I am looking to clean the database that I am using (Daily Stock Quotes) as there are lots of old symbols that are not active anymore. I have already
changed the downloader to download only symbols which have shown activity since 2009 however, I still find that older tickers are shown in screeners.
Has anybody cleaned their database already? any tips? The only way I can think of is to do it manually, symbol by symbol, by Symbol > Manage Symbols (Bulk Updater)
> Remove Selected Symbols.
Are there any bulk methods that would remove inactive symbols automatically?
In "Manage Symbols", click on "Select Symbols" and define your conditions.
After that you can select all symbols that meet your conditions and remove them.
Trading financial instruments, including foreign exchange on margin, carries a high level of risk and is not suitable for all investors. The high degree of leverage can work against you as well as for you. Before deciding to invest in financial instruments or foreign exchange you should carefully consider your investment objectives, level of experience, and risk appetite. The possibility exists that you could sustain a loss of some or all of your initial investment and therefore you should not invest money that you cannot afford to lose. You should be aware of all the risks associated with trading and seek advice from an independent financial advisor if you have any doubts.
