Post was later deleted by SC. Some rumour/suggestion it may just be the exclusive version of MC that AMP offer, but I have not seen anything official.
I think the 10 cents extra is the cost for the platform you picked. Do you know any one of AMP data feeds can connect Excel sheet in real-time?
You are correct to point that out... with the correction that the .10c is for the CQG execution route, not the platform. It's a CQG fee regardless of platform, free or paid: at least at AMP.
