Hello bandraguy,

The magenta lines are the Histogram series, which is the first series returned by the formula. It's series position in the return statement is 0, so you need to reference that series number with the setBarFgColor(Color, Series) parameter. Try adding the following code just before the return statement in main.

PHP Code:


    

    if(vMACD.getValue(MACDStudy.HIST)>vMACD.getValue(MACDStudy.HIST,-1)) {

        setBarFgColor(Color.lime,0)

    } else {

        setBarFgColor(Color.red,0)

    }

Difference b/w Two MACD

What is the difference between two MACD
files, 'builtinmacdcolorcoded(1)' and 'builtinmacd(hist color)2', which are on the forum.

Besides, color and thickness of lines, I see both files have different codes (script), but when plotted, both look the same.

Do these files plot simple moving averages (sma) or exponential moving averages (ema)?

Thanks for your prompt reply.

You may want to provide the links to the efs(s) you are referencing.

Both efs(s) are modifications of the builtinMACD.efs that is in the Builtin subfolder of Formulas and share the same functionality of the original. They can be set to use simple or exponential averages for either the MACD or Signal lines.
Builtinmacdcolorcoded.efs was originally posted in this thread and was modified at that time to color the MACD line in green when it is rising. In the version you posted code was added that also colors the MACD line in green if the Histogram is rising.
Builtinmacd(hist color)2.efs instead was originally posted in this thread and was modified at that time to color the Histogram in green if above 0 and in red if below. The option to display/hide the MACD and Signal or Histogram lines was also added. The code you posted is unchanged from that version.

MACD osc sma or ema

I am using the file 'builtinmacd(hist color)2.efs' to plot macd histogram, is this file using simple moving average (sma) or exponential moving average (ema) to plot macd signal.

If it is using sma, how do I change it to ema and vice versa.

Also, I have made some changes to change the color and thickness of the lines, can you check, if those changes are correct.

Thanks for your prompt reply.

To change the type of average used for the MACD and Signal lines go into Edit Studies and check the appropriate parameter
