Yes I have, I’ve done some research on them before. They’re a trader evaluation firm, not a broker. Their broker is an outfit called EightCap out of somewhere in the Caribbean. They (SurgeTrader) supposedly figured out how to structure things so that a US citizen can trade CFDs (which is normally illegal for retail) through them.
I have no info on whether they’re any good or not, I haven’t used them. However, you do need to understand that EightCap trades all over-the-counter products, nothing is on an exchange. If you ever read Reminiscences of a Stock Operator, CFD brokers are the modern day equivalent of the old bucket shops. That’s not necessarily a bad thing as long as the brokerage is on the up and up. CFDs allow for very precise position sizing, much like Forex. Also, CFDs typically cover a large variety of products: indices, single stocks, metals, energies, crypto, currencies, etc.
All that needs to be weighed against the fact that you’re trading a broker-created instrument that (ostensibly) tracks the underlying asset, not the asset itself.
