OSE: TMC Series Ratio 2 Release

August 28

OSE will introduce enhanced functionality for Tailor Made Combination (TMC) entry on options, including support for leg fills with four-decimal precision, on August 28.

To handle the ticking changes for fills on the new products, upgrades are required on the following versions of these applications:

  • OSE Gateway 7.18.8
  • X_TRADER 7.17.75
  • X_RISK 7.17.75
  • TT User Setup 7.17.x
  • FIX Adapter 7.17.94
  • TTAPI 7.17.74
  • X_TRADER API 7.17.74
  • Algo SE 7.17.74
  • Synthetic SE 7.17.74
  • Historical Fill Server 7.17.74
  • Autospreader SE 7.17.74

OSE 7.18.8, along with X_TRADER 7.17.75, also introduces support for the submission of wholesale orders with four-decimal precision.

NOTE: Do not upgrade to OSE 7.18.8 until all dependent applications are upgraded. Client software versions prior to those listed above will crash or become unresponsive if connecting to a Gateway running OSE 7.18.8 software.

After August 28, customers who receive fills with four-decimal precision on TMC leg fills will not see the correct precision displayed unless TT software is upgraded to the versions listed above. For example, a fill at a price which should display as 0.4383 will instead display as 43.83.
