Sets/gets the range end, which will be used to formulate the expression request (required).

Range end, represented as Variant

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

• If the type is Date, RangeStart/RangeEnd represent date/time in the user-configured time zone (CQGAPIConfig.TimeZoneCode). Non-timed bar requests process date/time range values with a precision of up to minutes.
• All combinations of Date and integer can apply for these properties, except integer/Date.
• If RangeEnd type is integer, then it represents the count of records prior to RangeStart to be requested, so it must be a negative value.
• If RangeEnd is date, it must be further in time than RangeStart.
