Can you tell me why the EA does not open a position when testing, I'm not sure why - I think I wrote the code correctly.


When opening a market order (OP_SELL or OP_BUY), only the latest Bid (for sell) or Ask (for buy) prices may be used as the opening price.

something like this.

Can you tell me why the EA does not open a position when testing, I do not understand why - the code seems to be written correctly.


How can one value be higher and lower than another at the same time?

if ( price[0]<WMA0 && price[0]>WMA0 )

Also, call the indicator with a period of averaging 1 and five times, this time)

and two) the MODE_PLUSDI line where it is from in this indicator

Indicator line identifiers used when calling iBands(), iEnvelopes(), iEnvelopesOnArray(), iFractals() and iGator():

Constant Value Description
MODE_UPPER 1 Upper line
MODE_LOWER 2 Bottom line
 

Hello, everyone. A simple question.

I have a task: in indicator parameters we need to introduce a variable in which we could set a condition for if statement

For example, there is a variable:

(type?) Peremennaya="(x>y)" ;

if (Peremennaya)

{

.......

}

How to implement? Very much needed to change conditions to the prescribed algorithm.

Thank you in advance.

 
There are functions for this

How about this :

bool Peremennaya=false;
 
  if(x>y)Peremennaya=true;  
   if(Peremennaya==true)
     {
     .........
     }
  
bool Compare(double x,double y){
   if(x>y){return(true);}
   return(false);
}

void start(){
   if(Compare(x,y)){
      ... bla bla bla
   }else{
      ... bla bla bla
   }
   ... bla bla bla 
  
}
 

Gentlemen, you are offering me a hard condition and a sample.

My task is to change the area miscalculation forum in the parameter when running the indicator. I.e.

There is a certain area on the chart with different characteristics, for example (a,b,c,d,e....)

Depending on the condition of checking of the price behavior in the area, a Fiba from the area is drawn.

The checking conditions are the formula, i.e. the variable that can be changed as you want.

For example:

if ((a>b)<(c/d+4).........+10*a) is a rigid and unchangeable condition binding.

{

ObjectCreate(Fiba....)

}

I need the "external variable" to be modifiable by the user via the indicator parameter dialog,

thereby allowing to modify the test conditions.

if(external variable)

{

ObjectCreate(Fiba....)

}

 

Either you don't know how to ask the right questions, or if I understand you correctly, you have to write a detailed text string parser with a keyword detector and a full description of what follows. You either don't know or confuse the concepts.

1) a variable is not an expression, but its value.

2) An external variable is a constant and cannot be initialized by an expression.

 
FAQ:

..............

2) The external variable is a constant and cannot be initialized by an expression.

I.e. it turns out that externally I cannot change the contents of the condition, when checking it, an expression is executed.

Isn't there any way to do it?
