stock options and stock index futures apart from the SecurityType tag (167) ?

Many thanks.

FIX 4.2:

SecurityType(tag 167) is the main differentiator as you indicated in your posting:

"OPT" for option  
"FUT" for future

Stock options of course will require the use of the PutOrCall(tag 201) and the StrikePrice(tag 202)field.
