EMA Crossover Signal+Email_002
Download script
This script is designed as a visual and notification tool for traders who use Exponential Moving Averages (EMA) to determine market trends. Its primary purpose is to identify the exact moment two different moving averages cross paths, which often signals a change in momentum or a potential entry point for a trade.
How the Logic Works
The script monitors two distinct timeframes of price movement: a "Faster" EMA and a "Slower" EMA. By comparing these two lines, the tool looks for specific crossover events:
- Bullish Signal (Trend Up): When the Faster EMA moves from below the Slower EMA to above it, the script identifies this as an upward trend shift.
- Bearish Signal (Trend Down): When the Faster EMA moves from above the Slower EMA to below it, the script identifies this as a downward trend shift.
Key Features and Visual Aids
To make these signals easy to interpret, the script performs several automated actions:
- Visual Markers: Instead of forcing you to squint at tiny lines on a crowded chart, the script places distinct arrows directly on the price candles. These markers appear precisely where the crossover occurs, helping you identify historical trends even when you are zoomed out or looking at different timeframes.
- Dynamic Positioning: The tool automatically calculates the "Range" of the price action around the crossover point. It then places the arrows slightly above or below the candle (depending on the direction) so that they remain clearly visible without overlapping the price bars.
- Real-Time Alerts: The script doesn't just show you what happened in the past; it can notify you of what is happening right now. If a crossover occurs on the most recent completed bar, the tool can trigger:
- Audio Alerts: A sound notification within your trading platform.
- Email Notifications: An automated email sent to your registered address providing the symbol name and the timeframe of the move.
- Smart Filtering: The system includes a "tag" logic that prevents it from sending multiple alerts for the same signal. It ensures you only receive one notification per trend shift, keeping your inbox and workspace organized.
Customization
Users have the flexibility to adjust the settings to match their specific trading style. You can define the length of both the Faster and Slower EMAs, as well as toggle the sound and email notifications on or off depending on your preference.

| Allows you to enter two ema 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. (emas are initially set at 5 and 6) |
