L2 Bull-Bear Momentum
Nov 16, 2022

The L2 Bull-Bear Momentum indicator helps traders identify the strength and direction of market trends by analyzing the "inertia effect" of price action. It aims to capture the tendency of asset returns to persist in their current direction, allowing for effective trend-following strategies.
Usage
The indicator is visualized as a histogram on a separate pane, where the color and movement of the columns indicate market momentum:
- Bullish Momentum: Represented by green columns. A transition to green or an increasing green histogram suggests a strong upward trend, often used as a signal to initiate long positions.
- Bearish Momentum: Represented by red columns. When the histogram turns red or shows declining values, it indicates weakening momentum or a potential downtrend, signaling a time to close longs or consider short positions.
- Trend Reversals: The crossover or crossunder of the momentum signals (the first appearance of a color change) serves as the primary entry or exit point.
Details
The L2 Bull-Bear Momentum tool is based on the concepts of momentum effects proposed by Jegadeesh and Titman (1993). It calculates momentum by comparing short-term and long-term Exponential Moving Averages (EMAs) across various lookback periods (ranging from 2 to 150 bars).
The script incorporates complex mathematical transformations, including:
- Price Deviation: Analyzing the current price relative to its 100-bar range.
- Non-linear Scaling: Squaring and cubing momentum values to emphasize significant price movements over minor noise.
- Volatility Weighting: Using price products (geometric means of OHLC) and standard deviation factors to smooth the output and filter out low-volatility periods.
Settings
- Scaling Factor: Adjusts the overall sensitivity and magnitude of the momentum calculations. Increasing this value will make the histogram peaks more pronounced, while decreasing it will dampen the output.
FAQ
How do I access L2 Bull-Bear Momentum?
You can get access on the LuxAlgo Library for charting platforms like TradingView, MetaTrader (MT4/MT5), and NinjaTrader for free.
What is the best timeframe for this indicator?
While it can be used on any timeframe, it is particularly effective on higher timeframes (like 1H, 4H, or Daily) where momentum trends are more established and less prone to market noise.
Can I use this for mean reversion?
This tool is primarily designed for trend-following. While a peak in momentum might suggest an overextended market, its main strength lies in identifying when a trend has enough "inertia" to continue in its current direction.
