Try this in the indicator panel replacing the last plot line in your code
def2 = Highest(zxy); // already exisiting
FirstBar = Barcount - 15;//gives last 15 bars..................NEW
Plot ( iif( barindex()>=FirstBar, def2, null)
,"def1",4,1);..................Modified

Subject: [amibroker] Use set previous period
I've made a graph
Plot (Close,"Close",1,64);
xyz = L + (ATR(14) * 2);
zxy = H - (ATR(14) * 2);
Plot (xyz,"myhigh",3,1);
Plot (zxy,"mylow",4,1);
def1 = Lowest(xyz);
Plot (def1,"def1",3,1);
def2 = Highest(zxy);
Plot (def2,"def1",4,1);
How can I get this graph to cover only a certain period of time. ie, I only
want it to start about 3 weeks ago.
I'm new to AB and not familiar with the commands and can't find it searching
the help file for probable words.
