Approach
We prefer primary sources for formulas and for market facts such as lot sizes and settlement. Interpretation reflects widely accepted practice; where practitioners genuinely disagree — for instance on whether to adjust or close a tested short strike — we present the disagreement rather than resolve it. Where a claim is a rule of thumb, we say so. See Methodology for the model and its limits.
