My goal is to have a chart that shows only the last hour based on 1 second bar, when setting the data range for 60 minutes Bars Back it works as it should:

However when setting the data range for 3600 Bars Back for 1 second resolution the result is much more than one hour of data as there wasn't a trade at every second:

so my question is how set a chart based on 1 second resolution to hold only one hour of data?
Thank you all in advance,
