F-Stoch v2 (Stochastic with Fib & Donchian)

F-Stoch v2 (Stochastics, Fibonacci, and Donchian Channels)
This indicator combines standard Stochastics with Fibonacci levels and Donchian Channels, enabling a multifaceted market analysis.
Note:
Some of the logic included in this script (specifically the calculation part for displaying Stochastics in Heikin Ashi style) was generated by AI (e.g., Google Gemini) based on user instructions.
Key Features:
* Customizable Stochastics: Freely set the %K and %D periods, smoothing, and offset.
* Fibonacci-based Trend Determination: Determines the trend (uptrend/downtrend/range) based on price position within the set Fibonacci high/low lookback period and reflects it in the Donchian Channel's background color.
* Donchian Channels: Applied to the Stochastic %K value, these indicate volatility and trend direction boundaries. There's an option for the Donchian Channels to change color in conjunction with the Fibonacci trend.
* Heikin Ashi Style %K Display: Provides an option to display the %K line in Heikin Ashi candlestick style instead of a regular line. This makes it easier to visually grasp changes in %K momentum.
This indicator offers a comprehensive toolkit for analyzing trend momentum, volatility, and potential turning points.
