ADX Crossing
Download script
This tool is designed to identify specific shifts in market momentum by monitoring the relationship between two opposing trend indicators. Rather than tracking the overall strength of a movement, it focuses on the "tug-of-war" between bullish (upward) and bearish (downward) forces to pinpoint moments where the lead changes.
Core Logic Overview
The script operates by analyzing two specific components: the Plus Directional Index (+DI), which represents upward pressure, and the Minus Directional Index (-DI), which represents downward pressure. The logic follows a simple "cross-over" principle:
- Bearish Signal (Red): The tool looks for a moment where the bullish force was previously stronger than the bearish force but has now dropped below it. When this transition occurs, the script identifies a potential shift toward downward momentum.
- Bullish Signal (Lime): Conversely, the tool watches for instances where the bearish force was previously dominant but has been overtaken by the bullish force. This identifies a potential shift toward upward momentum.
How It Works on Your Chart
Instead of creating a continuous line that might clutter your view, the script acts as an alert system using visual markers:
- Momentum Tracking: The tool constantly scans back through a specific number of historical bars (user-defined) to ensure it captures every relevant transition.
- Signal Detection: It compares the values from the current candle against the previous candle to see if a "cross" has occurred.
- Visual Marking:
- When a downward cross is detected, an arrow appears slightly below the candle's low price.
- When an upward cross is detected, an arrow appears slightly above the candle's high price.
Key Customizations
The behavior of the script can be adjusted through two primary settings:
- ADXbars: Determines the sensitivity of the trend calculation. A higher number will smooth out the data (fewer signals, but potentially more reliable), while a lower number will make the tool more responsive to quick price flickers.
- CountBars: Controls how much historical data the script reviews on your screen at one time.
In summary, this script serves as a visual "crossing" notifier, highlighting the exact moments when market sentiment flips from one direction to another based on directional momentum.
