Do not see the plot for indicator

[milindpaward]

Hello,

I am writing a custom indicator for learning purposes. I am creating RSI indicator that will draw RSI of higher timeframe. When I put the indicator on chart, I do not see any plot being drawn. I have attached code with this email. What am I missing?

Hello milindpaward,

Thanks for your post.

I see in your script that you are checking if (BarsInProgress != 1) and calling return. This is checking if the series that the script is processing is the added series and if not, calls return. If you remove this condition from your code so that the primary series is processed, the plot will display on the chart.

Please let us know if we may assist further.

Thank you Brandon. One more Question. My RSI is not showing only up to active range not total range. Please see the attached screenshot. It shows window from 34 tp 52.42. How can I make it from 0 to 100?

Hello milindpaward,

Thanks for your note.

You could override the OnCalculateMinMax() to set the minimum and maximum Y-Axis values. This method is used to determine the highest and lowest value that can be used for the chart scale.

See this help guide documentation for more information about using OnCalculateMinMax(): https://ninjatrader.com/support/help...lateminmax.htm

Let us know if we may assist further.

Thank you very much.
