Does any CTA use IB to trade managed future accounts (client sub-account)? If you do, some questions for you: 1. Do you consider the interest earned in such managed account as part of your CTA performance? 2. In IB, the client sub-account has two accounts: (a) one is an security account governed by SEC (b) another is a future account governed by CFTC/NFA. Can you count the interest earned in security account as part of your CTA performance? 3. In IB account statement, do they separate such the accounts (security account & future account)? 4. If not, how do you separate for CTA performance calculation? Any inputs are appreciated! Thanks.
