NinjaTrader 8 Indicator change from manual draw to automatic draw and re-draw

I have an existing NinjaTrader 8 Indicator that I have to manually select the start point and end point. And I would like to have it revised / altered to continuously draw and re-draw automatically. To complete this project you will probably need to be fairly familiar with programming for NinjaTrader 8. Details regarding the project are attached in 3 different formats, Images, PDF file, or a Video file. The original indicator that needs to be revised will be provided, to the Awarded Freelancer.
