ATR Scaled Elhers Decycler For ThinkOrSwim


Well-known member
I whipped this up today, its a work in progress but already successful nonetheless. Arrows are the study's simple signals but there will be more complex ones to come.

Awesome. I am going to try it out. Is this better than your "Potential Breakout Arrow Plots Indicator" or a continuation of it?
Here is the code for the Arrows on this study, if you want it as a LOWER study.

plot up = if (decyclerosc[1] <= (min[1]+ .01)) and (decyclerosc >= min) then min else double.nan;
plot down = if (decyclerosc[1] >= min[1]) and (decyclerosc <= min) then min else double.nan;
plot sellup =  (decyclerosc[1] >= zeroline[1]) and (decyclerosc <= zeroline);

up.setPaintingStrategy(paintingstrategy.ARROW_UP) ;

Thank you for the indicator! Could you please include an identification (say a Dot or arrow) when the slope of the Decycler Oscillator changes from positive to negative or vice versa

I don't use this study but is this might work. Paste it to the bottom of your study:
plot uparrow = if  up  then low else double.NaN ;
uparrow.SetDefaultColor( ;

plot downarrow = if down   then close else double.NaN ;
downarrow.SetDefaultColor(color.magenta) ;
