changing properties of standard indicators using the function "ChartIndicatorAdd"

[Daniel Weckhuyzen]

Hi, 

I can't find in the "help" of MT5 how I can change some properties of an added indicator using the "ChartIndicatorAdd" function.

For instance: I've added a standard exponential moving average using the code:

indicator_handle = iMA(Symbol(),Period(), 20, 0, MODE_EMA, PRICE_CLOSE);

 window=0;

 if (ChartIndicatorAdd(0,window,indicator_handle))

 {

 Print (__FUNCTION__, " Adding EMA's succesfull");

 }   

Now I would like to change the color of the EMA-curve and the thinkness of the line.

Is there a way to do this ?

thx for your help !!

Danny

With the help of ChartSaveTemplate/ChartApplyTemplate it is possible to do this. The example for understanding.

Thx for your help everybody !!

Until now, I think the only way out is creating the indicator myself with adding extra parameters for the colors, type and thickness.

Keep on posting !

Thx

Hi Alain an dear all,

I am currently working on exchanging und mixing data from several indicators ( https://www.mql5.com/de/articles/19 does not function, since I have a 64-bit machine and Alex provides only a exchng.dll for 32 bit).

My solution so far is, to outsource all the indicator calculation in a header(class).

                const double &Low[],const double &Close[],const long &TickVolume[],const long &Volume[],const int &Spread[])
  {

  const int ret_val_ART =  CalcART.Berechne_ATR(rates_total,prev_calculated,Time,Open,High,
                                                Low,Close,TickVolume,Volume,Spread,InpPeriod1,D_Buffer1,C_Buffer1);
                              
  
  return ret_val_ART;
  }

It would be very supportive for making the code more general and  flexible, if the property declaration:

//--- indicator settings
#property indicator_separate_window
#property indicator_buffers 2
#property indicator_plots   1

could be made within a function.

On the page https://www.mql5.com/en/docs/customind/propertiesandfunctions, we can see,  that these property setting are the only ones, which can nor be set by a function.

For sure it would be nice.

But we have to deal with that as it is I am afraid.
