Indicator awareness of manual drawn lines

[Turtle Trader]

Is there a way in NT7 for an Indicator to know of a hand drawn ray, horizontal, or vertical line?

And, to get at least two coordinates on that line?

thanks

Hello,

Thank you for your forum post.

This is possible please see the below guide on how to do this:

You will want to use the sample code at the bottom to loop through all objects on the chart and then there is a parameter there you can check as well for if its userdrawn.

Let me know if I can be of further assistance.

Hi Brett. Is there any facility for doing this in 6.5?

Hi,

Don't believe this is available, however you might want to take a look here and see if you can find something about it:

Use the arrows in the upper right corner to scroll through the documentation.

How does the drawObject work? Will it allow you to access indicator values on a chart you're currently displaying? For example if I've drawn an SMA(20) on a 6J 03-11 chart which has the label SMA_20, is it possible to start programmatically grabbing values from that specific chart?

JayJoshi, can you please be more specific? If you take a look at the code at the bottom of the page linked to by Brett in post #2, you will see how to loop through the draw objects on the chart. You can then grab the values of whatever draw object you wish. So in short, yes, it is possible to access indicator/draw object values on a chart the indicator is on.

Thanks Austin.

I threw up a chart (File --> New --> Chart) and stuck two SMA's on there and ran the simulated feed. Then I created a simple strategy with the wizard and used the 'foreach' loop sample to unlock the draw objects. I also put a print statement in the foreach loop to make sure the loop was being reached but nothing was written to the Output Window when i ran the strategy for the same symbol.

I think I'm missing a step somewhere that links the chart itself that I built to the actual strategy code. Is there an end-to-end tutorial on how to link a chart to a strategy?

JayJoshi, I should have been more specific. Indicator plots are not draw objects. To get those values, you will have to reference them directly:
currentSMA = SMA(14)[0];

Draw objects are items such as dots, diamonds, squares, lines, etc.

Once you apply a strategy to a chart, you must make sure it is enabled. Then they are "linked" and the strategy is running on the chart data.
