Indicator one buffer for one line with 2 color

[Rinaldoa70]

Hi , I need some clarification if possible: I seem to have understood, reading almost all the posts on the subject, that being able to make a condition work where the color change of the line generates a buy or sell signal depends on the number of indicator buffer. so if there is only one buffer you can't get the signal.
I noticed a couple of answers talking about the block indicator visible but I don't understand if even then it depends on the number of buffers or if there is a way to generate the signal. Thanks a lot for being available to anyone who replies.

Is it an MT5 indicator? If so more than probably there will be one only buffer with all colours you need. Sadly, fxDreema cannot understand that. It need one separate buffer per colour.

Yes it is an MT5 indicator, HMA … it is how i understood… thanks very much for replay!

You're welcome.

@Rinaldoa70 In single buffer outputs, color changes are made by comparing x number of previous candles. Cadle Close1>Candle Close2 gets a rising color.

If we examine the code, for example:

  {
     if(ShowInColor && moving[shift-1] != EMPTY_VALUE)
     {
     trend[shift] = trend[shift-1];
     if(moving[shift] > moving[shift-1]) trend[shift] = 1;
     if(moving[shift] < moving[shift-1]) trend[shift] = 2;   
     }    
     else trend[shift] = 0; 
  }

if (moving[shift] > moving[shift-1]) trend[shift] = 1;: If the moving value on the current bar is greater than the moving value on the previous bar, it assigns a value of 1 to the current shift index of the trend sequence. This represents an uptrend.

if (moving[shift] < moving[shift-1]) trend[shift] = 2;: If the moving value on the current bar is less than the moving value on the previous bar, it assigns a value of 2 to the current shift index of the trend sequence. This represents a downtrend.

Set the "Trace" box for the buffer you want to check. You can develop a condition based on the output data.
