real_time values are not shown

[piratmc]

Hi
currentTradingSession = StockQuote::Stock.quote(tickers[n])

I'm testing live currentTradingSession.ask_realtime and other real_time values are returned as NilClass.
Other non real_time values are properly returned as Float but seems like 20 minutes behind compared to actual prices.
Is this a known issue and a limitation of gem/API or am I doing something wrong?
Thank you!

@piratmc Looking at an aapl quote after trading hours I notice that ask_realtime is nil. Perhaps, those values are only available while the market is open? Or it may no longer be available through the yahoo api.

Unfortunately, the delay is a function of the Yahoo API. Originally the gem used the google finance api, before it was deprecated, which seemed to be 'more real-time'. In my experience, the closest I have been able to get to 'real-time' is with the TradeKing API (https://github.com/tyrauber/tradeking).

Thank you for reply.
I was checking values DURING trading session so expected Float but not Nil’s for real-time values.
If you have time to check out if these numbers still available via yahoo API’s that would be great. Perhaps it’s just na name change or small things like that causes the return to be Nil during open trading session.
Regardless, thanks work your work.
And thanks for a link.

@piratmc Unfortunately, it is not an attribute change or parsing issue. The raw data includes null for those values in the response. I have no idea why.

@piratmc I am going to close this for now, but let me know if the above is not correct or you think there is something we could be doing differently here.
