## <summary>
## Trading Strategy scripts are used for trading one symbol at a time such that each symbol gets its own strategy instance.
## Common use-cases include momentum strategies, crossover strategies and overbought / oversold strategies, all of which need to evaluate only a single symbol at a time in order to make trading decisions.

## This function is used for accepting the script parameters and for initializing the script prior to all other function calls.
## Once the script is assigned to a Desktop, its parameter values can be specified by the user and can be selected for optimization.

## 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 "Drawing" when the data type is 'Drawing'
## 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.
