The Draw.Line are deleted

[iradielt]

Hi, perform on an indicator.
2 Draw.Line and 2 PlotStyle.Triangle.
But when I see the historical one, I only appear in the last 2 lines. And the previous lines are erased.
The PlotStyle.Triangle. , they are not deleted.
How can I make it so that I can see the lines without being deleted?
Thanks.

if ((Close[1] > Open[1])&&(Close[0] < Open[0]))

Draw.Line(this, "tag1", false, 0, High[0]-(Canttics*TickSize), -2, High[0]-(Canttics*TickSize), Brushes.OrangeRed, DashStyleHelper.Solid, 2);

}
else if ((Close[1] < Open[1])&&(Close[0] > Open[0]))

Buys[0] = Close[0]+(distindi*TickSize);
Draw.Line(this, "tag2", false, 0, Low[0]+(Canttics*TickSize), -2, Low[0]+(Canttics*TickSize), Brushes.OrangeRed, DashStyleHelper.Solid, 2);
}
}

give them a distinct name "tag1"+CurrentBar instead of just "tag1", "tag2"+CurrentBar instead of "tag2",

Hello iradielt,

From the help guide:

"2. Set unique tag values for each draw object, unless you intend for new draw objects to replace existing objects with the same tag. A common trick is to incorporate the bar number as part of the unique tag identifier. For example, if you wanted to draw a dot that indicated a buying condition above a bar, you could express it:

Draw.Dot(this, CurrentBar.ToString() + "Buy", false, 0, High[0] + TickSize, Brushes.ForestGreen);"
