Non Numerical Indicators

[cdgardner]

I have been trying to convert the SuperTrend indicator to plot as a lower indicator based on color only without returning a numerical value. An example would be if the indicator on the price chart is showing price over plot and showing green, I would like have a lower indicator correspond with a green dot, block, or triangle that does grow and shrink with the spread represented on the price chart. Any help with this is appreciated.

Plotting dots, blocks, and triangles is quite possible. However, I don't believe that ToS will allow you to dynamically size the plot. You can change colors for a given plot, but not the shape either.

You would need to set up multiple plots, each of which had the properties you desired (as static properties) and give them a value of 0 when they are to show and double.nan when they are not.

so, as pseudo code (aka copy/paste this won't probably work), you could have

plot large_green_dot = if condition_for_large_green_dot then 0 else double.nan;
plot medium_green_dot = if condition_for_medium_green_dot then 0 else double.nan;
plot small_green_dot = if condition_for_small_green_dot then 0 else double.nan;

large_green_dot.SetPaintingStrategy(PaintingStrategy.POINTS);
medium_green_dot.SetPaintingStrategy(PaintingStrategy.POINTS);
small_green_dot.SetPaintingStrategy(PaintingStrategy.POINTS);

large_green_dot.setLineWeight(5);
medium_green_dot.setLineWeight(3);
small_green_dot.setLineWeight(1);

large_green_dot.setDefaultColor(color.green);
medium_green_dot.setDefaultColor(color.green);
small_green_dot.setDefaultColor(color.green);

From that, you could piece together a set of conditions for each of your combinations of shape/size/color properties and have your indicator... perhaps
