Draw Square why dissapear ?

[federicoo]

I want to draw a square on price chart each time that occurs an determinate event.

I'm using this:

DrawSquare("tag", true, 0, e.Price, Color.Red);

This works fine, but at each new event, when this instruction draw a new square, the last square on charts dissapear... I would like to keep all the squares drown before, is this possible? any idea?

Thanks

Hello federicoo,

Thank you for your note.

This is due to using the same tag ID. What you should do to make each DrawSquare unique is amend the "tag" name to something unique, for example,

DrawSquare("tag" +CurrentBar, true, 0, e.Price, Color.Red);

The code above should produce the behavior you want.

Please let us know if you need further assistance.
