surubabs:

Sorry some spelling mistake,

i want the width of the band for this it need some calculation like

Width=(upperband-lowerband)/baseband

so is it possible to do this calculation inside the ea ?

how to define this ? when i tryed getting an error,

Width[]=(Upperband[ ]-Lowerband[ ])/Baseband[ ],

please advaice 

Show real code of what you are trying please.

I am still working on it sir, when u replay to my post, i post what i am working on it,
  • Why didn't you read documentation ? MathMax and MathMin take only 2 arguments.
  • What is    out=(inputs,weight); ?

i tryed to understand Docs in mathfunctions, but i couldint find the right one boz i dont know which one should i use.

i have been trying one by one last many hours can u show me the right method ?

Hi 

The MathMax  function returns the maximal  value of two values

 double x_max=MathMax(iBBMidle[ArrayMaximum(iBBMidle)],iBBUp[ArrayMaximum(iBBUp)]);
     

 

The MathMin  function returns the minimal  value of two values

 

 double x_min=MathMin(iBBMidle[ArrayMinimum(iBBMidle)],iBBUp[ArrayMinimum(iBBUp)]);

Yes, u r right ,

 what i want to do is iBBUp-IBBLow/iBBMiddle,

then name it was width, the values return to width, if the value increasing ex: width>0 a buy open(upside break out), width<0 a sell open(down side breakout). 

i dont know the exact code how to impliment it.

i am trying to code it with nural network method.

how impliment it please help.

What neural network has to do with your "width" ? It's hard to follow you.
