Bank in a sum of money in RHB Investment Bank Account. You can even do it in Maybank and few others. You need your client code as the bank receiving the money as to key it in to complete the transaction. Then phone the officer in charge in RHB Investment Bank. You can start using the money to buy starting the following day.
You can check yr balance of money in the trust account when you click "account", then click "trust balance". I hope I have answered yr question.

In the long run, we are all dead. Just make a will.
