You can transfer funds between sub-accounts by using the Sub-account transfer module. If your account is not set up for that, please read what to do here.
The Sub-account transfer module can be found here, or by navigating as follows:
Click the menu 
/ 
> Deposits and Transfers > Sub-account transfer
Then select:
- The account you wish to transfer funds from
- The receiving account
- The amount
- Click Transfer
Fees
There is no transfer fee, however a 1 % conversion fee applies when transferring in different currencies. The conversion rate is calculated by using the mid-spread FX Spot rate at the time of transfer, plus/minus 1 % of a conversion fee.
We charge Platinum clients no more than plus/minus 0.75 percent, and VIPs no more than plus/minus 0.5 percent.
Before making the transfer you can always see the conversion rate that will be applied as well as the final amount that you will receive on your sub-account.
