Trade Confirmations and Clearing
GMEX requires their trade participants to approve each of their transactions, and uses ETI sessions via the T7 Interface to manage and process Trade Confirmations and approvals for each transaction completed at the exchange. To support this requirement, the GMEX Gateway connects directly to the exchange and automatically approves all Trade Capture reports received for GMEX trades via the ETI session.
The GMEX Gateway supports trading of the following products:
- IRSIA CMF (Interest Rate Swap Index Average Constant Maturity Futures)
- IRSIA CMI (Interest Rate Swap Index Average Constant Maturity Index) -- Non-tradable. Price updates only.
