What Could We Try Adding To This Code To Allow This

[birdog]

Hi folks,

What could we try adding to this code so that there is a selectable option in the indicator for when the line is green (movingup) and when the line is red (movingdown)?

This way we could use it, for example, as part of a strategy or filter is the reason.

Right now, I do not see an option to tell if it is going up or down in the options.



See attached.

Hello birdog,

"so that there is a selectable option in the indicator for when the line is green (movingup)"

I'm not clear on what you are asking.

Are you asking for selecting the color to be used for moving up?

Are you asking for an option for enabling disabling an alert when the line is green?

NinjaTrader_ChelseaB Thanks for asking here. Here is what the indicator looks like https://www.screencast.com/t/in3YNn3X (it is green when going up and red when going down). When adding it to a strategy there is no dropdown option to detect if it is green for going up or red if going down. See https://www.screencast.com/t/nEvOPvBP I am hoping to be able to get it to show a dropdown for so I can have it be used in a strategy. Like, if WSMA is green (i.e. going up) then .... etc. Or, if WSMS is red (i.e. going down) then... etc. Does that help? Again, thanks so much in advance! Greg

Hello birdog,

I still am not quite sure what you are asking..

there is no dropdown option to detect if it is green

A drop-down lets you select a value. How would this be used to detect something?

Are you saying you want to set a value, and then check the value in a condition in the code, and then in that condition action block check to see if the indicator is rising or falling.

Like, a checkbox for turning on and off some logic block in the code of OnBarUpdate()?

A drop-down does not detect things, so I am not understanding what you are trying to do.

NinjaTrader_ChelseaB On this, "Are you saying you want to set a value, and then check the value in a condition in the code, and then in that condition action block check to see if the indicator is rising or falling." Yea...exactly...so I might use it as a condition in the strategy builder.

You could add a Bool Series, set to true when moving up or false when moving down. Or an Int Series, 1 == up, -1 = down, 0 = flat. Make sure they are exposed for a strategy to see.

eDanny Thanks for the input. Do you mean adding a Int Series in the indicator or the Strategy Builder? Can you shoot me an example indicator or Strategy Builder settings on the attached? Or, just screenshots of settings would be fine to try. However, is easiest for you. See attached.

NinjaTrader_ChelseaB If you could see my other comments after you last one and my comms with eDanny, perhaps, if you would, chime in a bit more too perhaps?

Hello birdog,

You can add a public bool NinjaScript property and then require the bool to be true in the condition.

[NinjaScriptProperty]
public bool EnableCodeBlock
{ get; set; }

if (EnableCodeBlock == true)
{
if (Close[0] > Open[0])
{
// this code runs if EnableCodeBlock is enabled by the user and the other conditions also evaluate as true
}
}

You could also use an public enum for a drop-down and require the property to be equal to specific value.

Below is a link to an example.

NinjaTrader_ChelseaB Great...So, I can try adding this to the indicator code directly and then in the Strategy Builder, the options should be there to select? Or, are you meaning in the Strategy itself? If in the Strategy itself, would you mind to post screenshots of what I should input in a strategy in the Strategy Builder to allow the options to be used? Thanks a bunch! Greg

Hello birdog,

You can code in an indicator directly. You can also use the Indicator wizard from the NinjaScript Editor to add public inputs (properties).

In the Strategy Builder this would be added in the Inputs and Variables page.

Please watch the 'Automate Your Trading with NinjaTrader's Strategy Builder' training video which shows adding inputs on the Inputs and Variables page.

NinjaTrader_ChelseaB Hmm...can not seem to get it to compile with those two dropdown options. Could you add it as a example to this indicator attached?

If you have an error message you would like assistance with, provide the full error message and line of code causing the error and we are happy to assist.

That said, I have already provided a link to a reference sample in the help guide with an example drop-down enum input.

I am attaching here an example of a bool input added with the Strategy Builder.
