It'll take until retirement to disassemble it... :-)))

Hi all!

I have a problem when using a sliding AMA, I got it from here https://www.mql5.com/ru/code/7378

I put the simplest code 

double ama=iCustom(NULL,0,"AMA",0,0,0);
double ma=iMA(NULL,0,21,0,MODE_EMA,PRICE_CLOSE,0);

if (ama > ma){Opn_B=true;}
if (ama < ma){Cls_B=true;}

It does not work like in EA's terms and conditions. After the test, the AMA indicator itself appears with a period of zero.

But the period of the indicator itself is 9. I do not see any errors in the journal.

What am I doing wrong?

Between 3 (indicator name) and the last two parameters you specify the indicator parameters you want, you pass in the fourth parameter 0, which is what you get. If the default is 

double ama=iCustom(NULL,0,"AMA",0,0);

Thank you! It worked!

How to transfer a period for optimisation through the EA to the indicator?

Hello! Having EAs on a previous version of MetaTrader I upgraded the terminal. After that I went back to 509. So the EAs have "been" in 60... Bild, they returned to the terminal version they were written on.

The question is: What to do with those EAs that stop opening deals in the Strategy Tester after "coming back" and those that cannot be tested anymore (the start button in the Strategy Tester simply does not respond to a click)?


Since no one answers, I will rephrase the question - what should be done in the Expert Advisor, written for 509 build, so that it works correctly on the new platform?

In iCustom() there are parameters that you pass to the indicator from 4 onwards according to their quantity in the indicator, the last two parameters are reserved for the indicator buffer number and shift relative to 0 (last) bar

extern int opt = 9;
void OnTick()
{
double ama=iCustom(NULL,0,"AMA",opt,0,0);
}

Like this for 4 parameters!

extern int periodAMA=9; 
extern int nfast=2; 
extern int nslow=30; 
extern int G=2; 

double ama0=iCustom(NULL,0,"AMA",periodAMA,nfast,nslow,G, 0,0); // на нулевом баре
double ama1=iCustom(NULL,0,"AMA",periodAMA,nfast,nslow,G, 0,1); // на первом баре
 

I am eating to write the Binet formula in µl, tell me what is wrong with me,

int FiboN = MathRound((1/MathSqrt(5))*(MathPow(((1+MathSqrt(5))/2),N)-MathPow(((1-MathSqrt(5))/2),N)));
Thank you

Not to compile it in builds older than 509... Just put the file compiled in 509 build into the appropriate folder in the new build.

Thanks, I checked it with the script it works!

And in general, when using two AMA, is it possible to pass two different periods from the Expert Advisor during optimization?

Yes.
