Download script
This tool is designed as a visual momentum indicator for trading platforms. It functions by analyzing recent price movements to determine the current strength of a market trend, helping traders distinguish between active trends and periods of consolidation.
Core Logic and Methodology
The script operates by examining a specific "look-back" window of historical price data—defined by a user-adjustable period (set to 21 bars by default). Instead of looking at just the most recent price, it compares the current closing price against a series of previous prices within that window.
How the calculation works:
- Comparative Analysis: The logic loops through the previous 10 price points relative to the current bar.
- Trend Scoring: For every price point in that sequence, the tool performs a simple "higher or lower" check:
- If the current price is higher than a previous price in the sequence, it assigns a positive value (+1).
- If the current price is lower than a previous price, it assigns a negative value (-1).
- Net Momentum Score: The script sums these values together to create a final "net score" for that specific point in time.
Visual Representation
The result of this calculation is plotted as a line on a separate window below your main chart.
- Positive Values: When the line moves above zero, it indicates that the current price is consistently higher than the recent historical average, suggesting upward momentum.
- Negative Values: When the line drops below zero, it indicates that the current price is lower than the recent historical average, suggesting downward momentum.
- Neutrality: When the score sits near zero, it suggests a lack of clear direction, where the price is fluctuating without a dominant trend.
By following this line, traders can visually identify when a trend is gaining strength (the line moving further away from zero) or losing steam (the line moving back toward zero), providing a clearer picture of market sentiment than price action alone.
