These filters compare the current price to the price 5, 10 or 20 days ago.  These are trading days, not calendar days.  So these filters look at changes in the last week, two weeks, and month.

The formula for the $ versions is simply the current price minus the old price.  Bigger numbers mean that the price has moved up more.  Negative numbers mean that the price has moved down.  0 means no change.

You can also filter these in %.  These use the standard percent formula:  (new value – old value) / old value * 100.

The current price is based on the last print.  There is no smoothing or averaging.  This updates before, during, and after market hours.

The old price is always based on the close.  If you are look at the Up in 5 Days filter, then you are comparing the current price to the close 6 days ago.  If you are looking at this filter at the open, then you will see the price change for exactly 5 days.  If you are looking at this filter one hour after the open, then you will see the change for 5 days and one hour.  At lunch time you will see the change for 5½ days.  At the close you will see the change for 6 days.
