I see there are many threads about this, but it is now 2025, and what prop firms were once "reliable" could turn shady within 6-12 months (Apex here in the US).

In the US, Topstep is the gold standard of reliability; they've yet to pull any funny business, along with Take Profit Trader.

Well, unfortunately, none of them offer Eurex. What propfirm does offer it, and is super reliable like Topstep/TPT?

Liberty Market Investment. I am for some time with them now, and the payouts came without problems. So for now I can recomend them.
