Rays. Lines and bars

[ballboy11]

Is there a way in ninjascript to see if a bar crossed an angled ray object or line object?

Hello ballboy11,

Thanks for your post.

The CrossAbove and CrossBelow NinjaScript functions do not allow for comparing a Series or bar against a drawing object.

I would recommend using the anchor points for the line/ray and then using math to determine when the a cross happens between those data points and the high/low data points of a bar.

I went used some similar math in my Labeled Lines Drawing Tool extension, so the math there may be helpful for your needs.

Hello gplantis,

Thanks for your question.

CrossAbove/CrossBelow have an overload where you can specify an IDataSeries (like Close or Value) to see if it crosses a double.

// Go short if CCI crossed above 250 within the last bar
if (CrossAbove(CCI(14), 250, 1))
    EnterShort();

Let me know if you have any additional questions.

Hello gplantis,

I'm not exactly following here. When I test another indicator like an SMA crossing over a numeric value or test Close crossing over a numeric value, I do not have any issue.

Could you provide an example for what isn't working so I can give my input?

I look forward to being of further assistance.

Hello gplatis,

I'm glad you were able to resolve the issue on your end.

I've included a screenshot showing the prints.

If we modify the example to use EnterLong() instead of Print(), we would not be making an Apples to Apples test as there are internal rules that control how the order methods function. The condition could become true, but if we are already in a position and our strategy settings do not allow a new entry, we will see no action. Using Prints would be the sure fire way to check the logic alone.

Please let us know if there is anything else we can do to assist here.
