The tag Text (58) doesn't present in all of the messages so the following Business logic will update it everywhere when it is applicable

Business logic configuration:

  • For all messages run the UpdateText.js script

    Code Block
    languagexml
    titleBL_Config.xml
            <Rule Description="Update Text for all messages from all sessions">
                <Source Name=".*" />
                <Action>
    				<!-- ... some business logic ... -->
    				<Script Language="JavaScript" FileName="../FIXEdge1/conf/UpdateText.js"/>
    				<!-- ... some business logic ... -->		
                </Action>
            </Rule>
  • The script checks and updates the value of tag 58.

    Code Block
    languagejs
    titleUpdateText.js
    txt = "UpdateText.js was applied to the message";
    if (isSupportedField(58)) // If it is possible to update field 58
    	setStringField(58, txt); // update the text

2. Save the various message ids and information about parties to the database

The case is useful if a user needs to save a message reference and information about parties for all possible messages passing through the FIXEdge

The example below saves information about

For this example every party entry would be saved as a single row in the table. 

For example, one message with 3 parties would be split and stored as 3 rows in the table.

Business logic configuration:

  • Define database table as ODBC History for FIXEdge

    Code Block
    languagexml
    titleBL_Config.xml
    collapsetrue
    	<History Name="FIXMessages"
                 StorageType="ODBC"

  • Call SaveData.js script  for all message types

    Code Block
    languagexml
    titleBL_Config.xml
            <Rule Description="Save Parties and IDs for all messages from all sessions">
                <Source Name=".*" />
                <Action>
    				<!-- ... some business logic ... -->
    				<Script Language="JavaScript" FileName="../FIXEdge1/conf/SaveData.js"/>
    				<!-- ... some business logic ... -->		
                </Action>
            </Rule>
