RSI Alert

[bougie]

Hi, I just want a sound alert once the lower or upper limits have been crossed. LineAlert would do the job, as I could just draw the line manually, unfortunately, it seems to only work on price bars, and not the RSI upper and lower lines.

Thanks.

Hello bougie,

I'm not aware of an existing indicator that does this, however it would be possible with custom programming.

NinjaTrader is based on the modern C# programming language which allows advanced charting that is extensible in that you can create custom indicators using NinjaScript.

* Click here for information on programming in NinjaScript

You would want to use the Alert() method based upon the condition that you would like.
http://www.ninjatrader.com/support/h...html?alert.htm

For Example:

if(CrossAbove(High[0], RSI(20, 3),1) || CrossBelow(Low[0], RSI(20, 3),1))
				Alert("myAlert", NinjaTrader.Cbi.Priority.High, "RSI Alert", "Alert1.wav", 10, Color.Black, Color.Yellow);

Let us know if we can be of further assistance.

hi, sorry i have no experience with coding. Do i copy and paste that line of code into rsi.cs?

Hello bougie,

Thank you for your response.

You would not paste this into the RSI but would follow the instructions below to create a new indicator with the code that JC provided.

• Go to Tools > New NinjaScript > Indicator
• Next
• Name the indicator and select Generate
• Then paste the code JC created into the OnBarUpdate() method
• Then press F5 compile

Once complete you code should look like the following:

        #region Variables

        #endregion

        /// <summary>
        /// This method is used to configure the indicator and is called once before any bar data is loaded.
        /// </summary>
        protected override void Initialize()
        {
            Overlay				= false;
        }

        /// <summary>
        /// Called on each bar update event (incoming tick)
        /// </summary>
        protected override void OnBarUpdate()
        {
            if(CrossAbove(High[0], RSI(20, 3),1) || CrossBelow(Low[0], RSI(20, 3),1))
				Alert("myAlert", NinjaTrader.Cbi.Priority.High, "RSI Alert", "Alert1.wav", 10, Color.Black, Color.Yellow);
        }

        #region Properties

        #endregion

We have a fully documented help guide which will help you get started with Ninja Script. You will find language references to all of the methods and functions you will be using. You will also see a tutorial section which will help you create your first indicator and get you started with some of these concepts.

I've tried pasting it, getting many errors, maybe not pasting in right section of code?

[Radical]

Did you make any modifications to the original @RSI.cs file? Those errors are in the @RSI.cs file, not the file that you have open in that window.

[bougie]

I tried to paste it originally into rsi.cs... might have screwed up that file possibly, how do I replace the original rsi file now?

[Radical]

Try opening the @RSI.cs file, deleting everything in it (so it's completely blank), then paste the below code into it:

That was taken directly from my stock @RSI.cs file.

ok, tried that, now getting this:

[koganam]

I've tried pasting it, getting many errors, maybe not pasting in right section of code?

[ATTACH]23554[/ATTACH]

That shows errors in the shipping NT system indicator. It is hard to see how you could have such an error unless you edited the file outside of the NT editor, as the NT editor would not save any changes to NT system files. As it is hard to know what else may now be corrupted, you would be best off reinstalling NT, then following the instructions that were so clearly written by NinjaTrader_PatrickH.

thank you, problem resolved

Hello, I am trying to find an alert on the RSI on the crossover do you have any information on that procedure?

[NinjaTrader_Jesse]

Hello boldhead,

Welcome to the NinjaTrader support forums.

Assuming that you are not doing the same steps which the original poster had you should be able to just copy the syntax from post #2 into a new indicator or strategy to make an alert from the RSI. The other content in this thread is related to the users specific situation and will not likely apply toward your situation.

You can learn more about this syntax from the help guide:

https://ninjatrader.com/support/helpGuides/nt7/alert.htm?zoom_highlightsub=alert

https://ninjatrader.com/support/helpGuides/nt7/relative_strength_index_rsi.htm?zoom_highlightsub=rsi

I look forward to being of further assistance.

[boldhead]

Hi Jessie. I looked over there information how do I take this information and put it into a crossover alert for the RSI?

[NinjaTrader_Jesse]

Hello boldhead,

The information in this post is for NinjaScript, so this assumes that you are developing a strategy or indicator already. Once you have created a strategy or indicator, you could utilize the syntax from post #2 to form an alert. The syntax is complete in that post, you would just need to make your script look the same to start working with alerts.

I look forward to being of further assistance.
