Thank you for your response. I am already following everything mentioned in the tutorial. When I select the MT5 file, many options are automatically available. However, whenever I write code and then try to save it, the file saves as an MQ5 file, but the EX5 file gives an error due to the values of the predefined options and does not provide the file. I have now fixed it, but I do not understand why.

@sjthetechguy, Hi.How did you add the keltner to the my indicator.Can you explain

keltner has 3 value like bbbands .Low channel middle and up channel.I must be clear I guess.I just want apllied price and bandsmode option at my indicator section like bbands has on the picture.

Thank you for your interest. Yes, I used Keltner channel MQ5 files on MT5. I want to display the upper and lower channel values of the Keltner channel like the Bollinger indicator. I need to select the values I want from the upper and lower bands and compare them with another value. How can this be done?

I want the upper band and lower band options and all other features to be just like the default BBbands.
