Can someone clairfy how the calculation is made or how they think its made?
IB's website describes it in none other than words, and makes no qualms about it being a 'black box' that they define at their own discretion and can change at any time without warning kinda thing.
So, how does one determine whether their portfolio will be charged this fee or be close to getting there?
Is this interpretation correct: Goto risk navigator. Find out maximum of either -30% or +20% loss exposure. Take this number and subtract from net liquidation. If negative, then this amount is charged a fee per day? What rate is this?
