Custom Indicator Not showing correct Values of the Trendline

[Arcee Palabrica]

Hi All,

So I have this simple code that Alerts the Value of DEMA.

However when you look at the chart the trendline doesn't seem to hit the correct value of DEMA.

Here's the simple code:

#property copyright "Copyright 2020, Arcee P. Palabrica"
#property link      "https://www.mql5.com"
#property version   "1.00"
#property strict

 extern int DEMAPeriod = 20;

void OnTick()
  {
  if(isNewCandle())
    {
     double valueofDEMA = iCustom(NULL, 0, "DEMA", DEMAPeriod, 0, 0);
     Alert("DEMA @ ", Time[0], " is ", valueofDEMA);
    }
     
  
  }

  
  bool isNewCandle()
  {
   static datetime saved_candle_time;
   
   if(Time[0] ==  saved_candle_time)
     {
      return false;
     }
   else
     {
      saved_candle_time = Time[0];
      return true;
     }
  
  }

But this is how it's shown in the chart. (please see attached screen shot)

At 2019.01.02 00:00:00 the trendline should be 1.27189266216272. But it sits around 30 pips lower that where it should be.

Thanks in advance.

double valueofDEMA = iCustom(NULL, 0, "DEMA", DEMAPeriod, 0, 1);
valueofDEMA = NormalizeDouble(valueofDEMA, _Digits);

try setting the value to 1 bar

double valueofDEMA = iCustom(NULL, 0, "DEMA", DEMAPeriod, 0, 0);

You are passing one parameter. We have no idea which DEMA you are using. This one, for example has price first then length.

Thanks so much. And I've also learned normalize. Thanks for that as well

This indicator looks promising. I'll make another ea using this one. Thank you
