## Interactive Quantitative Tools (`/tools`)

- [Listed contract basis & implied repo rate calculator](https://instrumentledger.com/calculators/contract-basis-implied-repo-calculator): Compute theoretical contract fair value, cash-futures basis and implied financing repo rate. Formula: F_theoretical = Spot × e^((r_financing − y_income + c_carry) × T) ; Implied repo = ln(F_market ÷ Spot) ÷ T + y_income − c_carry

Formula: T_session = Remaining_Minutes ÷ (252 × 390) ; 1σ Band = Spot ± (Spot × IV_annual × √T_session)
