No, IG has "in-house" market, on which they have concentrated all their advertisement and support. So, if you are trading the normal app/web platform, you are a victim of their profiteering.
However, they also nominally have a L2 Dealer, which is supposed to be direct market access. I have been trying to trade using their L2 Dealer for over 6 months, but haven't been successful. Why? Because their installation package is out of date and not working, their support team is clueless (directed by management of course), and there is literally zero visibility of that platform or the possibility of using it. Still, it satisfied the requirement for it to be listed as a direct market access platform!! And they lure customers in...
