While you are starting out / getting back into it - you could apply for the CME New Trader Incentive Program. Eurex also have an equivalent. Can save you buckets on exchange overhead for the first few years. Tradovate (have said) they would accommodate any incentive program as I am sure most futures brokers would. The savings on exchange overhead could make a big difference and if you smash it during the year, will have no problem covering your overhead and / or finding prop money to work with.
I had known about the Eurex program that targets individual traders that are not automated. I did not know about the CME program. When you read those requirements, it seem to be the opposite of what Eurex is doing. The CME looks like they are targeting prop groups or Arcades, not individual traders.
Does read like that.. I am more familiar with Eurex. Still... Worth investigating. Plus why not just start with a prop / arcade considering the benefits if swinging that many rt a day.
If you are asking me, I would only do that to share technology, not to save on rates. I don't like commingling my capital. But, if they can offer me software I can get on my own, that might tempt me.
