When you follow a token by a number, or by a period and then a number, that number is considered a "qualifier" and references the tokens value that many bars back.
You can also use CL instead of CLOSE.
CL
is the close of each bar.
CL.1
is the previous close of each bar.
CL.2
is the close of 2 bars previously on each bar. Effectively shifting the close values right by 2 bars. Same with VPS.1, it's just grabbing the VPS value from the previous bar.
