Btw symboldata.numrec is just an internal variable that holds the total number of bars that are historically loaded for the symbol in question.
The internal variable "bar" holds the bar number of the current bar being processed. The internal loop goes from past to present. The first bar number is zero - the most recent bar number is symboldata.numrec-1.
That's about it.
