Indicator proportional to another

[birdjaguar]

Perhaps I placed my concern in the wrong place. My request seems simple. I want to allow other indicators to move proportionally with one indicator that has an assigned value for optimization. For example, if I assign the value of 200 to a SMA, I would like the value of the RSI to be (SMA*.25). When the optimized value of the SMA changes, the RSI will also change without having to separately optimize it. Can anyone help me with this. I have searched the help files and videos and forums and internet to no avail. I simply want the value of the RSI to be (SMA*.25) once the value of the SMA is declared. Please advise.

Hello birdjaguar,

Thanks for your post.

It sounds like then you would want to set a user parameter for the SMA value and then in the code set your RSI to that variable * .25.

You may want to put some code in place to ensure that the RSI period would be no lower than some set minimum level. Such as RSI(Math.Max(5, value)) // uses the maximum of 5 or value if greater than 5.

Please see our reference information on creating user defined inputs:http://ninjatrader.com/support/forum...ead.php?t=5782

Thank you. I am familiar with creating user defined inputs. I have a user defined input for the SMA. That doesn't help me at all, with my question. Your interpretation of the question is correct.

"set a user parameter for the SMA value and then in the code set your RSI to that variable * .25."

Again, how can I set the value of the RSI to a fraction of the user defined input of the SMA?

Hello birdjaguar,

Thank you for your response.

Likely you have errors because creating a fraction of a whole value is likely creating a double value seeing as the value you multiply has a decimal.

So you need to take a few steps here. Based on the code you provided at the following thread I will provide an example below: http://ninjatrader.com/support/forum...ad.php?t=90904

			int RSIPeriod = Convert.ToInt32(SMAPeriod * .25);
			MySMA = SMA(SMAPeriod);
			MyRSI = RSI(RSIPeriod, 1);

I recommend reviewing our educational materials as you appear to be coming over from another charting platform's programming language (based on your code in the other thread).

Thank you for your response. I did peruse the educational resources to no avail. There was nothing there that actually helps with this code. I also tried your code to no avail, or maybe I just don't understand where it goes. I am at a loss as to why this is difficult and I am surprised that this has no come up before. Also, the "ConvertTo." syntax doesn't even come up in the search engine. How do I get from the following code to the RSI calculating as the SMA*.25?

#region Variables
int sMAperiod = 200;
int RSIPeriod = Convert.ToInt32(SMAPeriod * .25);

#region Properties
[Description("")]
[GridCategory("Parameters")]
public int SMAperiod
{
get { return sMAperiod; }
set { sMAperiod = Math.Max(1, value); }
}

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

Hello birdjaguar,

ConvertTo is C#, please provide your full indicator and I will show you how to add this in.
Your indicator file is located under Documents\NinjaTrader 7\bin\Custom\Indicators. Please attach to your response.

}

Remember to remove the public property for the RSI.
