> {code}
> The reason is that Yahoo Inc. (YHOO) is now trading under the name Altaba
> Inc. (AABA) and therefore the stock ticker does not return any valid
> information anymore. The response from the Yahoo Finance API looks like this:
> {code}
> "IBM",153.32,2953715,"1:07pm"
> "GOOG",963.36,595534,"1:07pm"
> "AAPL",149.6144,10235115,"1:07pm"
> "YHOO",N/A,0,N/A
> {code}
> The application crashes because the StockTickInput operator can't parse "N/A"
> as a valid double. Changing all the ticker symbols from YHOO to AABA should
> fix this.
