Mexem broker for US penny stocks?

Is Mexem a good broker for using Ross Cameron’s technique? I’m asking because in my country I don’t have access to TradeZero, and the other brokers I can use don’t have the small-cap tickers that are used in Ross’s strategy. Or do you have any recommendations for a broker that is not based in the United States but could work? Yes, I know the strategy is quite risky, but I’ve been practicing in simulators, and it hasn’t gone badly for me.
