Convert a study into a histogram

[shakib3585]

Greetings all,

I would like to request that a study that I found useful be converted into a histogram. The study that I intend to convert into a histogram is as follows,

def cl = close(period=aggregationPeriod.THirty_MIN);

def op = open(period=aggregationPeriod.THirty_MIN);

def hi = high(period=aggregationPeriod.THirty_MIN);

def lo = high(period=aggregationPeriod.THirty_MIN);



def EM35 = MovAvgExponential(cl,35);



def haC = (op + hi + lo + cl)/4 ;

def haO = (haO[1] +haC[1])/2 ;

def haL = min(min(lo,haO),haC);

def haH = max(max(hi,haO),haC);



def Per_1 = (((hac[3] - haC)/haC)*100);

def Per_2 = (((EM35[3] - EM35)/EM35)*100);

def Histogram value = Per_1 + Per_2 ;

The color of the histogram should be in a similar pattern to that of a MACD. If the Histogram value is negative, the color should be red; otherwise, the color should be green. It should also be able to track histogram bars where the value has increased/decreased from its previous histogram bar (by changing the histogram bar colors just like MACD). I found it useful for tracing reversals. Any help is much appreciated.

Thank you,

Sha

Can you post the entire study?

The histogram style is really easy to implement.

Declare the indicator as a lower study and then use SetPaintingStrategy(PaintingStrategy.HISTOGRAM);

Hello @BenTen, the study is posted above

@shakib3585 I'm going to assume that you will be plotting the histogram based on your last condition (Per_1 + Per_2) since you didn't post the completed code.

Try this:

declare lower;

def cl = close(period=aggregationPeriod.THirty_MIN);

def op = open(period=aggregationPeriod.THirty_MIN);

def hi = high(period=aggregationPeriod.THirty_MIN);

def lo = high(period=aggregationPeriod.THirty_MIN);

def EM35 = MovAvgExponential(cl,35);

def haC = (op + hi + lo + cl)/4 ;

def haO = (haO[1] +haC[1])/2 ;

def haL = min(min(lo,haO),haC);

def haH = max(max(hi,haO),haC);

def Per_1 = (((hac[3] - haC)/haC)*100);

def Per_2 = (((EM35[3] - EM35)/EM35)*100);

plot data = Per_1 + Per_2 ;
data.SetPaintingStrategy(PaintingStrategy.HISTOGRAM);

Thanks a lot @BenTen . Can you please modify the code to change the color to red ( if negative ) and green (if positive). The green and red colors should also turn into dark green or dark red when the value starts to decrease/increase from previous

 

[BenTen]

Sure. Add this to the bottom of your script:

data.DefineColor("Positive and Up", Color.GREEN);
data.DefineColor("Positive and Down", Color.DARK_GREEN);
data.DefineColor("Negative and Down", Color.RED);
data.DefineColor("Negative and Up", Color.DARK_RED);
data.AssignValueColor(if data >= 0 then if data > data[1] then data.color("Positive and Up") else data.color("Positive and Down") else if data < data[1] then data.color("Negative and Down") else data.color("Negative and Up"));

Thanks a ton @BenTen
