Indicators cannot work together

Daniele Nerstini 2023.03.27 15:23

Hi everybody and a good day. I coded 6 indicators that trace automatic channels on different timeframes, they work flawlessly alone but they stop working when applied together to the chart.

Every indicator use a handle to get the timeframe IMA data and I declared them in OnInit as you said.

First indicator handle:

void OnInit()
  {
  handleM1=iMA(NULL,PERIOD_M1,1,0,MODE_SMA,PRICE_MEDIAN);
  }

second indicator handle:

void OnInit()
  {

  handleM5=iMA(NULL,PERIOD_M5,1,0,MODE_SMA,PRICE_MEDIAN);

  }

Third indicator handle:

void OnInit()
  {

  handleM15=iMA(NULL,PERIOD_M15,1,0,MODE_SMA,PRICE_MEDIAN);

  }

Fourth indicator handle:

void OnInit()
  {

  handleH1=iMA(NULL,PERIOD_M1,60,0,MODE_SMA,PRICE_MEDIAN);

  }

Fifth indicator handle:

void OnInit()
  {

  handleH4=iMA(NULL,PERIOD_M1,240,0,MODE_SMA,PRICE_MEDIAN);

  }

Sixth indicator handle:

void OnInit()
  {

  handleD1=iMA(NULL,PERIOD_M1,1440,0,MODE_SMA,PRICE_MEDIAN);

  }

Also, every indicator use different variable names for the icons, the lines and internal calculations.

During debug I noticed the indicators stop calculate the iMAs when working together. What could it be the problem?

Are you using objects on chart? Sometimes object names interfere with each other.

Daniele Nerstini 2023.03.27 15:46 #2

Yes, there are many objects, buy I accurately named them differently. But even if the object name interfered with each other I cannot explain why the iMA calculations stop.

Is there some kind of buffer or other internal metatrader function that get overwhelmed?

Difficult to say without source file.

Daniele Nerstini 2023.03.28 12:40 #4

I don't think the code would clarify anything, there are only internal calculations and it would lead out of topic.

I'm only wondering if in the metatrader there is some kind of buffer or other internal function that get overwhelmed by using too much the iMA function or other function. Thanks

What does this "stop calculate" mean?

Variable names are irrelevant. Only Global Variables of the Terminal and object names can be seen outside a program.

It is almost always your code.
On MT4: Unless the current chart is that specific symbol(s)/TF(s) referenced, you must handle 4066/4073 errors before accessing candle/indicator values.

Wait, do you call them together or do you create the OnInit function for each one?

void OnInit()
  {
  handleM1=iMA(NULL,PERIOD_M1,1,0,MODE_SMA,PRICE_MEDIAN);

  handleM5=iMA(NULL,PERIOD_M5,1,0,MODE_SMA,PRICE_MEDIAN);

  handleM15=iMA(NULL,PERIOD_M15,1,0,MODE_SMA,PRICE_MEDIAN);

  handleH1=iMA(NULL,PERIOD_M1,60,0,MODE_SMA,PRICE_MEDIAN);

  handleH4=iMA(NULL,PERIOD_M1,240,0,MODE_SMA,PRICE_MEDIAN);

  handleD1=iMA(NULL,PERIOD_M1,1440,0,MODE_SMA,PRICE_MEDIAN);
  }

No. The issue comes from your code.

Hi, Carl. It means the lines on the screen stop moving because the iMA is not calculated anymore inside the code. I'm sure of that because I used a Print line to watch the iMA progress.

Hi Manuel. Every indicator has its own OnInit handles call as I explained above.
