>>>>>
>>>>>
>>>>> + GetExtraData now supports two new historical fundamental data fields

>>>>>
>>>>> Sales and EPS historical figures are provided by QP2 on quarterly

>>>>> Since QP2 reports dates for this data only in YYYYMM format

>>>>>
>>>>> Example:
>>>>> Plot(GetExtraData("Sales"), "Sales", colorRed );
>>>>> Plot(GetExtraData("EPS"), "EPS", colorGreen );
>>>>>
>>>>> + "Retrieve" generates more detailed groupings now:

>>>>> index, common stocks, preferred stocks, ADR, warrant or right,
>>>>> mutual
>>>>> or
>>>> investment trust fund,
>>>>> convertible preferred, ETF, Unit - (UIT), certificate, Unit
