The AllStocks Folder contains symbols from the NASDAQ, NYSE, NYSEMKT, NYSEARCA and BATS stock exchanges. You can add symbols from any global exchanges if they are not already in the AllStocks Folder. Use "Manage Files" to add new symbols. Not all symbols will be available for download. Use the finance.yahoo.com format.
Other folders are: cboe, etfs, WeeklyOptions and MonthlyDividends. The cboe (Chicago Board of Options Exchange)folder contains securities that have options trading available. These securities can be on any of the major exchanges and are generally safe investments due to the many SEC restrictions put on them. The etfs folder contains Equity Traded Funds, which are also on the major exchanges listed previously. The WeeklyOptions folder contains securities that have options that expire every week. The MonthlyDividends folder contains securities that pay monthly dividends.
