Some stock Tickers(NSE & BSE) are missing in Timeseries AlphaVantage module about openbbterminal

Hey @Pranav4399,

Thank you for feedback.

Yes, you're right. I just checked and AlphaVantage doesn't seem to be the best for share prices outside NYSE/NASDAQ, as I saw some people asking for such "list".

I'll try to implement a fallback mechanism to get historical data from other sources in case they aren't available from AV. It may be worth looking into Yahoo Finance, or IEX.

We should add alternative APIs for market data acquisition

I've implemented this with Yahoo Finance in #128 (the data is acquired from quandl)

Can you let me know if the tickers you usually use are available?

I tested some of them, some work some don't. The ones that do, still aren't available on Alpha Vantage. So regardless it's an improvement. The others that I've tried and don't work, I get the message from yahoo finance API:

load 20MICRONS

1 Failed download:
- 20MICRONS: No data found, symbol may be delisted

I'll close this issue for now. If Yahoo Finance is still not good enough, feel free to open a new issue!
