Hi, I'm looking for a data source for US stocks for historical back testing of strategies. My main interest is for EOD data. To avoid back testing bias, I would like to get a database that has 1. coverage of dead/inactive historical stocks EOD prices 2. an associated corporate action history / security master 3. CUSIPs so that I can link it to another database 4. Has a data feed like service, e.g. FTP site from where I can download a few files everyday I tried calling esignal and a few other vendors, but most didn't get it when I asked if they carried dead/inactive stock price data or CUSIPs or security master. Esignal sales rep on the phone told me that they definitely don't cover dead securities. please note: I'm not looking for the cheapest solution, but a good retail solution. Preferably less than 5k annually for all the 4 features above. Thanks.
