' Collabora / LibreOffice Basic port of the ONLYOFFICE custom functions.

'
|
|
' UPDATED 2026-07-23: STOCKPRICE / STOCKTIME (Finnhub) removed.
|
|
' Finnhub was dropped because it has no historical price coverage, which is
|
|
' why stockproxy (NAS08) was built in the first place. FUNDPRICE already
|
|
' works for any ticker stockproxy knows about, fund or stock, so it now
|
|
' doubles as the equity price function. FUNDTIME replaces STOCKTIME and
|
|
' returns stockproxy's "resolved_date" field.
|
|
'
|
|
' NOTE: resolved_date is a DATE (YYYY-MM-DD), not a time-of-day timestamp.
|
|
' Finnhub's old STOCKTIME gave true time-of-day resolution; this does not.
|
|
' If intraday precision is ever needed, stockproxy's /current endpoint
|
|
' would need a real timestamp field added on the backend side.
|
|
'
|
|
' HOW TO INSTALL IN COLLABORA:
|
|
' 1. Open the sheet in Collabora (collabora.kingdezigns.com).
|
|
' 2. Tools > Macros > Edit Macros (opens the Basic IDE).
|
|
' 3. In the tree, find "<Your Document Name>" (NOT "My Macros" -
|
|
' you want this stored IN the document so it travels with the file).
|
|
' 4. Right-click "Standard" under your document > Insert > Module.
|
|
' 5. Paste this entire file's contents into the new module.
|
|
' (Or, if StockFunctions already exists, replace its contents.)
|
|
' 6. Fill in PROXY_SECRET() below with the real value if not already set.
|
|
' 7. Save the document (Ctrl+S). Macro security must allow this
|
|
' document's macros to run - if prompted, allow them.
|
|
'
|
|
' USAGE IN CELLS:
|
|
' =FUNDPRICE(D4)
|
|
' =FUNDPRICE_HIST(D4, TEXT($B$3,"yyyy-mm-dd"))
|
|
' =FUNDPRICE(A5) <- replaces old =STOCKPRICE(A5)
|
|
' =FUNDTIME(A5) <- replaces old =STOCKTIME(A5)
