Hi Naresh,

All data found in StrikePrice(tag 202) tag should be in decimal format, e.g. “202=8.50”. There will be no changes to this due to OSI.

The tags that are of concern are MaturityMonthYear(200) and MaturityDay(205). OSI will require the following changes:
For FIX 4.2, tag 200 will have the format YYYYMM and tag 205 will be required.
For FIX 4.4 and higher, the day of the month of the option expiration should be appended to tag 200, making its format YYYYMMDD. Tag 205 should not be populated.

Are you concerned about fractional strike prices due to stock splits?

-Greg
