On TradingView, there are some tickers with no volume data. Forex pairs and CFDs from FOREX.COM (FOREXCOM:) lack this information. ICE (FX\_IDC:) doesn't send volume for daily-based timeframes, while it is available on intraday charts. We don't calculate the volume for our own CFDs, which are branded as TVC (TVC:) tickers.
Some crypto pairs and most indices also show N/A when the volume indicators are applied. TradingView will display volume when it is received from the data provider. TradingView is planning to add volume data for indices in the future, but there's no ETA at this time.
