Quality Detector (Buffett Style) + Beta [Solid]

This indicator acts as an on-chart fundamental screener, designed to instantly evaluate the quality and financial health of a company directly on your price chart.

The concept is inspired by "Buffettology" principles: looking for large, profitable companies with low debt. Additionally, it includes a Beta calculation to assess market volatility risk.

The tool displays a panel in the bottom-right corner featuring four key metrics and a final verdict.

How it Works & Metrics Used
The script retrieves quarterly fundamental data ("FQ") and performs calculations to verify if the asset meets specific criteria.

1. Market Cap (Size)

What it is: The total market value of the company's outstanding shares.

Goal: To identify established, large-cap companies.

Default Threshold: Must be greater than $10 Billion.

2. ROE - Return on Equity (Quality)

What it is: A measure of financial performance calculated by dividing net income by shareholders' equity.

Goal: To find companies that are efficient at generating profits from shareholders' capital.

Default Threshold: Must be higher than 15%.

3. Total Debt to Equity (Health)

What it is: A ratio indicating the relative proportion of shareholders' equity and debt used to finance a company's assets.

Calculation: This script manually calculates this ratio by fetching TOTAL_DEBT and dividing it by TOTAL_EQUITY from fundamental data to ensure robustness across different symbols.

Goal: To ensure the company is not overly leveraged.

Default Threshold: Must be lower than 1.5.

4. Beta (Risk/Volatility)

What it is: A measure of a stock's volatility in relation to the overall market (S&P 500).

Calculation: It is calculated by comparing the asset's returns against SPY (S&P 500 ETF) returns over a 252-day period (approx. 1 trading year).

Goal: To understand if the stock is more volatile (Beta > 1) or less volatile (Beta < 1) than the market.

Note: Beta does not affect the final "Quality" score but serves as an extra risk indicator, highlighting in orange if Beta > 1.

The Verdict (Scoring System)
The indicator assigns a score from 0 to 3 based on the first three fundamental metrics (Size, ROE, and Debt/Equity).

If a metric passes the threshold, it gets a green background and +1 point.

If it fails, it gets a red background.

Final Verdict:

💎 QUALITY GEM: The company passed all 3 fundamental checks (Score = 3/3).

⚠️ DISCARD: The company failed one or more fundamental checks.
