## Add-on scripts are used for adding functionality to the platform by allowing custom code to be triggered manually from its trading tools. 
## Common use-cases include sending orders, sending basket orders, exporting data to files, communicating with social media and running automated processes.

    ## YOU MUST SET A PARAM TAG FOR EACH PARAMETER ACCEPTED BY THIS FUNCTION.
    ## ALL PARAM TAGS SHOULD BE SET IN THE 'OnInitialize' REGION, RIGHT ABOVE THE 'OnInitialize' FUNCTION.
    ## THE ORDER OF THE TAGS MUST MATCH THE ORDER OF THE ACTUAL PARAMETERS.

    ## REQUIRED ATTRIBUTES:
    ## (1) name: The exact parameter name.
    ## (2) type: The type of data to collect from the user:
    ## Set to "Integer" when the data type is 'int'
    ## Set to "IntegerArray" when the data type is 'int[]'
    ## Set to "DateTime" when the data type is 'long' (The 'long' data type can only be used for date/time representation)
    ## Set to "DateTimeArray" when the data type is 'long[]' (The 'long' data type can only be used for date/time representation)
    ## Set to "Boolean" when the data type is 'bool'
    ## Set to "BooleanArray" when the data type is 'bool[]'
    ## Set to "Double" when the data type is 'double'
    ## Set to "DoubleArray" when the data type is 'double[]'
    ## Set to "String" when the data type is 'string'
    ## Set to "StringArray" when the data type is 'string[]'

    ## OPTIONAL ATTRIBUTES:
    ## (3) default: The default parameter value is only valid when the type is Integer, Boolean, Double, String or an API Type.
    ## (4) min: The minimum parameter value is only valid when the type is Integer or Double.
    ## (5) max: The maximum parameter value is only valid when the type is Integer or Double.

    ## --------------------------------------------------------------------------------------------------
    ## <param name="profitPercentThreshold" type="Double" default="5" min="0" >The minimum amount of profit in percent a position must have in order to qualify for profit taking. </param>
