Re: [amibroker] calculating the mean of only some of the observations in an array ?

["Ara Kaloustian" <ara1@xxxxxxxxxx>]

if you are using loops and you know when your signal was generated, use that 
bar number as the starting poing point for your loop. Pick an end point as 
you edesire.

a = SignalBarNumber;
b = Bars required in your calculation;

for (i=a; i< a+b; i++)
