Getting trend line value in strategy

[AlgoNaute]

Hi all,

is it possible to retrieve graphical object values in strategy, especially trend line?

My objective is to send orders when price cross some trend lines I set up manually.

I know this is possible on other platforms but is it possible on NinjaTrader?

Many Thanks!

AlgoNaut,

Yes, this is possible.

For example, if you use :

IRay trendLine = DrawRay("tag1", 10, 1000, 0, 1001, Color.LimeGreen);

You can access the "trendLine" object the following way :

trendLine.Anchor1BarsAgo  //An int value representing the number of bars ago of the 1st anchor point

trendLine.Anchor1Time  //A DateTime structure representing the time of the 1st anchor point

trendLine.Anchor1Y  //A double value representing the y value of the 1st anchor point

trendLine.Anchor2BarsAgo  //An int value representing the number of bars ago of the 2nd anchor point

trendLine.Anchor2Time //A DateTime structure representing the time of the 2nd anchor point

trendLine.Anchor2Y   //A double value representing the y value of the 2nd anchor point

trendLine.Pen   //The Pen object used to draw the object

Thanks a lot for your help.

Do we need to draw it on the strategy and then modify it manually or can we first draw it manually on the chart and use these lines afterr on the strtaegy (thanks to the tag number for exemple).

AlgoNaute,

The example I gave you would only work for programmatically drawn objects without an extra step. If you want to use manually drawn objects you need to be able to grab the IRay objects on your chart, identify the one you want the strategy to use by tag, then you can modify it or access its internal variables.

Here is a sample of an indicator that alerts you when the price crosses a manually drawn line.

You could adapt this for your purposes into a strategy.
