How to get RSI Indicator with relative values?

[ASoellner]

Hello,
with the following code I get a wrong rsi value:

RSI rsi = RSI(Close, 14, 3);
double rsiValue = rsi.Value[0];

But the value is not relative from 0-100 and additional not top when bottom as in the diagram.

How can I get RSI like in the diagram?
14 and 3 are the default parameters out of the diragram.

Thanks
Andreas

Hello Andreas,

Thank you for your post.

Rather than using rsi.Value[0] you should be able to just use rsi followed by the barsAgo index you would like the value for:

RSI rsi = RSI(Close, 14, 3);
double rsiValue = rsi[0];

The help guide describes the following syntax to get the default RSI value:

Returns default value
RSI(int period, int smooth)[int barsAgo]
RSI(ISeries<double> input, int period, int smooth)[int barsAgo]

It looks like what you are doing is storing a reference to the indicator, which can have a performance benefit. This is useful when you are reusing an indicator several times throughout your code. That way you can call rsi[0] rather than RSI(Close, 14, 3)[0] for example. For a more detailed explanation of referencing indicator methods, please see the NinjaScript Best Practices page here:

Thanks for your answer.
I have change the code to without a reference.
RSI(14, 3)[0];

But I get still the same absolute values like 245000, 5149, ...
The diagram shows 0-100 values.

Hello ASoellner,

Thank you for your reply.

Do you get the same results with the attached indicator? I have created an indicator that prints the following to the NinjaScript Output window:

Print(String.Format("{0} RSI(14, 3)[0]: {1}, myRsi[0]: {2} rsiValue: {3}", Time[0], RSI(14, 3)[0], myRsi[0], rsiValue));

I tested it on the Playback Connection for ES 09-23 on 6/30/2023 and got output such as the following:
6/30/2023 10:00:00 AM RSI(14, 3)[0]: 57.1154920671089, myRsi[0]: 57.1154920671089 rsiValue: 57.1154920671089

I am not able to reproduce the results with the absolute values you have mentioned. Please import the attachment at Control Center > Tools > Import > NinjaScript Add On and test the indicator on a chart.

I look forward to hearing the results.

Hello Emily,

thanks for your help. Your example works. I have found my error.
RSI Indicator works as expected.

Thanks Andreas
