Blacked out graph

Can someone tell me why on certain stocks , when you go through the time frames:
1day,1month etc sometimes the graph is black in colour??

Have you got an example?

The data will only be since adding the new stock but I’ve never seen a black graph.

I assume you’re on about app rather than desktop?

This is today, and when i click on a week its green again ??

Ah yeah it’s black showing no change.

It’s doing Saturday Vs Friday so as the markets are shut it would be the same (0% change)

Weirdly some aren’t black so not sure why it’s inconsistent.

Ok, thanks, yes some all others are green .,.,
