For the most accurate answer, plz go call your bank's remittance officer.
I know for a fact if the company is blacklisted in bnm's database, no matter what they won't let you transfer money with that source. If you transfer using other source like bigpay etc, you cannot receive back to our banking system.
But for example if you say you trade with oanda, tdameritrade, interactive broker, no problem.
You must always remember, forex is an inseparable part of the finance system. There cannot be such thing as forex is illegal. Otherwise your banking and financial system will not work. But because of ignorant people, who can't even differentiate what is a pyramid scheme vs real forex trading, bnm has decided to simply blanket ban all "forex" trading.
Trade with a reputable broker. Even if it is more difficult to open an account, or the fees are more expensive, it is ok. Best of all is to trade those multi instrument brokers like tdameritrade and interactive brokers.
Trading for profit is already difficult for many , why are there still people who wants to be burden with withdrawal uncertainties
Anyone you or other forummers here heard of whoever that have made a reasonably good living from trading forex in this forum entire history.
Some testimonial would be inspiring and helpful.
