hi, i have this code(from amibroker AFL library)
i have taken out the daily pivots,
but what im trying to do is adjust the code so that the weekly and monthly 
pivot points adjust(each week),,  at the moment i only have one pivot line 
which. so id like to see what the pivots were in the past and then know when 
they change for the new week.
does anyone know how to adjust the setting to add a 3week pivot point in there, 
 so i have weekly, 3week and monthly pivot??   
any help would be fantastic and very much appreciated. learning to code is 
taking a long time..

cheers
here is the code i have

/*SUPER PIVOT POINTS ver 1.3 day week month
by Avi b a
/***************************************/
/*
SUPER PIVOT POINTS can by used in 2 ways:
if you choose daily, the pivots are calculated from the previous day,
this can be used for daily charts.
the second option is next day for EOD charts.
for all the options available right click on the chart parameters.
to utilize all the program features you need amibroker from version 4.80.1 and 
above.
enjoy!
