Multiple rectangle extension

[shildebrand324]

Hi, I have a script that prints rectangles on the chart based on certain rules. However, I'm having trouble with the logic on making them grow/extend as each new bar prints. Over the course of the day, there could be 20 or 30 rectangles on the chart. I need to extend each one until a price bar pierces the low of the rectangle.

Is there a way to do this?

Hello shildebrand324,

Re-use the signal name and you can re-draw the object. Using unique signal names will cause a new object to be drawn, instead of the existing object being modified.

You may want to save the CurrentBar of where you want the object to start, so that you can calculate the barsAgo for the start bar when re-drawing the object.
