I am trying to retrieve data from Yahoo! using the MarketData package. After adding the package and using it, I try the following and get errors:

![Error MarketData](https://global.discourse-cdn.com/julialang/original/3X/b/4/b424bb0a46acd0cb220aa53e17243f9697ff8354.jpeg)

What am I doing wrong?

Both of these work fine for me, are you on the latest released version?

I just added the package, and reading the details I now see:

![YahooError](https://global.discourse-cdn.com/julialang/original/3X/b/1/b11c642c5e6d0acb683e81c12d6f74a037014800.jpeg)

This also seems to suggest you’re on Julia version 1.4 - you should probably upgrade to 1.6.1, which is the current release.

The current release of MarketData is 0.13.4, so make sure that that’s the one you’re running, if not you might have to go back to documentation for whatever version you’re on (although it might be that the older version just flat out doesn’t work anymore as Yahoo has changed their API, as that warning suggests).
