Generally prop firms wouldn’t consider someone joining that wanted to trade on markets or exchanges they weren’t already familiar with. The turnover of people coming in to prop firms with grand ideas that don’t end up making money means it’s just not worth their time and effort getting access to various new exchanges, the risk of trading a market they aren’t familiar with etc.
If however you approach them with a successful track record trading a new market and offer to fund the initial risk and setup they will welcome you with open arms as it’s a new way for them to diversify. But I think you would need to have shown in excess of $200k in profits a year for someone to take you on trading a new market.
But if you were looking to join a firm trading traditional markets that’s very different. Entry requirements much lower.
Hmm, $200k annual profits already on own capital
a little big goal before start in prop. firm.
