several individuals account combined to Advisor Account to reduce commission

Interactive Brokers Advisor Account is combined by several （15 most）individuals account which can be traded separately by individuals. the most important things is all individuals account volume is added up as 1 account ，so when the monthly volume over 1 billion commission decrease. I think it is easy to reach 2 billion and the commission will decrease to an half of standard. Do my plan work？

It's a good idea but I think you'll find they calculate commission on each individual account instead of total volume traded for all accounts.

If you've got an account manager you may be able to negotiate, depending on what your negotiating skills are like

I have asked my manager to confirm that all individual account volume are added up to calculate commission，so it should work. as for the big company like IB ，no exclusion for anyone，all account apply to same commission.
