## <summary>
## Multi-Symbol Trading Strategy scripts are used for simultaneously trading a group of symbols from a single strategy instance.
## Common use-cases include pair trading strategies, basket trading strategies and dynamic index strategies, all of which need to evaluate multiple symbols at the same time in order to make trading decisions.

## 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 an integer.
## Set to "IntegerArray" when the data type is an integer list.
## Set to "DateTime" when the data type is is an integer representing a date/time.
## Set to "DateTimeArray" when the data type is an integer list representing a list of date/time.
## Set to "Boolean" when the data type is a boolean.
## Set to "BooleanArray" when the data type is a list of booleans.
## Set to "Double" when the data type is a number.
## Set to "DoubleArray" when the data type is a list of numbers.
## Set to "String" when the data type is a string.
## Set to "StringArray" when the data type is a list of strings.
## 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.
