Is it permissible to trade prop-firms like topstep and is trading futures and forex in general allowed in islam. Please look into prop-firms and give a detailed answer In Sha Allah. Assalamualkim.

I do not know what Topstep is, but regarding what you have asked generally, all three are forbidden, and Allah knows best. However, you should know that when you are asking for a specific thing, you need to provide details. If you are just asking generally, then yes, they are forbidden because they include gharar and usually riba. There is a risk—or more accurately, there is no real possession like qabd (acquisition)—and in some cases, there is even gambling.
