[amibroker] Nested if-statements

["carlacash26" <carlacash26@xxxxxxxxx>]

Hi!

I have a system that has a few indicators. I want to code this in 
amibroker.

I want a buy signal when all of the indicators acts in a specific way.

When one of my indicators acts the way i like a variabel is set 
to "true" (or 1), when all of these are true, i want the buy signal. 

So when a,b,c, or d are == 1 then give buy signal.
Is this done like this with nested if-statements?

if (a == 1){
 if (b == 1){ 
  if (c == 1){
   if (d == 1){

     BUY-SIGNAL

          }
            }
              }
                }       

Thanks!
