    Performance problem with DrawRectangle

    I want to draw a zone arround horizontial lines (Pivot's)
    and use following code

    for (int i = 0; (i < base.Values.Length) && (base.Values[i].Count > 0); i++)
    {
    double value = base.Values[i][0];
    double yH = value + zoneSize * TickSize;
    double yL = value - zoneSize * TickSize;
    Color colorZone = Plots[i].Pen.Color;
    if( colorZone != Color.Transparent )
    {
    if( zoneShowAll )
    {
    DrawRectangle(
    string.Format( "Zone{0}_{1}", i, CurrentBar ),
    false,
    Displacement+1,
    yH,
    Displacement,
    yL,
    Color.Transparent,
    Plots[i].Pen.Color,
    zoneOpacity );
    }
    else
    {
    DrawRectangle(
    string.Format( "Zone{0}", i ),
    false,
    Displacement+width+1,
    yH,
    Displacement,
    yL,
    Color.Transparent,
    Plots[i].Pen.Color,
    zoneOpacity );
    }
    }
    }
    }


    Problem is that load of indicator is very slow.

    Any idea how to improve load time

    Klaus Hengher, if you use custom DataSeries - what MaxBarLookback option are you using?

    Do you need the historical drawn levels / rectangles here?

      Problem solved. Because pivots are constant for session I saved bar index on new session start and set id to actual session day+ index of pivot.This reduced drawed objects and improved load time significant
