MouseUp and MouseDown

[edward_bell]

Please help me on removing my drawn text when I scroll my mouse backward on the chart. Someone could help me on the MouseUp and MouseDown event on it.

Hello Edward,

Thank you for your post.

The MouseUp and Down events are unsupported with NinjaTrader but I will try to assist as much as I can.

What have you scripted thus far for the events?

Are using RemoveDrawObject(); in conjunction?

[edward_bell]

I am drawing a line

DrawLine("tag1" +CurrentBar.ToString(), false, xStart, yStart, xEnd, yEnd, Color.Lime, DashStyle.Solid, 2);

where xStart = 5; xEnd = 0; yStart = Low[5]; yEnd = Low[0];
then I have save the CurrentBar to xLine;

Now I will remove it using

xLineR = CurrentBar - xLine;

RemoveDrawObject("tag1" +xLineR);

It will remove when chart is in forward or the chart is running but if I scroll the mouse to go back or mouse down the line are still there unlike the plot series dots will be automatically remove/hide is scrolling back. Even my manually drawn line could not be remove by the remove code.

Can you supply the script so that I can test this out?

I could be wrong but I think you don't need "xLineR = CurrentBar - xLine;" and instead can just use RemoveDrawObject("tag1" +xLine);

When you save the CurrentBar you are saving the number of the bar. That is the number that is being added to "tag1". If you do some other math you won't be using the same bar number and that may be why your objects are not being removed.
