Gets/sets the range start, which will be used to formulate the request for a group of instruments.

Range start, represented as Variant

RangeStart and RangeEnd specify the underlying instruments month range, for which data is requested.

Only Date and integer are allowed for types of RangeStart/RangeEnd properties:

• Date values specify the range of contract months starting from the current active instrument month. Values represent date/time in the user-configured time zone (CQGAPIConfig.TimeZoneCode).
  RangeStart must be greater than 0 and RangeEnd must indicate a later date.
• Integer values specify the range of contract numbers starting from the current active instrument.
  RangeStart must be greater than 0 and RangeEnd must be greater or equal to RangeStart.
• RangeStart and RangeEnd must be of the same type.
• If no range (i.e., RangeStart and RangeEnd) is specified, all corresponding instruments will be returned.
