Nothing here alleges misconduct by any exchange, clearing house, index administrator or firm named, and nothing here is a view on the merits of any listed contract. Margin figures are Kinetic Alpha’s reconstruction of a published methodology applied to public price histories; they are not Nodal Clear parameters, the clearing house has not published requirements for these contracts, and any figures it does publish should be taken over these. Contract specifications are described as announced and are subject to change. Power series are day-ahead settlement prices from ERCOT and PJM and spot gas from EIA; the compute series are public index prints and posted-rate medians, several of which are short, and the monthly compute correlations rest on eight observations while the quarterly rest on five to nine. The offset engine uses a simulated compute index calibrated to a disclosed volatility rather than a traded history, because no such history is public. Research and education, not investment advice.
