Draw.Dot in Historical Bar

[turbofib]

hi, i try this code :

[COLOR=#add8e6]
 protected override void OnBarUpdate()
 [/COLOR][COLOR=#000000]{[/COLOR]
 [COLOR=#000000]if ( (Open[1]-Close[1])>0) 
     {
                    Draw.Dot(this, "D", true, 0 , Low[0]-TickSize, Brushes.Red);
[/COLOR]
  
 [COLOR=#000000]}[/COLOR]

but i see that it plot only last bar...
How i must do to solve it? (i want to plot all bar in historic)

Hello turbofib,

Thanks for your post.

Each drawn object requires a unique "tag name". In the example you are using the tag name of "D" for each object drawn. When you use the same tag name on successive objects what happens is that the current object is removed and the new object is drawn. In your case it would have repeated up to the last occurrence of the condition leaving just the last dot plotted.

To show all the dots, you will need a unique tag name for each one. One way to do this is to add the CurrrentBar to the name:

if ( (Open[1]-Close[1])>0) 
{
    Draw.Dot(this, "D"[COLOR="Blue"]+CurrentBar[/COLOR], true, 0 , Low[0]-TickSize, Brushes.Red);
}
