I have been through a few, but here is the basics of my current structure which may change in the near future due to OPM.
Broker Accounts: Amount required to cover multiple time frames (positions maxed) plus my potential statistical draw down for two weeks.
Bank Account (specifically for trading): Revenue is moved over from my broker accounts every two weeks. If a loss occurs, the account is replenished and triggers a detailed personal audit to ensure that it has statistical merit. All trading expenses are paid from this account. Decisions to increase or decrease size is based off of this account.
Personal Account: As long as my trading bank account (not broker accounts) is in good standing and above required figures, I am paid every two weeks. Adjustments are made quarterly if needed.
As always, this most likley will be different due to ones strategy, goals, funds, personality, etc. The one thing that should not change is a well thought out plan/system with defined rules.
