ib is a must have broker for retail. it allows you trade everything you can think of except swap. high margin is a high hurdle to protect beginners.
What are the most important things that the firm needs to offer to you? If you have questions about Ironbeam and what we can offer you please feel free to reach out to me: mike.murphy@ironbeam.com
If you like CQG web-platform then go for it I find the offer among futures brokers quite awful for retail. That's for sure. Everybody now trades ES or NQ. Traders who don't are not in brokers' interest
