I don't think there's any problem if you mentioned it's from trading though? For me, this is more preferable rather than transacting using local bank option that some broker have such as XM. The reason being is that I notice when doing this local transfer the name of the recipient as well as sometimes the reference of that transaction is 'questionable' because they want to avoid the bank to know it's related to deposit/withdrawal to/from forex brokers. It's borderline money laundering.

In general, if you transfer the money from your bank to broker, then from broker back to same bank, then there is no issue. Because money can trace origin.

Problem start when you bank in to broker using big pay la, or western union la. Then after that from broker send back to your bank. This one money cannot trace sure got problem one. Do it too much and bank negara will call you.

The best is to call your bank's remittance officer and explain your situation. See if it is accepted or not.

What you use your money for outside is none of thier concern. Even if you use it to gamble or forex also it should not be a problem. What bank negara wants to know is where the money come from.
