In FX there is no way for the "backed" trader to know that the orders aren't internalized. I don't care what you're told; all of the FX firms are in FX bc it's unverifiable. It's a Ponzi of sorts as they know they can pull in test fees to pay any profitable client as counterparty. The leverage and Draconian SLs make it so.
With futures-prop you can literally watch your one lot fill AH (or not) to test the internalized-order hypothesis.
The vast majority of futures 'prop' (bucket shops) have you indefinitely on the simulator. To my knowledge, only TopStep and Earn2Trade actually gives you a live account eventually. And no, that's not an endorsement of the latter two.
