    Drawings stuck on chart NT7

    I have an indicator which draws horizontal lines on the chart
    and when I go to change my indicator settings the lines should dissapear
    but they just get stuck on the chart and the only way to get rid of them is to
    reload historical data.

    Any ideas on a fix?

    Thanks Patrick.
    I figured out my problem.
    I was overloading the dispose function while not removing those drawings in that function

    Hello trader3419,

    Thank you for your patience.

    In testing your DrawRay() syntax, the object is removed when the indicator is removed. Attached is my test, are you performing anything different such as looping through the IDrawObjects or anything else?

    Here is an example

    DrawRay("tag7",false,0, entryprice,1,entryprice, Color.White,DashStyle.Dash,1);

    Hello trader3419,

    Can you provide the lines of code for each object?

    I use only DrawRay() and DrawText()
    These objects get stuck on the chart after I change my indicator settings
    Why isn't it disposing of the old drawing objects?

    Hello trader3419,

    Thank you for your post.

    Upon a reload of NinjaScript after altering settings it should recalculate just as reloading historical data would force the instrument to recalculate
    Do you use specific tag strings for each drawing tool? Can you provide an example of a drawing tool method in your code that does not change after changing the settings in the indicator?

    I look forward to your response.
