How to create spread/ratio charts.

[yellowTrader]

I am trying to create a chart which is a derivative of the original chart i.e. I simply need to subtract,add, divide,... the values of each bar by a certain number to create a new derivative chart.
Or if that's not possible , I want to create an indicator which shows the last price of a security added, divided,.... by a specific number.
Is there any codes written for this job in your archives? If not , how do I go about this?
Thanks.

yellowTrader,

You can search through the File Sharing section to see if you can find anything. If not, you will need to custom program this yourself. Alternatively, you can also try one of the 3rd party NinjaScript Consultants here: http://www.ninjatrader.com/webnew/pa...injaScript.htm

To program this is just a matter of taking your price and subtracting your value. Please see this tutorial on creating custom indicators: http://www.ninjatrader-support.com/H...tml?Overview23

Plot0.Set(Close[0] - value); something like that.

I did exactly as you said but it gives me CS0120 error code. I tried looking up the code to find the problem but it says" No Documentation Available" on this error code.
What is wrong with the code below?
Plot0.Set(Close[0] - 11);

You can't copy paste it. It was just an example and you have to make it work with your code. You likely do not have a plot named Plot0. If you create an indicator with the Indicator Wizard you will have Plot0 by default.

I didn't copy paste it. I created an indicator and I have Plot0 by default.
The file attached shows the entire picture.

yellowTrader,

The orange in the compiler error signifies this is an error in a different file. Please double click on it to see the error in the other file. You will need to address all errors across all NinjaScripts before you can compile.

Thanks Josh. I fixed it.
Can you send me a link for Mathematical functions like division , multipication, etc...?
