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 by navigating as follows:
In SaxoTraderGO/PRO: Menu 
> Deposits and Transfers > Sub-account transfer
Then select:
- The account you wish to transfer funds from
- The receiving account
- The amount
- Click Transfer. The indicative conversion rate will be shown in the relevant field.
To request a transfer, please select the account you wish to transfer funds from, the receiving sub-account and the amount to transfer, then click Transfer. The indicative conversion rate will be shown in the relevant field.
There is no transfer fee, however, a 1% conversion fee applies when transferring in different currencies. The conversion fee is charged by using the mid-spread FX Spot rate at the time of transfer, plus/minus 1%.
I DO NOT have a Sub-Account Transfer module available on the trading platform or for some reason I cannot perform the transfer.
