The distinguished feature of those accounts is the presence of subaccounts. Customers with '''FA''' , or '''Master''', or '''Friends and Family''' accounts may notice that when MultiCharts is connected to IB data source/broker with such account type, all subaccounts are constantly changing in IB TWS. There is a reason for this. '''FA'''/'''Master'''/'''Friends and Family''' account doesn't allow any 3rd party software to access all subaccounts at the same time to get updated information about account balance, open market positions, active orders and so on. That is why MultiCharts has to switch them constantly in IB TWS to update info on all accounts.

<div style="background-color: #E3FBE5;">'''Note''': Old versions of MultiCharts may have an issue showing similar behavior '''without''' '''FA''' or '''Master''' account connected. Update your MultiCharts at least to version 8 to fix the issue..</div>
