No prices found for security #{symbol} on date #{date}

Error message

No prices found for security #{symbol} on date #{date}

What it means

Provider::TwelveData::InvalidSecurityPriceError raised in fetch_security_price when the underlying fetch_security_prices call for a single-day range (start_date == end_date) succeeded but produced zero usable Price rows. Either values came back empty for that date or every close was nil/<= 0 and got filtered out.

Solutions

1. Check whether the date is a trading day for that exchange (weekends/holidays have no daily bar)
2. Widen the window: call fetch_security_prices with start_date a few days earlier and pick the latest bar <= target date, instead of the exact-date helper
3. Verify the symbol is still valid via search_securities / fetch_security_info; rename mappings go stale
4. For listing-date issues, confirm the security existed on the requested date

Example fix

// before
price = provider.fetch_security_price(symbol: "AAPL", exchange_operating_mic: "XNAS", date: Date.new(2026, 8, 16)) # Sunday

// after
begin
  price = provider.fetch_security_price(symbol: "AAPL", exchange_operating_mic: "XNAS", date: date)
rescue Provider::TwelveData::InvalidSecurityPriceError
  prices = provider.fetch_security_prices(symbol: "AAPL", exchange_operating_mic: "XNAS", start_date: date - 5.days, end_date: date).data
  price = prices.select { |p| p.date <= date }.max_by(&:date)
end

trading_day = date
trading_day -= 1 while trading_day.wday == 0 || trading_day.wday == 6 # cheap weekend check
price = provider.fetch_security_price(symbol:, exchange_operating_mic:, date: trading_day)

begin
  provider.fetch_security_price(symbol:, exchange_operating_mic:, date:)
rescue Provider::TwelveData::InvalidSecurityPriceError
  prices = provider.fetch_security_prices(symbol:, exchange_operating_mic:, start_date: date - 7.days, end_date: date).data
  prices.select { |p| p.date <= date }.max_by(&:date)
end

When it happens

Trigger: Requesting a price for a date the market was closed (weekend/holiday), a date before the security listed, or a delisted symbol; requesting a date in a timezone such that Twelve Data has no daily bar; all closes filtered by the price<=0 guard.

Common situations: Valuing a portfolio 'as of Sunday'; backfilling historical prices before an IPO date; ticker renamed (TWTR → X) so the old symbol has no data.
