Get all draw objects

May 12th, 2010, 10:13 AM

Hi All,

I need to enumerate all drawing objects on the chart that were created by some propriatary indicators ( I don't have access to source code). I need to get those strings, their tags and bar numbers.

Anyone knows how to implement this ?
Undocumented solutions will do.

Thank you.

foreach (ChartObject co in ChartControl.ChartObjects)
{
// do your stuff here
}

Hi,

with the above snippit i can't enumerate drawing objects, which were owned by other indicators. I want to enumerate triangles from an other indicator. How can i do that with Ninja 7?

Regards

"owned by other indicators"... without public exported ("strategy enabled") values, you dont have a warranty for stable results or the right sequence change/access on "drawing" only values...

Its work... while the NT7 databox use internal the same mothod to enumerate any indiactor plot values.

I had tried this script, but it will show only my user drawn objects. Do you have another solution or can you share your test script? Can an indicator lock any access from outside?

When I run co.ToString() I receive all information regarding the drawn objects. Unfortunately the .ToString() function displays for StartY & EndY only 2 decimal digits and this is not enough - especially for FOREX. Example:

'Line' Time='2/6/2015 12:30:00 PM', StartBar='1722' StartY='1.13' EndTime='2/12/2015 9:00:00 AM' EndBar='1907' EndY='1.13'

In real StartY is 1.12601 and EndY is 1.12685 - as you see the above values are totally useless in case I want to save all user drawn lines into the database and re-draw them once the user opens the chart again. This object is a raising line and the returned information lets believe it is a horizontal line.

Is there any chance how to get a more accurate value [at least 4 digits after comma]?

Thank you!

You could print individual elements and use the standard C# string formatting to get more places.

Sorry, but I don't understand how I should do it. In the IChartObject there is not any member for the Y values. Or what did you mean?

I assume there is a nested access route through the object list, but I haven't used it so may be wrong.

There is a Y object, try this:

Code

foreach (ChartObject co in ChartControl.ChartObjects)
{
    // do your stuff here
    Print(co.Y.ToString());
}
