Darvas Question

[higler]

I have a question that pertains to a number of indicators but Darvas is a good example of my misunderstanding. Among other things, Darvas returns a bool BuySignal and bool SellSignal. In some of my code I try the following:

if (Darvas(Close).SellSignal)
{
DrawArrowDown( etc.);
}

My problem is that I never get any DownArrows on my chart, at least on historical data. I haven't tried it on real time data.
My DrawArrowDown code statement is OK because if I substitute true in the if statement then I get down arrows.

I am wondering if I first need to check to see if my Darvas(Close).SellSignal contains a valid value before checking for true/false? If it doesn't contain a valid value then does my indicator throw an exception that prevents it from running properly?

Darvas().BuySignal returns a bool and not a BoolSeries and I was wondering if that is presenting a problem for me in my understanding since I can't use the [0] to reference the current bar? Thanks in advance for the help in helping me understand.

Hi higler !

The problem in the Darvas indicator is fixed and the fix will be available with the next update.

Thanks for reporting,

Can you tell me if the problem is in the Ninja Script code? Should it return a BoolSeries instead of a bool or is there something else? This question is just for my own edification because I am trying to understand the programming difference between an indicator returning a bool vs a BoolSeries and how I can use the return values and the useage in historical data vs real time data. Thanks.

The problem is with the Darvas indicator and not with your code. We will provide a fixed version with next NT update available in a few weeks.

Great, I can see someone else already posted on this. Looking forward to the fix. Thanks!
