Separate fees, half-spread and portfolio cost
Calculate a midpoint-relative spread allowance and explicit charges while avoiding full-spread and basis-point conversion errors.
Read the square-root impact term as an uncalibrated heuristic
Inspect the calculator’s nonlinear participation sensitivity, parameter units and limits without treating its coefficient as an empirical market law.
Measure implementation shortfall without hiding unfilled orders
Use a declared decision benchmark to reconcile executed cost, explicit fees and the opportunity cost of incomplete implementation.
A passive order’s lower spread cost can come with incomplete execution
Compare marketable and resting-order scenarios using fill rate, adverse selection and a predeclared completion horizon.
