Without being able to see all the data, we just do not know.

We are not seeing any issue with the Standard Deviation calculation until you get towards the bottom of the data. In this case, the data in the K column jumps to large values since there is no further data in the B column, so you end up with the value of the E Column.

If this is not what you are seeing, then what is the row at which the data starts to change?

I'm seeing that, is that normal? and would that affect the signals I'm trying to produce?

If what you are seeing is due to the lack of data in the source column, then this is normal. You are asking the system to take a Standard Deviation that does not include all the data.

This will only affect your signals if you are looking that far back in time. If you need to go that far back, then you need to have more Rows in your spreadsheet to make sure you have enough data going back as far as you need.
