I spoke with Adnan at AxiomaticAI today. he's the kind of guy whom after speaking for 2 minutes you know you're going to go with his work, but you listen to the other 8-10 minutes because he's that interesting.
so, to summarize;
AxiomaticAI is providing MT5 to Ironbeam as well as StoneX (Gain Futures). both are DMA. I had an existing account with Ironbeam which was funded today. I presume I'll get the invoice from Axiomatic tomorrow and hopefully I'll get credentials to try out for Monday shortly after.
You pay a monthly base rate + per-trade fee to Axiomatic. there are three tiers. you can find them on the pricing section of their site.
I will post updates as I have them along with comparisons. Adnan stated that roughly within the next month or two he will be bypassing CQG entirely and connecting directly to the exchanges. so, we'll see.
