1. Select Requests and Configuration > New Request > New Session
2. Under Market, select the applicable market (Eurex ETI or EEX ETI)
3. For Provider, enter TRTSP
4. On the next screen, select an environment (production or simulation). Simulation sessions will be configured in the ext-prod-cert environment. Also, select a business unit and number of sessions. The Market should default to the one selected on the previous screen (EEX or Eurex).
5. On the next screen, select the session capacity type (HF or LF) and installation. Available installations:
   • 1060630-1-5 (LON-Hanbury St 11, Old Truman Brewery)
   • 1060630-6-5 (FRA-Friesstr. 26)

   Once submitted, the pop-up window provides the session ID and password. Note: Write those down immediately or take a screen shot, as this is the only time this information is available on the portal.

   TT Onboarding will approve the session. After approval, the session is ready for order routing.

7. For any issues with the new credentials, contact your TT Onboarding Manager or the TT Onboarding Group: onboarding@tradingtechnologies.com

Sessions Overview

EEX settings are configured per session. The exchange supports the following types of sessions for routing EEX derivatives orders and OTC trades via the Eurex T7 trading system:

• Derivatives - Low-Frequency — Low-Frequency (LF) sessions support lean, non-persistent, and persistent orders. LF sessions have a much lower throughput as compared to HF sessions, and allow all orders and fills to be recovered across a participant's ETI sessions. All exchange-supported order types can be routed through LF sessions.
• Derivatives - High-Frequency — High-frequency (HF) derivatives sessions only support Lean order types. These sessions also have a higher throughput and are designed specifically for automated trading. HF sessions do not have any recoverability mechanism in place for orders or fills. For example, after a session disconnects, it is not possible to inquire or replay the missed executions through an HF session. HF sessions only support GTD orders, so these orders are most likely routed through HF sessions.

  When orders are routed to the exchange, the TT platform sets the “lean order” attribute for ETI sessions. This attribute is a way to improve throughput and reduce latency for high-frequency trading. The exchange processes a lean order without persisting order event messages or broadcasting the messages to all listening ETI sessions.

• Derivatives OTC — A session that connects to the Eurex FIXML interface via SSL certificates for trading OTC (e.g., block trades) on EEX derivatives products via the Eurex T7 trading system.

  Note: Sessions dependent on newly uploaded certificates in the Setup app will only be available after the start of the next trading session.

• Spot Emissions — A session that connects to the T7 derivatives platform for submitting orders and reporting OTC trades for emissions products traded on a Spot basis. Orders are routed and managed by the Eurex T7 trading system.

Persistent Orders

Persistent orders get written to the exchange database and saved during an exchange outage. These orders have the longest round trip time, but are the most reliable. Persistent orders always remain working after a session disconnect, session logout, or exchange outage. GTC and GTDate orders are always persistent.

Non-Persistent Orders

Non-persistent orders have a shorter round-trip time and do not get written to the exchange database. Eurex deletes all non-persistent orders in the event of a session disconnect regardless of the reason: exchange host failure, network outage, exchange event, etc.
