RoGr75 - EMA Cross Signal with Buffer and Variable Distance

**Overview**:
This script is designed to identify potential buy and sell signals based on the crossover of two Exponential Moving Averages (EMAs) – a short-term EMA (default: 8 periods) and a long-term EMA (default: 50 periods). To reduce noise and false signals, the script incorporates a customizable buffer percentage, ensuring that signals are only generated when the short-term EMA moves significantly above or below the long-term EMA. Additionally, the script allows users to adjust the distance of the signals from the candles using the Average True Range (ATR) for better visualization.

Improvements: Added Buffer Percentage for reduced noise in Signals

### **Key Features**:
1. **EMA Crossover Signals**:
Buy Signal: Generated when the short-term EMA crosses above the long-term EMA.
Sell Signal: Generated when the short-term EMA crosses below the long-term EMA.

2. **Buffer Percentage**:
A user-defined buffer percentage ensures that signals are only triggered when the short-term EMA moves a specified percentage above or below the long-term EMA, reducing false signals.

3. **Customizable Signal Distance**:
Signals are plotted at a user-defined distance from the candles, calculated using the ATR (Average True Range) for dynamic positioning.

4. **Visual Enhancements**:
Buy and sell signals are displayed as labels above or below the candles, with optional background highlighting for better visibility.

5. **Flexible Inputs**:
Users can customize the lengths of the short-term and long-term EMAs, the ATR period, the signal distance multiplier, and the buffer percentage.

6. **Alerts**:
Built-in alert conditions allow users to receive real-time notifications for buy and sell signals.

### **Input Parameters**:
**Short EMA Length**: Period for the short-term EMA (default: 8).
**Long EMA Length**: Period for the long-term EMA (default: 50).
**Signal Distance**: Multiplier for ATR to determine the distance of signals from the candles (default: 2.0).
**ATR Length**: Period for the ATR calculation (default: 14).
**Buffer Percentage**: Percentage buffer for reversal signals to reduce noise (default: 1.0%).

### **Ideal For**:
Traders who use EMA crossovers as part of their strategy.
Those looking to reduce false signals with a buffer mechanism.
Users who prefer dynamic signal positioning based on market volatility (ATR).

### **Notes**:
The buffer percentage ensures that signals are only generated when the price moves significantly, making it suitable for trend-following strategies.
The script is highly customizable, allowing traders to adapt it to different timeframes and instruments.
