Tick Tables, Point Values, and Product Tables

Overview

Point values and product descriptions are provided via the pMerge file that is distributed with the Gateway. Ticking information is currently received from the exchange.

pMerge

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

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 SFE.pmg.

You can run pMerge in two different ways:

  • From Windows Explorer
  • From the Command Window

To run pMerge from Windows Explorer:

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

    The Open Guardian product table merge file dialog box appears.

  3. Navigate to the location of the SFE.pmg file
  4. Double-click SFE.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:

    Example Running pMerge from the Command Line

    pmerge [<root drive.:ttconfigSFE.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.

    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

Since pMerge is used to manage the TT SFE 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:
