Strategies and drawing objects

[Turtle Trader]

Hello,

Can a strategy create a drawing object?

I am trying to draw a ray within a strategy and it is not showing up on the chart.

I realize a strategy does not need a chart to be open, but if there is one open, can it create a drawing object?

If not, is there a technique to have a strategy tell a indicator to draw the object?

Thanks

Hi Turtle Trader,

Yes, this is certainly possible.

For example, by applying a strategy to a chart with...

DrawRay("Ray1",10, Close[0], 5, Close[0], Color.Blue);

Are you receiving any errors in the log tab of the Control Center?
Can you post the code snippet that you are using?

The missing piece: How do I attach a strategy to a chart?

Hi Turtle Trader,

You can right click and select "Strategies...".

I have the strategy running but the chart has "Strategy" greyed out. Cannot select it.

I am trying to test this with Replay Data....

Turtle Trader,

You will need to be connected to your replay first. Then please be sure that the Chart Trader is not on.

more questions

1) can a strategy be aware if I manually move one of the lines it creates
2) would it know the new coordinates of a line that was moved manually?
3) can it create more than one line and distinguish between them?
4) can it delete lines it has created?

Thanks

If yet, can you please point me to the correct references?

Hi Turtle Trader,

1. With NinjaTrader 6.5, you were limited in that you cannot move a line that a strategy creates. With version 7, you can, however...

2. You can collect that information.

3. You can create multiple lines by changing the tag name, for example...

"Line" + CurrentBar

4. You can remove lines with RemoveDrawObject()
