With over a decade as a full stack engineer, I have garnered an extensive repertoire of skills that have helped me excel in diverse software development tasks. Specifically, my experience also extends to your project’s domain, Pine Script. As a trading developer, I've been immersed in developing with TradingView (including Pine Script), Thinkorswim by thinkscript, Metatrader 4 and 5 in MQL 4 and MQL 5 and Ninjatrader7/8 by Ninjascript, among others.
In terms of your requirements of developing an indicator using daily ATR projections and incorporating day separators and labels, signs that I'm capable of not only being responsive to your needs but also delivering on innovative solutions are visible in my completion of over 80 web and mobile application projects, where I've acted as the architect, project lead, or as a full stack developer.
I am eager to leverage my experience and expertise to produce unique solutions that will help you make more informed trading decisions and further enhance my understanding of Pine Script. Being detail-oriented while keeping the big-picture vision intact has always been my strength; I don’t just write code - I weave calculated functionality into it. Cheers!
