L3 Breakout Indicator
Mar 27, 2025

The L3 Breakout Indicator tool identifies market entry and exit zones by analyzing price momentum relative to dynamic thresholds to highlight potential trend reversals and continuations.
Usage
The L3 Breakout Indicator provides a visual representation of price momentum through two primary lines: the Price Momentum Ratio and a Filtered Signal. Traders can interpret the market state based on how these plots interact with predefined boundary levels.
- Buy Signals: A potential buying opportunity is identified when the Price Momentum Ratio crosses above the Lower Threshold (default: 0.5). This is highlighted with a lime background and a "BUY" label.
- Sell Signals: A potential selling opportunity occurs when the momentum ratio crosses below the Upper Threshold (default: 2.9). This is highlighted with a red background and a "SELL" label.
- Trend Continuation: The Middle Boundary (fixed at 2.0) acts as a pivot. Persistent movement above or below this line indicates the strength of the current trend.
- Momentum Convergence: The area between the smoothed momentum ratio and the filtered signal is filled with a gradient, representing the convergence or divergence of price action.
Details
The script calculates momentum by comparing the current closing price to its 100-period low and 250-period high. This ratio is then smoothed using a 4-period Exponential Moving Average (EMA) to reduce market noise.
A unique aspect of the implementation is the "Filtered Signal Value," which uses a custom function to find the first non-NaN value within a short lookback. This creates a secondary signal line that allows for the visualization of momentum shifts through line crossovers and shaded fill areas. Because the script relies on historical extremes (100 and 250 periods), it provides a macro perspective on where current price sits within a long-term range.
Settings
- Lower Threshold: Sets the level for potential buy zone detection. Lowering this value makes the indicator more conservative for long entries.
- Upper Threshold: Sets the level for potential sell zone detection. Increasing this value requires higher momentum peaks before triggering a sell signal.
