I currently use Metastock 9, DT5 and Sharescope with EOD data, as well as a Saxo live trading platform. Each has specific features I use.
Unfortunately there are some features in Metastock that aren't in the other platforms that I use to determine trend changes and also specific price points. I'm having some problems with Metastock 9 which is why I'd like to upgrade, but I don't want the latest Metastock which is locked to Datalink.
I'm still using an old copy of Metastock 9 for eod stuff. I like its simplicity, ease of setting up any kind of eod scan and its side by side chart displays. But any charting software would do - a particular brand is not crucial to success in my book..
