Hi @Nicolas

I have done some further testing this time using the spot Dax in PRT linked to IG.com and in Prorealtime Premium with the German Indicies licenced. I thought this would be a way to check that it was not the lot valuers that were throwing things out.

As you can see in the attached screens the same code produces drastically different results

My hope was to back test systems on PRT premium using their advanced tools to execute on IG.com PRT 10.3, is this going to be possible? I don’t know if IG’s altering of spreads means that you can only create reliable systems to trade on IG.com when linked to their data or if there is something that I have not done correctly in PRT premium

Thanks
