Updated Daily Bias with Linear Regression

Overview
The Daily Bias with Linear Regression is a trend-following tool designed to help traders identify the prevailing market direction by aligning the momentum of two critical timeframes: the Daily (D1) and the 4-Hour (H4). By using Linear Regression slopes, this indicator filters out market noise and provides a clear "Bullish," "Bearish," or "Neutral" signal.
How It Works
The indicator calculates the slope of price action using Linear Regression over two specific periods:
The Daily Bias is determined as follows:

How to Use
The Daily Bias with Linear Regression is a trend-following tool designed to help traders identify the prevailing market direction by aligning the momentum of two critical timeframes: the Daily (D1) and the 4-Hour (H4). By using Linear Regression slopes, this indicator filters out market noise and provides a clear "Bullish," "Bearish," or "Neutral" signal.
How It Works
The indicator calculates the slope of price action using Linear Regression over two specific periods:
- Daily (D1): 20-period lookback.
- 4-Hour (H4): 18-period lookback.
The Daily Bias is determined as follows:
- 🟢 BULLISH: When both the D1 and H4 slopes are positive.
- 🔴 BEARISH: When both the D1 and H4 slopes are negative.
- ⚪ NEUTRAL: When the slopes are conflicting (e.g., D1 is up, but H4 is down).
Key Features
- Multi-Timeframe Analysis: Automatically fetches data from higher timeframes (D1 and H4) to provide a macro perspective even if you are on a lower timeframe.
- Anti-Repaint Logic: The script is coded to fetch the slope of the *previous* closed bar, ensuring that the signals remain stable and do not repaint.
- Real-time Dashboard: A clean table in the top-right corner displays the current ticker and the live bias status.
- Visual Labels: Direct "Bullish" or "Bearish" labels are plotted on the chart for immediate visual confirmation.
- Timeframe Guard: Includes a built-in warning if the chart timeframe is set below 1-Hour (H1), as the indicator is optimized for higher timeframe confluence.
How to Use
- Trend Confirmation: Use the "BULLISH" or "BEARISH" status to align your trades with the higher timeframe momentum.
- Filter: Avoid taking long positions when the bias is "BEARISH" or short positions when it is "BULLISH."
- Wait for Alignment: A "NEUTRAL" bias suggests a ranging market or a potential trend change; waiting for both timeframes to align can increase trade probability.
