I am using the default daily and historical downlaoders and repeatedly come accross ticker symbols that are not in my database. Example, at finviz.com has symbols COMP,
UCL, TLS and it says (NASD exchange) however, those symbols do not appear whenever I run my downloads. Can anyone help me ?

Hi Colin

My 2 cents

I guess If your not paying for data, you will need to manage your symbols. I use the ASX and every week new companies are added, companies are removed (delisted, takeovers etc) and companies change names and or Sector/Industries. Meaning once a week, I need to use the relevant web source (mainly the ASX website) to update my database.

Unless people do this a different way?? For NASD symbols, go to the NASDAQ site, then screener and you can download the entire current symbol set in a CSV which includes Sector/Industry/Country, use a spread sheet to format this for importing to Quantshare, then find the appropriate web sources for deleted/changed/new companies and manage your symbols this way.

Just curious, a question to anyone who pays for data, how do you get notified of new additions/name changes/deletions etc?

Cheers
