As an experienced and highly qualified Pine Script developer, I know the ins and outs of TradingView like the back of my hand. My extensive nine years in the field, consistent track record of delivering top-quality work, and high Job Success Score distinguish me from other competitors. While my skillset may be currently distant from the description you cited, I have no doubt that my deep understanding of JavaScript will enable me to quickly understand and troubleshoot your Pine Script.
Throughout my career, I've developed a wide array of powerful TradingView indicators. Specifically, I've had great success with similar scripts that involve tracking highs/lows and drawing Fibonacci levels between them. In addition to resolving syntax errors effectively, I place significant emphasis on implementing intuitive, user-friendly customization options - meeting your script's requirement of customizable line colors, widths, and visibility will be second nature for me.
