code for roi_lb and roi_ub

[SUSHANTH009]

I apologize if there is any silly mistake or there is any another code already for this
I have used this code to calculate roi_lb and roi_ub

I got roi_lb: 39.86
and roi_ub: 279225.0

is there any issue with my data or code ?
or its completely fine ?

It's totally fine, but as you can see in your code, the price range is too wide, which consumes more memory. As the name suggests, it's best to focus only on the range of interest. For example, in the case of ETHUSDT, the average price ±50% of the data period should be sufficient.
