Re: mechanics of trading notional accounts within TWS...
You obviously can't just enter bunch orders (or block orders as they are mistakenly called) based on account NAV. You must create an account profile, and enter either allocation percentages or ratios.
Since some CTAs trade their clients accounts with fully automated operations, I am just wondering whether the IB/TWS (or any other platform) can perform required allocation/distribution of bunch/block orders based on the All accounts' Nominal sizes, rather than their NAV sizes.
I assume that Nominal = Actual + Notional + Gains/Losses.
In other words, the TWS platform should be able to calculate and update the allocation %/ratios automatically based on all the Nominal sizes, therefore no human entry by manual operations about allocation %/ratios is required.
