Bias Detector Terminal [The Quant Science]

Bias Detector Terminal is a quantitative analysis tool designed to identify day-of-week statistical bias and seasonality. By calculating the historical frequency of bullish closes for each trading day, the terminal provides a clear picture of directional market probabilities.



🔷 What it does
The indicator analyzes daily price history to calculate:

1. Bullish Ratio: The number of bullish sessions (close > open) relative to total historical bars for each day of the week (Monday to Sunday).
2. Session Win Rate: The exact percentage of positive closes for every trading day.
3. Smart Bias Signals: Categorizes each session based on statistical thresholds:
   
   • 🟢 [ BULLISH ]: Win Rate >= 55%
   • 🔴 [ BEARISH ]: Win Rate <= 45%
   • ⚪ [ NEUTRAL ]: Win Rate between 45% and 55%
4. Visual Flow Profile: An inline progress bar for instant visual assessment of buy/sell pressure.
5. Composite Metrics: A summary row showing the cumulative baseline for all historical data analyzed.

🔷 How to use it

• Chart Application: Add the script to the chart of your chosen asset (Stocks, Crypto, Forex, Indices).
• Timeframe Setting: Make sure the chart is set to the Daily (1D/Daily) timeframe. The script includes a built-in check that will trigger an error if applied to lower timeframes.
  

🔷 Interface Customization
Through the indicator settings you can:

• Change the console position on screen (Top Right, Top Left, Bottom Right, Bottom Left, Center).
• Modify the terminal font size (Small, Normal, Large).

🔷 Use Cases

• Weekly Operational Planning: Identify in advance which days of the week historically favor buyers or sellers from a statistical standpoint.
• Confluence Filter: Avoid opening short positions on days with a historically high bullish win rate (and vice versa), raising the overall quality of your trade setups.
• Seasonality Analysis: Determine if a specific asset exhibits recurring statistical patterns (e.g., Turnaround Tuesday or Friday weakness).

🔷 Target Audience

• Quant & Systematic Traders: For those who base their decisions on statistical data rather than gut feeling.
• Day Traders & Swing Traders: Useful for aligning intraday operations with the statistical trend of the current day.
• Market Analysts: For those who want to integrate high-level visual reporting and quantitative metrics into their TradingView analysis.
