My first languaje is Spanish so im going to try to explain the idea
Make an indicator that show how quickly change the price something like:
If you have 60 seconds how many times the price change it in this 60 seconds and make an average of how many changes do the price in the last minute.
So if in the first minute we have 30 changes of price and in the second minute we have 70 changes that means that in the second minute we have more volatility than the first one.
That can be in periods of hourly and make an average of volatily to compare with the volatility of the currect period.
Yo can put 2 columns and 61 Rows something like this:
Minute Changes
1 32
2 15
3 11
4 56
5 43
6 52
7 66
8 12
9 19
10 33
11 54
12 28
13 45
etc
