agrees with the Signal card; "Start analyse" is still there for an on-demand live run
with custom parameters, which does NOT overwrite this cache.
Looked up by the Cockpit Watchlist ticker the cache is keyed on, normalized via the
same yfinance-suffix stripping instrument_service uses elsewhere (EURUSD=X -> EURUSD)
— a quick-added instrument's id already equals its Watchlist ticker verbatim, but a
curated one (EURUSD=X) doesn't."""

Looked up by the Cockpit Watchlist ticker the cache is keyed on, resolved via
instrument_service.resolve_watchlist_ticker — handles both the yfinance-suffix case
(EURUSD=X -> EURUSD) and the alias case where the catalog id and the Watchlist ticker
share no common substring at all (GC=F -> GOLD, ^GSPC -> SP500)."""
