convert indicator array code for EA code

i tried several method but fails

i dont want to use icustom, i want directly use indi code to EA

indicator here:

Inserted Code

         double atr   = iATR(NULL,0,VolPeriod,i+1);
            if (atr!=0)
                  vol[i] = range/atr;
            else  vol[i] = 0;                  
      }
      for(i = limit; i >= 0; i--) volavg[i] = iMAOnArray(vol,0,Smooth,0,SmoothMethod,i);

         if (DeviationsForSteps>0)
         {
            double deviation = DeviationsForSteps*iStdDevOnArray(vol,0,VolPeriod,0,MODE_SMA,i);
               if (vol[i] > volsteps[i+1]+deviation) volsteps[i] = vol[i];
               if (vol[i] < volsteps[i+1]-deviation) volsteps[i] = vol[i];
          }
          else volsteps[i] = 1;              
      }
      
   return(0);
}

i want this indicator code to apply in EA code inside
i set variable to collect array data but failed
Inserted Code
 x = vol[0];
 xx = volavg[0];
xxx = volsteps[0];

Without icustom is it possible?

Converted into a function that you are going to insert into your expert code.You define the 3 arrays at global variables as i did .The function will resize and initialize them based on the number of bars you want to calculate.The barsNumber need to be bigger than your VolPeriod which is 14 in this case.If you need to access only the last value of the 3 arrays you can calculate max 50 bars for example.

at global variables inside EA,only 1 element arrays since the function will resize them
Inserted Code
double vol[1];
double volavg[1];
double volsteps[1];

the function to insert into EA code
Inserted Code
void VolAvg(int barsNumber,int VolPeriod,int  VolPrice,int Smooth ,int SmoothMethod,double DeviationsForSteps)
{
      ArrayResize(vol,barsNumber,0);
      ArrayResize(volavg,barsNumber,0);
      ArrayResize(volsteps,barsNumber,0);
      ArrayInitialize(vol,0);
      ArrayInitialize(volavg,0);
      ArrayInitialize(volsteps,0);
      
      Smooth = MathMax(Smooth,1);
      for(int i = barsNumber; i >= 0; i--)
      {
         double range = MathMax(High[i],Close[i+1])-MathMin(Low[i],Close[i+1]);
         double atr   = iATR(NULL,0,VolPeriod,i+1);
            if (atr!=0)
                  vol[i] = range/atr;
            else  vol[i] = 0;                  
      }
      for(i = barsNumber; i >= 0; i--) volavg[i] = iMAOnArray(vol,0,Smooth,0,SmoothMethod,i);
      for(i = barsNumber; i >= 0; i--)
      {
         volsteps[i] = volsteps[i+1];
         if (DeviationsForSteps>0)
         {
            double deviation = DeviationsForSteps*iStdDevOnArray(vol,0,VolPeriod,0,MODE_SMA,i);
               if (vol[i] > volsteps[i+1]+deviation) volsteps[i] = vol[i];
               if (vol[i] < volsteps[i+1]-deviation) volsteps[i] = vol[i];
          }
          else volsteps[i] = 1;              
      }
}

on the onTick() expert loop you first call the function to load the 3 arrays and only after your expert will use the 3 arrays to trigger events
Inserted Code
//load the arrays
VolAvg(100,14,PRICE_CLOSE,3, MODE_LWMA,2.0);
//use them
if(vol[0]>  ... etc... do whatever you want...trigger buy/sell
if (volavg[0]>  ... etc... do whatever you want...trigger buy/sell
if( volsteps[0]> ... etc... do whatever you want...trigger buy/sell

Here you have your indicator converted into a function still working great,calculating only last 100 bars

The function inside the EA gives instant Array out of range error ,because is calculating from the last bar to the first bar..I modify this
Inserted Code
ArrayResize(vol,barsNumber+2,0);
ArrayResize(volavg,barsNumber+2,0);
ArrayResize(volsteps,barsNumber+2,0);
and clear the error but than i notice diff values vs the same function inside the indicator.
You need to go back to the iCustom method.When the indicator is inside the ea it gives alot of bugs,errors.Only the vol array is stable.I compared with the values given from the indicator.
The same function inside an indicator runs perfectly but inside an EA even if i increased Array size more than needed act strange.I'm sorry for you but i found similar problems when i put on the same chart an EA and a script.The EA was making the script to act in a really strange way.With only the script on the chart the script was perfect,...only the EA on chart , the ea was perfect...when both EA and script were on the same chart ,the EA was crazy ,the script was crazy....just because MT4 doesn't compile the code but is unifying diff codes into one at runtime and combine different variables which also may have the same names )...MQL4 is full of problems,i don't use it ,i code in C++ only.

for example when the indicator and the ea are dropped on GBPUSD both vol and volsteps arrays are perfect and the volavg is with error and without making any modification when dropping on USDCHF only the vol is good , both volavg and volsteps are giving problems ...this means bugs on MT4 since the code is unchanged ,only the symbol was changed.When i made the tests i fully reinitialised the expert and the indicator to clean the memory.
check the diffrences,green= identical.

MT4 translates the MQL4 functions into lower level code at runtime but is not doing it in the right way.I hope somebody can give you a better solution.As indicator the function is OK ...as EA is not ok anymore.Even initialising the arrays on the expert Init ,not inside the function or giving them more elements than the function is using on the global definitions ex. vol[500] and the function only need 100 elements doesn't solve the problem.

OMG... don't actually do this, munna! This is such a antiquated and amatuer way to code. You're going to clutter up your global namespace with a bunch of unnecessary global arrays as artifacts from an indicator source that shouldn't have been included in the first place. This is really-really bad advice!

Let's start with why you want to include the indicator in the expert code...

 

  1. Is it because you think it is an optimization?

    1. If so, its not. It's faster to allow your indicator to run asynchronously with your EA



  2. Are you trying to hide the implementation details of your EA so you only have to distribute one file?

    1. If that's the case then you need to still use iCustom as you normally would but include your indicator as a resource. When you compile your EA the indicator will be packaged in with (hidden inside of) the .ex4 file.

i appreciate the respond...
Nicholisen was right,including as resource is better.
Working with custom indicators included as resources
One or several custom indicators may be necessary for the operation of MQL4 applications. All of them can be included into the code of an executable MQL5 program. Inclusion of indicators as resources simplifies the distribution of applications.
Below is an example of including and using SampleIndicator.ex4 custom indicator located in terminal_data_folder\MQL4\Indicators\ directory:
//+------------------------------------------------------------------+
//| SampleEA.mq4 |
//| Copyright 2013, MetaQuotes Software Corp. |
//| https://www.mql5.com |
//+------------------------------------------------------------------+
#resource "\\Indicators\\SampleIndicator.ex4"
#property strict
//+------------------------------------------------------------------+
//| Expert initialization function |
//+------------------------------------------------------------------+
int OnInit()
{
//--- get custom indicator value
double value=iCustom(_Symbol,_Period,"::Indicators\\SampleIndicator.ex4",0,0);
PrintFormat("Indicator: iCustom value=%f",value);
//--- ...
return(INIT_SUCCEEDED);
}

I Agree with nicholsen.

there is no other way unless you infiltrate to existing namespace.
MQ4 and ex4 are different.
Its okay to have 2 source code. as long as you have one compiled app, there will be nobody to know.

Interesting...I had no idea we could include an indicator as a #resource. When I run my EA in Display/Debug mode, I do call several icustom "indicators" (more like tools). Question: like my EA, I compile my tools also frequently. If I use a resource as EXE (in the example from masterx, would the EA automatically reflect the changes or do I have to recompile the EA also?

Thanks for the example Master. Great things are possible when we are open to collaboration and disagreements :-)

There's a small performance penalty when you compile your indicator with the EA. Don't do it unless you intend to distribute a single executable

in main indicator when i use #property strict no buffer showing in data window also in chart

Inserted Code
#property strict
//------------------------------------------------------------------
#property indicator_separate_window
#property indicator_buffers 3
//#property indicator_color1  DarkGray
//#property indicator_color2  PaleVioletRed
//#property indicator_width2  2
//#property indicator_level2  3
//#property indicator_minimum 0
//#property indicator_levelcolor DarkGray

but we are using #property strict in our coded EA, is the cause that indi code not working in EA?
please assist me with converting this TMA indicator to an Ea

hello there !
how to code EA to take 1 trade per signal and wait for new signal for next trade even it hit tp.

Example
if EA place buy trade in buy signal and it hit the 5pip and current trend is buy when tp hit it will not place anymore trade in buy trend it will wait for next new signal which will be sell then it will place sell trade .


any code or function for this
