draw objects display

[tron305]

Hallo,

I need to add some script into the existing one to change the settings of the draw objects display.
They are displaying "Calculate on bar close - false" right in the moment of creation (the conditions are executed) - it's ok.
But I also need to add the script to remove the drawing object right in the moment of termination (in case the conditions are no longer executed) before the price bar will be closed.

Thank you for your help,
Richard

Hello,

Thank you for your forum post.

In this case you would need to run the Strategy in Calculate on Bar Close = False.

Then move all your COBC = True logic in your indicator code to if(FirstTickOfBar)
{
//You OnBarUpdate code here, this works in COBC = True mode.
}


Then outside of this you will add your code to delete the drawing objects if the conditions are no longer true, this will execute on every tick allowing you to remove the drawing object if the condition was no longer true.

Another method to do this if you dont want the objects deleted at the first sign of the conditions no longer being true, would be to check this on the creation of the next bar weather or not the previous bars conditions where true and remove the drawing objects if they are not true. Best way to do this would be with a boolSeries.

Let me know if I can be of further assistance.

... I have thought about ang got solution. Is it correct?
thanks for advice.

protected override void Initialize()
{
CalculateOnBarClose = false;
}
protected override void OnBarUpdate()
{
// Condition set 1
if (//some conditions)
{
DrawTriangleUp("My triangle up" + CurrentBar, false, 0, Low[0] + -10 * TickSize, Color.Lime);
DrawText("My text up" + CurrentBar, "0/v", 0, Low[0] + -15 * TickSize, Color.DimGray);
}
// Condition set 2
else if (//some conditions)
{
DrawTriangleDown("My triangle down" + CurrentBar, false, 0, High[0] + 10 * TickSize, Color.Crimson);
DrawText("My text down" + CurrentBar, "0/v", 0, High[0] + 15 * TickSize, Color.DimGray);
}
else
{
RemoveDrawObject("My triangle up" + CurrentBar);
RemoveDrawObject("My text up" + CurrentBar);
RemoveDrawObject("My triangle down" + CurrentBar);
RemoveDrawObject("My text down" + CurrentBar);
}
}

Hello,

Does it run as you expect live?

There are always 10 different ways to do things in coding Looks like it should work though.

Let me know if I can be of further assistance.

This is the final output, just for accuracy.

protected override void Initialize()
        {
            CalculateOnBarClose = false;
        }
protected override void OnBarUpdate()
        {
            // Condition set 1
            if (//some conditions)
            {
                DrawTriangleUp("My triangle 0v up" + CurrentBar, false, 0, Low[0] + -10 * TickSize, Color.Lime);
                DrawText("My text 0v up" + CurrentBar, "0/v", 0, Low[0] + -15 * TickSize, Color.DimGray);
            }
			else

				RemoveDrawObject("My triangle 0v up" + CurrentBar);
				RemoveDrawObject("My text 0v up" + CurrentBar);

            // Condition set 2
