Was trying to pull intraday data with free api from alpha vantage but unable to download it; While At the same time I'm able to download daily OHLC data. Also, intraday data query is working for NYSE stocks but not working for NSE or BSE stocks.
I tried lot but not worked for me; also, some time back the same query thrown the result/s and now it is not throwing.
I am using R for testing.
If you have any other free data source for live data(NSE feeds) request you to share it.
