Some tickers inaccessible #11

Closed lmlask closed 2 years ago

Some valid tickers lead to panic when fetching from Yahoo Finance, even though they are valid. Observed that on exchanges outside the US. Examples are PETR4.SA and GGBR4.SA.

Maybe Alpha Vantage would be able to deal with those better? I know Yahoo has a history of making things difficult for this kind of use.

Sometimes other tickers (such as ETH-USD) also break, but that appears to be random or based on time of request.

Yes I also noticed that Yahoo Finance was not a very reliable source. I am thinking of removing the *-fetch mode from cli-candlestick-chart. In my opinion the real role of this library is mainly to provide an API to draw charts in the terminal, not to be a bridge to brokers/data-sources.

Someone could build a tool on cli-candlestick-chart that would allow to fetch charts coming from several brokers/exchanges, that could be great, but indeed I don't think that is the role of cli-candlestick-chart
