Performance with Okuninushi Line Area Determinations

**Performance Indicator with Market Structure Analysis**

Building upon TradingView's official Performance indicator, I've added a custom column to assess current market structure using my Okuninushi Line methodology, which visualizes the AB structure concept.

**What is the AB Structure?**

The AB structure identifies equilibrium levels based on recent price action. The Okuninushi Line calculates the 50% midpoint between the highest high and lowest low over a specified lookback period. In this implementation, I use a 65-day period on the daily timeframe (representing one quarter: 13 weeks × 5 trading days), though this is fully customizable.

**Market Structure Classification:**

- **Above Okuninushi Line** → "upper to okuni" → Price is in the **Premium Area** (bullish structure)
- **Below Okuninushi Line** → "down to okuni" → Price is in the **Discount Area** (bearish structure)

This additional column provides an instant visual reference for whether each asset is currently trading above or below its equilibrium level, complementing the traditional performance metrics with structural context.
