Trend Reversal Indicator (EMA of slopes)
Jan 23, 2021

The Trend Reversal Indicator (EMA of slopes) indicator provides a specialized approach to trend analysis by calculating the rate of change, or slope, of various technical sources to identify potential market reversals. By applying moving averages to these slopes rather than direct price data, the tool highlights shifts in momentum and decisiveness that often precede significant trend changes.
Usage
The tool is primarily used to anticipate trend reversals by observing the relationship between a fast and slow moving average calculated from the source's slope.
- Trend Reversal Identification: A bullish reversal is signaled when the fast moving average (default blue) crosses above the slow moving average (default red). Conversely, a bearish reversal is signaled when the fast moving average crosses below the slow moving average.
- Momentum Analysis: The indicator offers three primary visualization modes:
- Moving Averages: Standard dual-average crossover logic applied to the slope.
- Z-Score: Normalizes the slope values to identify extreme deviations and mean-reversion points.
- Stochastic: Applies a stochastic oscillator to the difference between the averages to identify overbought or oversold momentum conditions.
- Strategic Integration: Users often combine this indicator with price-based EMAs to establish a general trend bias, or with traditional oscillators to time entries within overextended zones.
Details
The indicator functions by first calculating the "slope" of a selected source (EMA, Stochastic K, Stochastic D, or RSI). This slope is an approximation of the first-order derivative, calculated by dividing the variation of the series by its last value.
Because traditional indicators are derived from price, the steepness of their movement reflects the aggressiveness of market participants. By analyzing the slope via dual moving averages, the script captures the acceleration and deceleration of price action. The inclusion of a Z-Score calculation allows for statistical normalization, making it easier to spot outliers in momentum across different timeframes.
Settings
- Source Type: Choose between EMA, Stochastic K, Stochastic D, or RSI as the primary data source for slope calculation.
- Moving average applied on slope: Select the smoothing method (EMA, SMA, HMA, WMA, etc.) for the fast and slow averages.
- Length ema-slope (FAST/SLOW): Adjust the periods for the two primary trend-detecting averages.
- Use linear regression on EMA FAST?: Toggles a linear regression filter on the fast average to reduce noise.
- Plotter (Show Slope/MAs/Zscore/Stoch): Select which visualization mode to display on the chart.
- Z-score Settings: Configure the observation period and moving average type used for the statistical normalization.
- Stochastic Settings: Adjust the lengths for K and D lines when using the Stochastic visualization mode.
FAQ
How do I interpret the Z-Score circles?
The green circles indicate a Z-Score crossing up while below zero (potential bullish momentum shift), while red circles indicate a crossing down while above zero (potential bearish momentum shift).
Which source is best for trend reversals?
While it depends on the asset, the RSI or EMA sources are commonly used for general trend identification, whereas Stochastic sources can be more sensitive to short-term momentum shifts.
