牛熊周期 (Crypto Bull/Bear Cycle)

Indicator: Crypto Bull/Bear Cycle Pro Max

Overview

This indicator is a powerful visualization tool designed to help traders understand and analyze the long-term cyclical nature of the cryptocurrency market, which is widely believed to follow a four-year pattern.

It automatically colors the chart's background to provide an immediate macro perspective, distinguishing between pre-configured "Bull Market" years (green) and "Bear Market" years (red). Beyond simple coloring, this all-in-one tool includes a fully customizable countdown timer to the next cycle transition, annual separator lines, and extensive options to tailor the visuals to your personal preference.

Key Features

* **Automatic Cycle Coloring:** The chart background is automatically shaded green for bull years and red for bear years, giving you an instant sentiment check.
* **Cycle Transition Countdown:** A non-intrusive info box displays the exact number of days remaining until the next cycle is set to begin (e.g., from a bear to a bull period).
* **Annual Separator Lines:** Draws a clean vertical line at the beginning of each year, making it easy to compartmentalize and analyze yearly price action.
* **Highly Customizable:** Nearly every visual element is under your control. Adjust colors, transparency, text sizes, line styles, and fine-tune the positioning of the info box to perfectly fit your chart layout.
* **Future-Proof:** The cycle years are stored in an array within the code, which can be easily edited to add future years or adjust to your own cycle theory.

How to Use

* **Macro Perspective:** Use the green (bull) and red (bear) backgrounds to quickly assess the historical market sentiment for the period you are analyzing.
* **Long-Term Planning:** Keep an eye on the countdown timer to stay aware of major potential turning points in the market, which can be crucial for long-term portfolio strategy.
* **Yearly Analysis:** Utilize the vertical separator lines to easily measure and compare performance on a year-by-year basis.

**Note:** The bear years are predefined in the script's code on the line starting with `var int[] bear_years_array = ...`. By default, they are set to `2014, 2018, 2022, 2026,` etc. You can easily edit this line in the Pine Editor to add more years or modify the list if your cycle theory differs.
