ZAB Supply Demand MTF

ZAB Supply Demand MTF automatically detects institutional supply and demand zones across up to 9 timeframes and draws them directly on your chart. Based on Sam Seiden's methodology, this indicator identifies the exact zones where banks and institutions placed their orders. Why This Indicator? Unlike basic support/resistance tools, ZAB Supply Demand MTF classifies every zone by its formation pattern and merges overlapping zones from different timeframes into high-probability confluence areas. Key Features

• 4 Zone Pattern Types - Rally-Base-Rally (RBR), Drop-Base-Rally (DBR), Drop-Base-Drop (DBD), Rally-Base-Drop (RBD). Know exactly whether a zone is continuation or reversal.
• Multi-Timeframe Scanning - Scan M1 to MN simultaneously. Higher timeframe zones appear thicker and more opaque for instant visual hierarchy.
• 4 Overlap Handling Modes - Show All, HTF Priority, Confluence Highlight, or Smart Merge. Control exactly how overlapping zones from different timeframes are displayed.
• Zone Strength Rating - Each zone is rated Weak/Normal/Strong based on departure ratio, base candle count, and pattern type.
• Fresh Zone Tracking - Untested zones are highlighted with distinct colors. Zones are automatically invalidated after configurable test count.
• Complete Alert System - Popup, sound, and push notification alerts when price enters a zone. Configurable cooldown to prevent spam.
• Clean Visual Design - Customizable colors for supply/demand, fresh/tested zones, and confluence borders. Adjustable opacity per timeframe rank.

Zone Detection Parameters

• ATR Period - Controls the volatility measurement window (default: 14)
• Impulse Threshold - ATR multiplier for identifying strong departure candles (default: 1.5x)
• Base Candle Max Size - Maximum candle size for base detection (default: 0.5x ATR)
• Max/Min Base Candles - Control base width from 1 to 6 candles
• Lookback Bars - How far back to scan for zones (default: 500)

Multi-Timeframe Settings

• Enable/disable each timeframe individually: M1, M5, M15, M30, H1, H4, D1, W1, MN
• Always Show Current TF option ensures your chart timeframe zones are always visible
• Overlap threshold controls when zones from different TFs are considered overlapping (0.0-1.0)

Zone Filtering

• Max Tests Before Invalidation - Remove zones after N touches (default: 2)
• Show Fresh Zones Only - Hide all tested zones for a cleaner chart
• Toggle Reversal (RBD/DBR) and Continuation (RBR/DBD) zones independently

Alert Settings

• Popup, Sound, and Push Notification alerts
• Alert cooldown in minutes to prevent repeated alerts
• Option to alert only on fresh (untested) zones

Visual Customization

• Separate colors for Demand, Supply, Fresh Demand, Fresh Supply zones
• Confluence border color (Gold by default)
• Zone opacity control (0-100%)
• Toggle labels and strength ratings on/off

How It Works

1. The indicator scans each enabled timeframe for impulse candles (large body relative to ATR)
2. It looks for base candles (small body) immediately before the impulse
3. The pre-base candle determines the pattern: reversal (DBR/RBD) or continuation (RBR/DBD)
4. Zone boundaries are set from the base candle high/low
5. Overlapping zones across timeframes are handled according to your chosen mode
6. Zones are tracked in real-time: tested zones change color, broken zones are removed

Best Practices

• Use H1+H4+D1 combination for swing trading
• Use M15+M30+H1 for intraday setups
• Set Overlap Mode to "Merge" for the cleanest chart with strongest zones highlighted
• Focus on Fresh + Strong zones for highest probability entries
