Question.
I am looking to switch to Sierra.
I do have a question, if you load a footprint chart will it show historical data?

will the executed bids and asks of the footprint show historical data as in the prior data when your cpu wasn't on?

This may seem a simple question, maybe I have a misunderstanding of how data is used.

Yes, SC records bid/ask so you can reconstruct delta/footprint without having it to be on and recording like NT does with Gomi.

Yes, just load the "numbers bar" study and you'll see the historical data.
