[amibroker] Range of Equity() different than AA?

[Lou H <lhoward121@xxxxxxxxxxxxx>]

When scanning for signals for the next day, I set the n=1 in 
AA.  However, from what I can tell of the documentation, the Equity() 
function gets its range parameters from AA, ie, n=1 ,  Sometimes I would 
like the "range" values for Equity() to be different than AA, for example in the 
little routine below (courtesy of TJ) I would like to set the number of bars to 
be worked on as say n=60.  Is there any way of doing this?  (Note - 
that the range I'm interested in is the number of bars to be considered as used 
in the Equity() documentation not to be confused with the use of "range" 
in the routine below referring to a parameter of the Cross() 
function.
