Online there are many traders saying their payout requests were denied by Apex on September 20. They claim they did not break any rules. My guess is that Apex doesn't have the money to payout so is forced to deny payouts.
Just stay away. There are more firms now which is great news for the traders. You can shop around and find firms with less predatory rules to trade with. There entire business model revolves around traders failing challenges. Even when you pass the challenge they collect more with "activation fees". Now the same can be said for other firms. But it's best to avoid a firm who will pay you out one week but then request video proof of your entire strategy the next week.
