Empty results for some tickers

I have noticed some tickers don’t seem to be returning data in the historical stock data client. Specifically I saw this today with the Asset “MITEY”, when requesting this through Alpaca python it returns an empty dataframe:

alpaca_df = self._client.get_stock_bars(
StockBarsRequest(
symbol_or_symbols=[“MITEY”],
timeframe=timeframe,
start=start,
)
).df

Am I calling this specific asset in an incorrect way?

@gbqtV The symbol MITEY represents Mitsubishi Estate Co Ltd American Depositary Shares. The reason it has no bar data is it trades Over The Counter (OTC). The Alpaca market data has only data on exchange traded securities and not those traded OTC. One can check if a symbol trades OTC by checking the assets endpoint as shown below.

Thanks for the info, I’ll filter on OTC exchanges to make sure I don’t include them
