|SYNTAX||CategoryRemoveSymbol( symbol, category, number )|
|FUNCTION|| Removes the symbol from given category.
Note that for markets, groups, industries 'removing' means moving from given category to category with number zero, since the symbol is assigned always to one and only one market, group, industry and sector. This limitation does not apply to watchlists, favorites, and index categories. When symbol string is empty ("") then current symbol is used.
category is one of the following:
number is a market/group/industry/sector/watchlist number:
The meaning of index parameter is different for GICS and ICB categories - the index for categoryGICS and categoryICB is actually GICS/ICB code. Such as 10 for energy sector or 351010 for "Health Care Equipment & supplies" industry. The codes are fixed even if new classifications are added at some point in the future. This means that you won't need to change AFL codes even if new classifications are added. But it is important to understand that these codes work in hierarchical way. So
GetCategorySymbols( categoryGICS, 10 )
will return all symbols belonging to energy sector, including those in 10101010 - Oil & Gas Drilling sector as well as 10102050 - Coal & Consumable Fuels; for example.
