Zero Lag Trend Signals (MTF) + Sideways Filter

This script is a custom indicator for TradingView that combines two major components: the **Zero Lag Trend** (with MTF support) and a **Sideways Market Filter**. Let me break down the key features and functions of the script:

### Key Components:
1. **Zero Lag Trend Signals**:
- **Zero Lag Trend (ZLEMA)**: A smoothed moving average designed to minimize lag and give faster responses to price movements. This is used to determine the trend.
- **Trend Bands**: Upper and lower bands are derived from the ZLEMA value and adjusted by volatility (calculated using Average True Range or ATR).
- **Trend Direction**: The trend direction is determined by whether the price crosses over the upper or lower band of the ZLEMA, indicating bullish or bearish trends.

2. **Sideways Market Filter**:
- **RSI (Relative Strength Index)**: Measures the speed and change of price movements. It's used here to identify neutral or sideways market conditions when RSI is between 40 and 60.
- **ADX (Average Directional Index)**: Measures the strength of a trend. The script considers a sideways market when ADX is less than 25 and both DI+ and DI- are low.
- **Sideways Market Condition**: A sideways market is defined when the RSI is in the range of 40 to 60 and the ADX is below 25, indicating weak trends.

### Main Features:
1. **Sideways Market Indicators**:
- **Sideways Circles**: When the market is identified as "sideways" based on RSI and ADX conditions, a small circle is plotted either above or below the bars on the chart. The user can adjust the color of the circles via the indicator settings.
- **Sideways Market Filter**: This filter helps to determine when to stay out of trend-based signals, and its detection is visually marked by the circles.

2. **Zero Lag Trend (ZLEMA) Plot**:
- **ZLEMA**: The Zero Lag Exponential Moving Average is plotted as a baseline, and the direction of the trend is indicated by color changes. Green is used for bullish trends, and red is used for bearish trends.
- **Trend Bands**: The script calculates upper and lower bands around the ZLEMA using volatility, and these bands help identify areas of potential trend reversal.

3. **Trend Plotting**:
- **Trend Arrows**: When the trend crosses from bullish to bearish or vice versa, the script plots arrows ("▲" for bullish and "▼" for bearish) above or below the bars on the chart to indicate the signal.
- **Trend Entry Points**: Small arrows are plotted when an entry point is detected for a long (bullish) or short (bearish) position.

4. **Multi-Timeframe (MTF) Trend Signals**:
- The script includes multi-timeframe (MTF) analysis by checking the trend on different timeframes (5m, 15m, 60m, 240m, and 1D).
- A **data table** is displayed on the chart showing the trend status for each of these timeframes (Bullish or Bearish), helping the trader visualize the trend across multiple timeframes.

5. **Alerts**:
- **Alert Conditions**: Alerts are triggered when specific conditions are met, such as:
- Bullish or bearish trend crossover.
- Zero Lag Trend crossing the price.
- Trend change signals on any of the timeframes.
- Alerts for bullish and bearish entry signals based on the trend.

### Inputs for Customization:
- **Zero Lag Trend Parameters**: Length, multiplier for the band, and timeframes for MTF analysis (t1, t2, t3, t4, t5).
- **Color Customization**: Colors for bullish and bearish trends, as well as the fill colors for the bands and the sideways market circles.
- **Sideways Market Filter Parameters**: RSI length, ADX length, and options for showing sideways market circles.
- **Circle Customization**: You can adjust the size, color, and location (above or below bars) of the sideways market circles.

### Summary:
This indicator is a sophisticated tool that combines the **Zero Lag Trend** and **Sideways Market Filter** to help traders:
- Identify strong trends (bullish or bearish) using the ZLEMA and volatility bands.
- Stay out of choppy or sideways markets using the RSI and ADX filter.
- Make trading decisions based on trend confirmation across multiple timeframes (MTF).
- Customize the visual appearance, including color schemes, circle size, and alert conditions.

This script is perfect for traders who want to focus on trading trends while avoiding market conditions that are not conducive to strong directional moves.
