Hi guys, I am trying to get a stable integration with historical data for symbols and I thought Yahoo Finance is the best data source ( please let me know in case you know a better one - I had Alpha Vantage and they provide no support. Also on daily bases at least a security has wrong data). - This is more likely informational stuff. Yahoo Finance also provides wrong data - please check out CRC - which is no longer available on site just with a deep search. Please let me know if there is a way to acknowledge data received is wrong or should not be available, in case you know there is such a way other than simply integrating multiple data sources and implement a validation and promotion point. Many thanks in advance!

If you need to know you are getting correct data you should be considering a commercial data provider.
