WHAT IS IN THE ARCHIVE

1. The book's four workbooks, corrected
   Three_Models.xlsx                  Chapters 2, 4, 5 and 7
   The_Sensitivities.xlsx             Chapters 8 and 15
   Volatility_and_the_Price.xlsx      Chapters 9, 16 and 17
   The_Hedging_Simulator.xlsx         Chapters 12 to 15
   00_START_HERE.md                   what changed is at the end
   Each workbook closes on a Checks sheet: 84 checks in all, every one PASS.

2. Blank_Model_Set/  (new)
   The four workbooks with their inputs emptied (51 in all), for your own
   option: the option itself, and the simulation runs a spreadsheet cannot
   produce. Each Checks sheet counts what is still missing and tests what
   holds for any inputs. The book's figures are in book_inputs.txt: type
   them back in and the book's results come back.

3. Working_Documents.pdf  (new)
   Thirteen printable pages: the pricing record, the closed form built on
   one page, the lattice convergence log, the simulation run report, the
   model comparison memo, the Greeks report with a second path to each,
   the risk report line, the volatility note, the library acceptance
   tests, the hedge log, what the trade paid and why, the rebalancing
   policy, and the desk report line with the questions to ask of it.
   A4, fits Letter.

4. Forty_Questions.xlsx  (new)
   Forty questions across the book, marked by the file as you type.

5. Cases/  (new)
   Case_1_The_Spread_That_Is_Mostly_Noise.xlsx    Chapters 4, 5 and 7
   Case_2_Right_About_Volatility.xlsx             Chapters 13 and 14
   Case_3_The_Frequency_Chosen.xlsx               Chapter 14
   Each case: the note on the first sheet, the model after it, checks at the end.

The files open in Excel, LibreOffice Calc, Google Sheets and Numbers. No macros.
