Tick Tables, Point Values, and Product Tables

Overview

TT LME Gateway does not provide point values or tick information in their price feed. For further details on configuring these values, refer to the following section called pMerge.

pMerge

The TT LME Gateway installs with the pmerge.exe executable. During installation, this executable runs automatically to set up and configure the product tables that the TT Gateway uses. Additionally, when you upgrade a TT LME Gateway, pmerge.exe runs automatically to merge pre-existing product tables with any new product tables distributed with the latest TT Gateway software.

Note

Products that are not present in the Guardian product table will not be available in the X_TRADER® Market Explorer.

The only time you must use pMerge manually is if TT distributes updated product information in a customer advisory. TT distributes this product information in a file named TT LME Gateway.pmg.

You can run pMerge in two different ways:

  • From Window Explorer
  • From the Command Window

To run pMerge from Windows Explorer:

  1. In Windows Explorer, navigate to <root drive>:ttbin.run pMerge from Windows Explorer:
  2. Double-click pMerge.exe.

    The Open Guardian product table merge file dialog box appears.

  3. Navigate to the location of the TT LME Gateway.pmg file.
  4. Double-click TT LME Gateway.pmg.

    pMerge creates the new product table. After pMerge completes its tasks, the pMerge status bar displays Finished.

  5. Close the pMerge status bar.

To run pMerge from the Command Window:

  1. Open a Command Window.
  2. At the command line prompt, run pMerge using the following syntax:

    pmerge [<root drive>:ttconfigLME.pmg -e Exchange-Flavor [-q | -v]]

    • pmerge: Runs the pMerge.exe file. If you do not include additional commands, this command opens the GUI. Refer to the procedure called To run pMerge from the GUI.
    • -e exchange-flavor: Sets the Exchange-Flavor of the TT Gateway whose product table pMerge updates.
    • -q: Sets pMerge to run in quiet mode. pMerge does not output informative text in the Command Window when it runs.
    • -v: Sets pMerge to run in verbose mode. pMerge outputs informative text in the Command Window when it runs.

    pMerge creates the new product table. After pMerge completes its tasks, the pMerge status bar displays Finished.

  3. Close the pMerge status bar.

Guardian Product Table

The TT LME Gateway installs with the pmerge.exe executable. During installation, this executable runs automatically to set up and configure the product tables that the TT Gateway uses. Additionally, when you upgrade a TT LME Gateway, pmerge.exe runs automatically to merge pre-existing product tables with any new product tables distributed with the latest TT Gateway software.

Note

An updated LME.pmg file is currently available for download via the TT Customer Portal (Product Downloads | PMerge).

Since pMerge is used to manage the TT LME Gateway's product table, Base Tick should be owned by the Exchange and the remaining columns should be owned by the Administrator.

The following illustrates a populated product table for LME:
