A secondary cross-sectional function, which requests that the primary function be calculated separately for each group of stocks that share the same economic sector name
Calculates the average 100-bar ROC of all stocks in this economic sector and stores it as "EconROC" for each stock.
Requires data with ?EconSect names in each stock record.
Norgate provides these automatically -- use Classification to specify which scheme to request at Import time.
For other data sources you would need to provide them via a SymInfo file.
