Tiered Plans

 Please noteImportant: currently the $monthlyVolume variable in the formulas below includes volume across ALL types of securities (e.g. equities, options and futures volume would be combined).  This means that the formula will probably not function as intended if more than one type of security is traded in an account.

Order Quantity Tiered Plan (Per Order)

This plan is designed to charge a fee based on the filled quantity of a single order and therefore does not reference the $monthlyVolume variable.
