QuantSupport for 64-bit Windows Excel

1. Extract ALL files from this ZIP into a stable local folder.
2. In Excel, open File > Options > Add-ins.
3. Choose Excel Add-ins, click Go, then Browse.
4. Load quantsupport.xll, ExcelDna.IntelliSense64.xll and
   QuantSupport.Ribbon64.xll from that folder.
5. Restart Excel with all three add-ins enabled.
6. Enter =QS.VERSION() to check QuantSupport loaded. Type =QS.EVALUATE(
   to see the function signature and help for the current parameter.
7. Open the QuantSupport ribbon tab. Pricing Contexts and Instruments & Trades
   open the workbook object browser; Inspect Selection shows the object in the
   active cell. Select an object and click Go to cell to edit its source inputs.
   Select an instrument or trade and click Price Selection, or use Pricing in
   the panel. Choose its context and pricer, then run
   PV, Cashflows, Fair rate (with a zero-based leg/segment), or Sensitivities.
   Sensitivities lists risk factors and raw derivatives per unit of each factor.
   Instrument previews use the displayed trade date, side and instrument notional.
   Bond previews also require a CleanPrice, DirtyPrice or ZSpread anchor and value.
   Existing trades use their stored position terms.
   Curves opens curve tables and Instruments & inputs; click Refresh table
   to load a view, then select an instrument
   row to inspect its parameters. Select a pricing context for market levels.
8. Refresh Pricing calculates definitions and delivers background prices and
   dependent result stages, including in Manual mode. Pending values show #N/A.
   Each CONTEXT.ADD contribution belongs to its root context; no PREPARE call or
   explicit input range is needed for evaluation.
9. Reset Memory & Rebuild clears all native QuantSupport objects and calculation
   memory in this Excel instance, then rebuilds every open workbook. This also
   calculates in Manual mode without changing the mode or editing formulas.

Keep quantsupport.intellisense.xml beside quantsupport.xll. If you rename the
QuantSupport XLL, give the XML the same base name. Replacing the add-in requires
the matching XML from the same build or release; extract a new bundle together.

The ribbon and Excel-DNA IntelliSense require .NET Framework 4.6.2 or later. Follow your
organization's policy for downloaded add-ins and trusted locations. Excel for
macOS and Excel in the browser cannot load these XLLs.

Load the add-ins before opening an example workbook, or press Ctrl+Alt+F9
afterwards to rebuild its formulas and object handles.

Without the IntelliSense companion, Ctrl+A after a function name opens Excel's
Function Arguments dialog. Ctrl+Shift+A inserts its argument names.

The browser shows live objects for the active workbook and refreshes when
native objects change while Excel is ready. Normal browsing does not calculate
the workbook; Reset Memory & Rebuild explicitly recalculates all open workbooks.
Valuation dates are market
reference dates; Snapshot (UTC) is the historical observation timestamp, when
available. Neither field is an object's creation time. Use the Setup Guide
button for worksheet construction examples. Creation wizards are not included.
The matching ribbon companion is required for background worksheet results.
It preserves Excel's calculation mode and application-wide RTD throttle.
Use QS.CONTEXT.CREATE and CONTEXT.ADD inputs with QS.EVALUATE; older store
constructors and aliases were removed.
