Custom Instument

[David Hill]

Hi

I wish to create a chart with a Custom Instument to give me the p/e ratio of the sp500 index. The problem is I need to put in a static number, presently around $250.00, to use in the instument and then "pair" it with the sp500 index to give me the ratio. I don't know how to do this. Can anyone help ?

Thanks

David.

Hello David,

A custom instrument would not allow you calculate data. Instrument data has to come directly from the connected data provider.

Instead, I recommend you create an indicator.

Below are links to indicators in the User App Share that calculate a value from an underlying instrument.

Hi

Thanks, but how do I get a static number into these ?

Hello David,

You could hardcode the value into the script code.
You could make an input and type in a value.
You could read a value from a text file.
You could calculate a value..

How do you want to put the value in?

As an example of an input:

[NinjaScriptProperty]
[Display(Name = "My Static Number")]
public double MyStaticNumber
{ get; set; }

Hi,

Sorry, I don't know coding. I just would like to be able to input into a box, the static number, and pair it(ratio) with an instrument, in this case the SP500, and have it create an instrument (or indicator) I can chart in Ninja as any other instrument.

Thanks,

David

Hello David,

Unfortunately, this would not be possible without creating an indicator to do so.

The spread indicator I've provided a link to allows for a multiplier on one of the instruments if this helps.
