How a filed price is stripped to raw

When a filing states its average price “inclusive of fees and expenses,” we divide out an estimated 17.5bp stack for prime brokerage, the desk, market impact and custody. Raw price = filed price ÷ 1.00175. Where a filing says “net of fees” or carries no fee language, nothing is stripped. Our own fees always stay in our price.

The EnsoTrade price comes from our smart routers and smart models, run on the recorded order books of the same days for the same dollars. The routing and the models are proprietary.
