Requesting advice on how to describe financial data (stock charts) as tabular data.

Okay. Maybe one more bump then.

I would appreciate advice on:

1. Ways to describe this data in my tables. Maybe my initial proposal is as good as it gets? Or might there be smarter ways that makes it 'easier' to read and sort the data?

I don't have any immediate ideas myself as this was the best I came up with on my own.


2. Ways to visualize the data on charts.

I liked the suggestion by come2me, but was unable to create it myself...

Every day starts at 09:30 and ends at 16:00. I suppose I would have to add both these time values to my tables in order to get consistent charts of the same length/magnitude?

Another idea I like is to simply plot the up moves as vertical bars above a zero line and down moves below. Something like what I'm attaching.

Thanks a lot in advance!
