This TradingView Pine Script implements the Cloud indicator, which consists of several components to analyze market trends. It calculates the Tenkan-sen (conversion line) and Kijun-sen (base line) using Donchian channel averages over specified periods. Additionally, it computes two leading spans to create a cloud (Kumo) that visually represents support and resistance levels. The script plots these lines on the chart, including a lagging span that follows the price. The cloud's fill color changes based on the relationship between the leading spans, indicating bullish or bearish conditions.
