The link to share my chart is literally 4096 bytes. WTF yahoo!
To share a chart, the link needs to be short enough to be usable.
My chart with 9 tickers showing year-to-date provides a share link of 4096 bytes. That link is not shareable. I'm not even sure it is complete because 4096 seems very suspicious that it may have been truncated.
If you cannot create a useful link, then you should use a link shortening service (assuming they are even capable of storing such a ridiculous link).
