Custom MACD Histogram Not Accurate Needing One More Decimal Place: mql4

[sarahfoxwell]

I have created a MACD histogram but it is only showing 4 decimal places such as 0.0013 and I would like 0.00130 so one more place or more. I have tried to use NormalizeDouble but no change... Does anyone know how to add a decimal place to get more accurate readings? Regards.

double currentMACDLine= iMACD(_Symbol, _Period, 12, 26, 9, PRICE_CLOSE, MODE_MAIN, 0);

  double currentMACDSignal = iMACD(_Symbol, _Period, 12, 26, 9, PRICE_CLOSE, MODE_SIGNAL, 0);

   double prevMACDLine =iMACD(_Symbol, _Period, 12, 26, 9, PRICE_CLOSE, MODE_MAIN, 1);

   double prevMACDSignal = iMACD(_Symbol, _Period, 12, 26, 9, PRICE_CLOSE, MODE_SIGNAL, 1); 

   double currentMACDHistogram= NormalizeDouble((currentMACDLine - currentMACDSignal),6); 

   double prevMACDHistogram = NormalizeDouble((prevMACDLine-prevMACDSignal),6);

Normalise has nothing to do with the situation. If you have a 5 digit broker, then data will have the 5 digits. The problem in many custom indicators' code, including yours, is that they do not set the number of digits to be displayed in the OnInit event handler.

IndicatorSetInteger( INDICATOR_DIGITS, _Digits );

How to trim to i.e. 2 decimal places in the Data window?

Please read the documentation. That is not the way to use the "IndicatorSetInteger" function. That function is used to set properties of an indicator, not to adjust the digits of a variable.
