Is there an instruction that invokes the indicator that is being built of the precedent bar?
similar to the instruction "PREV" of MetaStock:
"Self Referencing Formulas Using PREV
The PREV constant allows you to create self-referencing formulas. A self referencing formula is one that is able to reference the "previous" period's value of itself.
For example, the following is an example of a self referencing formula:
((H+L+C)/3) + PREV
This simple formula divides the high, low, and closing prices by 3 and then adds this value to yesterday's value of the ((H+L+C)/3)."
thank you very much
