Dear Users:.We have recently upgraded our sub-accounts system. Updates to our sub-account related features are described below:.1. The maximum number of sub-accounts available is determined based on the tier level of the master account, as described below:. Master Account Tier Maximum Number of Sub-Accounts LV 0 5 LV 1 5 LV 2 5 LV 3 5 LV 4 10 LV 5 15 LV 6 20 LV 7 25 LV 8 30 LV 9 35 LV 10 40 LV 11 45 LV 12 50.2. A type must also be set for each sub-account. There are three sub-account types:All .Futures .Margin ..For example: sub-accounts whose type setting are set to "Futures" cannot be used for margin trading; whereas, sub-accounts whose type setting are set to "Margin" cannot be used for futures trading. Sub-accounts whose type setting are set to "All" have no category restrictions and can be used for all transaction categories..Note: all sub-account types can be used for spot trading..3.
