Hi
Yes, that has happened to me sometimes . But in a Reg T margin account. I thought that in a portfolio margin account might be different.
And I thought that all Brokers had this kind of restriction. I remember I asked to @RobertMorse that question months ago. He told me that Wedbush has what they call a leverage limit (GMV/Equity). It starts at 5.56 but it can be raised to 15X. Then I understood that was the same restriction as IB, but with less leverage, but now I think I misunderstood.
The restriction in IB is gross position value must not exceed Net liquidation value multiplied by 30. And @RobertMorse is talking about Equity.
I don't know if it is the same for other brokers ,but in IB Equity with loan and Net liquidation value are two very differents concepts .
It is easy to have a net liquidation value of 10 and an ELV of 100 , so if the restriction in Wedbush is calculated like Gross position value/Equity with Loan that would be much less restrictive than IB.
It would be good to find the answer and know what happens with other brokers, because it can be a motive to change Broker.
thanks.
