Error messages claim "possibly delisted" even when Yahoo explains the real cause #2902
Description
Describe bug
Every YFPricesMissingError message starts with $TICKER: possibly delisted; ..., even when Yahoo's response contains an explicit reason that has nothing to do with delisting. Example, a 30m request older than Yahoo's 60 day intraday window:
$SPY: possibly delisted; no price data found (30m 2026-03-16 -> 2026-03-23) (Yahoo error = "15m data not available for startTime=1773633600 and endTime=1774238400. The requested range must be within the last 60 days.") (30m resampled from 15m)
SPY is not delisted. The request was outside the allowed range, and Yahoo said so in the quoted error. The speculation sends users down the wrong path (see #1713, #1797, #2044, #2052 for examples of the confusion). When a ticker really is dead, Yahoo's own description already says "No data found, symbol may be delisted", so the prefix adds nothing there either.
Suggested fix
When history() has an explicit error description from Yahoo, suppress the "possibly delisted" prefix and let Yahoo's stated reason stand. Keep the prefix where Yahoo returns nothing and delisting is a plausible explanation. Happy to submit a PR, as a follow-up to #2900 which fixed the interval part of this same message.
Simple code that reproduces your problem
import yfinance as yf
import datetime as dt
start = dt.date.today() - dt.timedelta(days=120)
yf.Ticker("SPY").history(start=start, end=start + dt.timedelta(days=7), interval="30m", raise_errors=True)Debug log with debug logging enabled
