Colored Horizontal Squares

[arb56]

Hi,

Is it possible in EFS to code an indicator study and have the results displayed in a subchart as a colored horizontal square - one per bar, and the color be based on the value of the indicator study? If so, can someone provide a coding sample?

Thanks in advance for your help!

Warmest Regards,

Andy

Yes. You can draw lines/box sets using the "drawLineRelative()" function or you can use the setBarBgColor() to change the backgound shading on the chart or you could try to use the "SQUARE" graphic object in EFS.

If you want to keep the graphics relative to price action and want to reset/clear any drawn object, it's probably better to stick with the graphics object for SQUARE or unique line draws to create a box.

The only suggestion I can make is to setup an array for all the drawn sets or objects so you can try to control them better.

edited : although. If you are looking for colored (shaded) boxes, then use setBarBgColor() with a control object.

setBarBgColor(Color.green,0, 12, 13);

// draw a green background between prices 12~13 on pane 0

Thank you Doji3333 and dloomis for your suggestions. I'll give it a try.
