hi guys is it possible obtain something like this?
Code
vars Price = series(priceClose());
var per = 50;
  int i = optimize(0,0,2,1);
vars a[3] = {
                    series(SMA(Price,per)),
                    series(EMA(Price,per)),
                   series(TEMA(Price,per))
                    };
vars Trends1 = a[i];
if(crossOver(Price,Trends1))
enterLong;
if(crossUnder(Price,Trends1))
exitLong;


obviously it goes on error frown
thanks

Now if you read the manual and look at the definitions of the functions SMA, EMA, and TEMA, you will learn the second argument needs to be an int rather than a var. (A var is actually a double.)

Now here’s the other issue:

You are optimizing to select one of three series calls in an array, but you chose to call all three series in all cases? Even if it did compile, very suboptimal.

So do this:
Declare a vars, no definition, no array.
Then based on the optimize output, use an if-then statement to determine which series call goes to the vars.

thank you andrew i get it in this way if it can help other forum's users
Code
	
vars Price = series(priceClose());
int per = 50;
int x = 3;
 int i = optimize(0,0,2,1);
 vars Trends1;
vars Trends2;
   if(i == 0) {
		Trends1 = series(SMA(Price,per));
		Trends2 = series(SMA(Price,per*x));
		}  
	else if(i ==	1) {
		Trends1 = series(EMA(Price,per));
		Trends2 = series(EMA(Price,per*x));
		}       
	else if(i ==	2) { 
	Trends1 = series(TEMA(Price,per));
	Trends2 = series(TEMA(Price,per*x));
	}    


but i still dont understand what im doing wrong in the previous array. I still get the syntax error and i tried various combination of ";","}", "," or blank spaces but nothing, still get the same error

This is probably a limitation of Lite-C. I don't think you can initialize an array with functions upon declaration.

That's right. Arrays are initialized with constants, not with functions.
