MyForexFunds is one of the better known prop firms out there that offers people a chance to qualify "to trade the firms funds" However there has been accusations of them manipulating spreads and stop hunting among other things to deliberately bust peoples accounts either during their try out (thus keeping the fees charged to test with them and qualify) or shortly after they qualify. Even been accusations of outright Ponzi scheming that traders who did get paid out from the firm were in reality paid out from incoming payments from new customers trying to qualify to trade. The CFTC in the USA and Ontario Provincial authorities froze their accounts towards the end of last week. It's estimated the firm took in $300M in fees from customers and that the funds were spent FTX and Madoff style to buy shit for the owner and upper leadership of the so-called company.
There had been numerous complaints on reddit and some other forums about traders claiming trading results and actual market conditions didnt match outcomes my guess is MFF FAFO that people eventually would call them out to the proper authorities. There are some legit firms out there but they dont promise pie in the sky to traders and they have strict trading rules and conditions in order to qualify with them. MFF wasnt one of those by a long shot.
