I gave up on Updata because it was costing too much time=£.
They cannot support other feeds, Tenfore in my case. If I crash/freeze, I lose everything. It doesn't save like Indexia does. Also could not draw daily charts. They never resolved that! Also they didn't like me pointing out that TA missed trades that Tenfore and Indexia printed.
Re the rest, IB have a DDE link out I'm trying to work at the moment. I've only got the demo, waiting for fund$ to hit the a/c.
As you say, I don't want to upset the current set up. I'm running Tenfore into Indexia. Tenfore also has it's own charts, though not so comprehensive.
I tried copy/paste as per Updata manual. I might try it into TA as nothing lost! I'm waiting for a reply from IB at the moment. I'm not up on tech stuff.
I'll see how it goes. If I can use IB's feed it solves a lot of problems on feed.
Cheers & good luck
