SMMA-Crossover_Signal_v3
Download script
This script is designed as a visual aid for traders who use Moving Averages to determine market trends. Its primary purpose is to identify and highlight the exact moments when two different smoothed moving averages (SMMA) cross over each other, signaling a potential change in momentum.
How it Works
The tool monitors two distinct moving average lines on your chart: a "Faster" line and a "Slower" line. By default, these are set to periods of 9 and 18, respectively. Because moving averages can sometimes be difficult to read—especially when zoomed out or hidden behind the price bars—this script acts as a visual filter to pinpoint specific transition points.
Key Features and Logic
- Crossover Detection: The logic constantly scans the price history to see when the Faster SMMA moves from below the Slower SMMA to above it (a potential "Up" signal), or from above to below it (a potential "Down" signal).
- Visual Signaling: Instead of making you squint at the lines, the script automatically places specific symbols on your chart at the precise candle where these crossovers occur.
- An upward signal is plotted slightly below the low of the price candle.
- A downward signal is plotted slightly above the high of the price candle.
- Dynamic Positioning: To ensure the markers are easy to see and do not overlap with the candles, the script calculates the average range of recent price movements. It uses this data to offset the signals perfectly, placing them just far enough away from the bars to remain visible without cluttering the workspace.
- Chart Clarity: One of the main benefits of this tool is that it allows you to keep your chart clean. Since the script handles the "heavy lifting" of identifying the crossovers, you have the option to remove the actual moving average lines from your view, leaving only the clear visual signals behind.

//| Allows you to enter two smoothed sma periods and it will then |
//| show you at Which point they crossed over. It is more usful on |
//| the shorter periods that get obscured by the bars / candlesticks |
//| and when the zoom level is out. Also allows you then to remove |
//| the emas from the chart. (smas are initially set at 9 and 18) |
