Let me tell you about my case.
I'm an IB of Broco.
I reqeusted a withdrawal of my commission (over $3000) one week ago.
My withdrawal has not been processed til now. (I meant that Broco didn't process my request, not a bank problem.)
I think the reason of delaying is that they have so many withdrawal requests or they are going to be another scam broker.
I will update soon with this case.
