MACD Slope
Mar 4, 2019

The MACD Slope indicator measures the rate of change of the MACD line, signal line, and histogram to identify shifts in momentum and potential trend reversals before they appear in the standard oscillator.
Usage
The Usage of the MACD Slope indicator focuses on the velocity of price movement rather than just the absolute position of the MACD. Traders can interpret the slope values to gauge the health of a current trend:
- Improvement in Downtrend: A negative but rising slope suggests that while the trend is still bearish, the selling pressure is decelerating, often signaling a potential bottom or relief rally.
- Deterioration in Uptrend: A positive but falling slope indicates that bullish momentum is fading, suggesting a potential top or period of consolidation.
- Trend Confirmation: When both the MACD slope and the histogram slope are positive and rising, it confirms strong bullish momentum. Conversely, when both are negative and falling, it confirms strong bearish momentum.
- Signal Crossovers: The indicator includes a Signal Slope line. Crossovers between the MACD Slope and the Signal Slope can be used to identify early entries or exits similar to traditional MACD crosses, but based on the acceleration of the trend.
Details
The script calculates the standard MACD components using Exponential Moving Averages (EMA). To derive the slope, the script calculates the change in value over a user-defined lookback period and applies the arctangent function to convert the result into degrees.
To reduce noise and provide a cleaner visual output, the indicator applies a linear regression smoothing technique to the MACD and histogram slopes. This refactored version, originally based on code by @tmyerskerry, optimizes the calculations for better visual clarity and alert functionality.
Settings
- Fast Length: Determines the period for the shorter Exponential Moving Average used in the MACD calculation.
- Slow Length: Determines the period for the longer Exponential Moving Average used in the MACD calculation.
- Signal Length: The period used to calculate the EMA of the MACD line (the signal line).
- Lookback periods: Sets the distance over which the slope (change in value) is calculated.
- Smoothing: Adjusts the length of the linear regression used to smooth the slope lines, helping to filter out market noise.
FAQ
How do I interpret a falling positive slope? A falling positive slope indicates that the price is still generally moving upward, but the strength of that upward move is weakening, which often precedes a trend change or a flat market.
What is the significance of the zero line in this indicator? The zero line represents a flat slope. Values above zero indicate an upward-sloping MACD, while values below zero indicate a downward-sloping MACD.
