The daily line means that the shortest time interval you can see on this map is one day, that is, 24 hours. Generally, when you look at the daily line, the coordinates below it are marked every 20 days, but if you click the mouse or look at it with the crosshair, you can see the daily transaction price, but you can't see the transaction price of 1 hour or a few minutes. So is the weekly line.

I hope my answer can help you.

Is there a problem?
