Effective February 12, 2026, LSEG will revise the RICs for all CBOT Reduced Tick (RT) Spread contracts. TT will begin supporting the updated RICs in Production on March 15, 2026. Testing is currently available in UAT.

Example of the RIC change:
Old: AULRTU25-H26
New: AULU25-H26

The new format removes the “RT” identifier from the RIC.

Impacted products:
SI, ZN, UB, PA, ZB, TN, 20U, MGE, 40U, 50U, TWE, DVE, 30U

Starting March 15, 2026, clients must use the revised RIC format when submitting orders through TT.
