You can trade shares as well as CFD at IG. You could just use pro real-time as a scanner/level 2 datafeed and trade with any broker.
Oh yes that could work, I trade shares with IG at the moment, and I could just use the PRT features and not actually trade from it. That's looking like my best option. Just need to poke around PRT's packages, maybe see if there's a trial for premium or whatever.
Cheers, getting somewhere here!
