FESC: the derivatives-equivalence workbench
A research demo that finds alternative options-and-forward structures, verifies their payoffs exactly, and compares their estimated implementation costs.
- For
- Derivatives researchers and structured-trade designers
- Worth noticing
- It reduces structures to exact piecewise-linear payoffs over the union of their strikes, with no sampling tolerance.
Field notes
The workbench separates payoff identity from contract identity: structures are reduced across the union of their strikes, while settlement time, fixing, currency, rounding, and multiplier remain material metadata. Its examples include a mixed call/put/forward inventory with three verified alternatives and a forward spread that collapses to dated cash. Cost is calculated independently from equivalence, using bid, ask, and fee inputs; displayed quotes are illustrative rather than executable.
