Depends on country, depends on capital and assets you want to trade etc .
If you use Tradovate for your live account (as I do), it's easy to copy trade between live accounts and prop firm accounts. Both Tradovate and AMP Futures are a bit shit but they are cheap on margin requirements and more or less work.
There are lots of others - really depends on your needs.
If you mean that you want to trade Gold futures on COMEX (GC/MGC contracts) then I believe most prop firms DO let you trade them, through Tradovate usually?

Thanks for sharing this, very useful.
I'm a non-pro individual looking at algo trading on CME micros (MES/MNQ) via Rithmic, so I'm trying to understand how widespread this is.
A few quick questions if you don't mind:
You mention integrations with IBKR and TradeStation. Have you streamed CME futures data via their APIs without being asked for an ILA or any non-display fee?
Are you going ahead with the ILA, and did CME quote you a specific category/amount?
Which parts of the ILA questionnaire push the cost from \~$400 to "thousands"?
Also curious if anyone has heard of Rithmic-based brokers (AMP, Optimus, EdgeClear, etc.) enforcing the same thing.
Thanks!

I went through the exact same phase when I started a couple years back, and TV's paper trading is honestly way more useful than any demo account from a broker. The charting tools are solid enough that I still use them daily even now with a real account, though I do keep a separate DOM from my broker open on a second screen for execution. For futures I'm with AMP as well, the integration can be a bit clunky sometimes but once you get the settings dialled in it's fine. If you're just learning, don't overcomplicate it early on, the analysis side of TV will cover most of what you need

On NinjaTrader or AMP futures. They have low margin requirements. Try on their simulation account your strategy before switching to live. Godspeed. You can see one of my older post I traded on NinjaTrader with barely $100 and grew the account.

I don't trade prop futures but when you trade normal futures there's a limit to the number of contracts Ninja and other firms supply you at the high leverage. I am not yet at that point but when I am I will be switching to SPX options for safety and the loss of leverage is unattractive. Also recently AMP had issues and traders lost money and AMP won't refund their money, so... Fuck em. Too risky. When trading futures you can blow up a lot more than you have in the trade (initial margin) because of the high leverage. When buying options like SPX calls or puts your max loss is the price you paid for the options. Period. If you don't ever want to owe broker money don't trade more than the cash amount you have in your account. When you are trading hundreds of thousands of dollars or millions of dollars this can be incredibly important. Capping that loss is crucial.
Regarding prop trading I've heard from many people that if you're a winning trader they cut you off and close your account because you keep winning and losing them money. Only in cases like JadeCap or other public traders that are advertising for the prop firms bringing in new clients do they allow you to continuously win. Is this true ?
Have you heard or experienced such things?

Why would a prop firm keep allowing a winning trader to win and lose them large sums of money if that trader is not a public trader that brings in new client money?
