public input

How to I make an input available from my custom indicator?

I have a simple indicator called myADX with only 1 input called period. How do I make myADX and period callable from other strategies and indicators?

double = myADX( period )[0];

Thank You - Westsider

Hello Westsider,

That looks good. To call your indicator you will just need to use the Class name and any overloads that it requires so since you only have 1 parameters then you would just need to pass it in one parameter like "period". You will just have to make sure that it is the same type like an "int".

Here is an example of how to call an indicator from a strategy which would be the same way you may call it from another indicator as well from the following link.

Note that if you have not created a strategy before using the Strategy Wizard will help you get started with this and may help you out with your Indicator as well. I'm proving a link to a recently recorded 'Automated Strategy Development Webinar' video for you to view at your own convenience: http://youtu.be/SpwGTr9kl9k

Hi JC,
Thanks for the info. I have used the strategy wizard and its great. The problem I'm having is period does not show up when I call it from a strategy.

I was creating the input "period" manually and it was not public. When I use the Indicator wizard and it creates the input "period". It is available when called from a strategy.

The wizard must do something different in the background because I manually create the properties the same way.

private int period = 5;

[Description("")]
[GridCategory("Parameters")]
public int Period
{
get { return period; }
set { period = Math.Max(1, value); }
}

Is that correct?

Thanks - Westsider

Hello Westsider,

That looks correct. Is that the code for the "Period" variable that you are defining inside of your Strategy or Indicator?
