Multitime ATR with ATR Heat Line

# Multi-Timeframe ATR Supertrend with ATH Finder

## Overview
This advanced Pine Script indicator combines multi-timeframe ATR-based Supertrend analysis with an All-Time High (ATH) tracking system. Designed for swing traders who need comprehensive trend analysis across multiple timeframes while monitoring key price levels.

## Key Features

### 1. Multi-Timeframe ATR Supertrend (1H, 4H, 1D)
- **1 Hour Supertrend** (Blue): Short-term trend identification
- **4 Hour Supertrend** (Purple): Medium-term trend confirmation
- **1 Day Supertrend** (Green/Red): Primary trend direction
- Each timeframe displays independent trend lines with customizable colors and visibility

### 2. Dual ATR Data System (1D Only)
- **Previous Day ATR** (lookahead_off): Used for main ATR lines - enables pre-market study and avoids intraday crossover issues
- **Current Day ATR** (lookahead_on): Used for Overheating Line calculation - provides real-time profit-taking signals

### 3. Overheating Line
- Dynamically calculated as: `1D ATR + (ATR Width × 1.3)`
- Orange line indicating potential overextension zones
- Uses current day real-time ATR for intraday decision-making
- Only displays during uptrends
- Customizable multiplier (default: 1.3)

### 4. ATH (All-Time High) Finder
- Automatically tracks and displays the all-time high with a horizontal line
- **Line Color**: Lime green (customizable)
- **Label System**:
- Green label when price is at ATH
- Red label when ATH is historical
- Toggle label visibility independently
- **Bug Fix**: Prevents vertical line display when ATH occurs on current bar
- Line extends to the right for easy visualization

### 5. Warning & Break Signals
Each timeframe provides two types of alerts:
- **Warning Signal** (⚠️): Price closes below uptrend line (potential reversal warning)
- **Break Signal** (⚡): Price closes above downtrend line (potential breakout)
- Smart timing intervals prevent signal spam:
- 1H: Checks every 4 hours (warning) / 1 hour (break)
- 4H/1D: Max 2 signals per day

### 6. Trend Change Indicators
- Small circles mark the exact bar where trend changes occur
- Color-coded for each timeframe
- Helps identify reversal points and trend strength

### 7. Master Control Switches
Efficiently manage all visual elements:
- **Master Highlighter**: Toggle all background fills on/off
- **Master Signals**: Toggle all warning/break signals
- **Master Up Trend**: Toggle all uptrend lines and circles
- **Master Down Trend**: Toggle all downtrend lines and circles

### 8. Fast Cut Lines (Optional)
- Additional support/resistance lines offset by a percentage from main ATR lines
- Useful for tighter stop-loss management
- Separate controls for up and down trends
- Default: OFF (customizable offset percentage)

### 9. Timeframe Visibility Control
- **Hide on Daily+**: Automatically hides indicators (except 1D ATR) on daily timeframes and above
- Reduces chart clutter on higher timeframes
- 1D ATR always visible regardless of chart timeframe

### 10. EMA Integration (Optional)
- Display 20/50/200 EMAs for confluence with ATR trends
- Toggle on/off independently

## Use Cases

### For Swing Traders
1. **Entry Timing**: Wait for multiple timeframe alignment (1H, 4H, 1D all in uptrend)
2. **Trend Confirmation**: Use trend change circles to identify momentum shifts
3. **Profit Taking**: Monitor Overheating Line for potential exit zones

### For Position Management
1. **Stop Loss Placement**: Use 1D ATR line or Fast Cut lines as dynamic stop levels
2. **Risk Assessment**: Distance between timeframe ATR lines indicates volatility
3. **Breakout Trading**: Break signals (⚡) identify potential breakout opportunities

### For Pre-Market Analysis
- 1D ATR uses previous day data, allowing traders to:
- Study support/resistance levels before market open
- Plan entry/exit strategies based on confirmed data
- Avoid false signals from incomplete daily candles

## Best Practices

1. **Multiple Timeframe Confirmation**: Don't trade against higher timeframe trends
2. **Overheating Awareness**: Consider profit-taking when price reaches orange line
3. **ATH Monitoring**: Exercise caution near all-time highs (increased volatility risk)
4. **Signal Filtering**: Use warning signals as alerts, not immediate action triggers
5. **Stop Loss Management**: Place stops below the most relevant ATR line for your timeframe
