FlatTrend Alert
Download script
The Flat Trend Alert is a specialized technical analysis tool designed to help traders identify specific momentum shifts and periods of market stagnation. By utilizing the MACD (Moving Average Convergence Divergence) indicator, the script filters out standard market "noise" to highlight three distinct market states visually in a dedicated window.
How the Logic Works
The script analyzes price action based on the timeframes you select (ranging from 1-minute charts to monthly views). It processes historical data to categorize market movement into three primary signals:
- Bullish Momentum (Blue Signal): The tool identifies conditions where the MACD Main line is above zero and crossing over its signal line. This represents an active upward trend, which the script highlights in Royal Blue.
- Bearish Momentum (Red Signal): Conversely, the tool tracks when the MACD Main line falls below zero and crosses under its signal line. This indicates downward momentum and is highlighted in Red.
- Flat/Neutral Market (Gold Signal): One of the script's key features is its ability to detect "flat" markets. If the price action is neither showing active bullish nor bearish momentum, the script flags this as a neutral zone, displayed in Gold.
Automated Alerts
Beyond visual representation, the script acts as an automated monitor. It tracks real-time changes in these market states and triggers immediate audible alerts on your platform:
- A "Blue color show up" alert sounds when the market shifts into a bullish trend.
- A "Red color show up" alert sounds when the market shifts into a bearish trend.
By distilling complex moving average calculations into three clear visual cues, this tool allows you to quickly distinguish between active trends and consolidation periods at a glance.
