islocked

[frankduc]

Is it possible to apply

IsLocked to an indicator such as sampledisplaybarsago?

Everytime it is clicked on the chart the indicator is moving, i would like keep it still.

Now the code says:

public

override

void

OnMouseMove(ChartControl

chartControl,

ChartPanel

chartPanel,

ChartScale

chartScale,

Point

point)

{

if

(IsLocked)

//if the object is locked, do not attempt to move

return

;

I suppose you need to enter a bool in proprieties?

Hello frankduc,

Thanks for your post.

The script you have named is not an example I am aware of, but I did find an example my colleague Jesse has provided with the same name. Please be sure to include the script you are inquiring about so we can better understand how we can assist you.

The example specifically draws at a point fetched from ChartControl.MouseDownPoint, so after every time you click in a new location, the script is giving a new location to draw the text.

If you want the text to stay "still" you will want to control the coordinates where the text is drawn as opposed to using ChartControl.MousePointDown. I suggest viewing the SampleCustomRender example to see how it uses coordinates for ChartPanel to control where its custom drawing is placed on the chart.

Please let me know if you have any questions.

Sorry i dont see how what you explaining helps.

This is the script to move the indicator on the chart:

}
else if (State == State.Historical)
{
//add event handler
if (ChartControl != null) ChartControl.MouseUp += ChartControl_MouseUp;
}
else if (State == State.Terminated)
{
//remove event handler
if (ChartControl != null) ChartControl.MouseUp -= ChartControl_MouseUp;
}
}

private void ChartControl_MouseUp(object sender, MouseButtonEventArgs e)
{
//cause a refresh to poll after up click
ForceRefresh();


There must be a way to include islocked or change the mouse.up ? Like double clicking the chart to move the indicator. Is there a method for that?

Hello frankduc,

IsLocked is specific to DrawingTools. Locking down where you want something that is drawn with custom rendering so it does not move involves controlling your custom drawing to do so.

The MouseUp event handler calls ForceRefresh() when a mouse button moves to an upward position. This tells NinjaTrader that this indicator will need to process OnRender the next time the chart updates.

In OnRender, the example is setting the coordinates to the mouse coordinates and is drawing text at those coordinates. As you click on the chart, this coordinate changes, and the text location moves. If you don't want it to move, you will need to change the coordinates where the text is drawn to. Please see how SampleCustomRender draws "Lower Right Corner" starting at line 230.

Also, if your goal is simply to view BarsAgo values, I suggest enabling the crosshair and enabling BarsAgo indexes in your data box. (Open Data Box > Right Click > Show BarsAgo.)

I look forward to being of further assistance.

In vertical line you can go to the proprieties setting and click islocked box. In this case from the way i see it, from line 230, if i want to prevent the text from moving on the chart to keep it fix i will have to return everytime in editor to make the change in the coordinate. Nothing is simple with NT.

Hello frankduc,

VerticalLines are Drawing Objects, so they have the IsLocked property. If you are performing custom rendering you are telling NinjaTrader you want to take full control over where you want your drawings to be placed and how they should be drawn.

If this is too difficult, you could elect to use Drawing Tools like Draw.TextFixed. As this is a DrawingTool, the Drawing Object is lockable.
