Custom Trend Indicator

前天

**Custom Trend Indicator**
This indicator identifies bullish and bearish trends using two simple moving averages (SMAs) of customizable lengths. The fast-moving average reacts more quickly to price changes, while the slow-moving average provides a smoother view of the trend. Key features include:

1. **Trend Detection:**
- A bullish trend is identified when the fast-moving average crosses above the slow-moving average.
- A bearish trend is identified when the fast-moving average crosses below the slow-moving average.

2. **Visual Aids:**
- Moving averages are plotted on the chart for clear trend visualization.
- Background colors (green for bullish, red for bearish) highlight the active trend.
- Labels are added at crossover points to mark significant trend changes.

This tool is helpful for traders looking to quickly identify and act on market trends based on simple moving average crossovers.
