# Distribution & Accumulation Days Indicator

## Overview
This powerful institutional activity tracker identifies **Distribution Days** (selling pressure) and **Accumulation Days** (buying pressure) based on the proven methodology used by Investor's Business Daily (IBD). Perfect for detecting when "smart money" institutions are actively buying or selling, helping you align your trades with institutional flow.

## What It Does
- **Distribution Days**: Identifies days when price drops significantly on higher volume (institutional selling)
- **Accumulation Days**: Identifies days when price rises significantly on higher volume (institutional buying)
- **Real-time Counting**: Tracks the number of each type over your specified lookback period
- **Net Analysis**: Shows whether buying or selling pressure is dominant

## Key Features

### 🎯 **Customizable Threshold**
- Set your own price change percentage (default 0.2%) to filter out minor moves
- Focus only on significant institutional activity

### 📊 **Moving Average Filter**
- Optional MA filter to eliminate noise during strong downtrends
- Choose from SMA, WMA, or EMA
- Only counts signals when price is above the moving average

### 📈 **Visual Markers**
- **Red 'D'** markers above bars = Distribution (selling pressure)
- **Green 'A'** markers below bars = Accumulation (buying pressure)
- Numbers show current count within your lookback period

### 📋 **Information Dashboard**
Real-time table displays:
- Total Distribution Days in period
- Total Accumulation Days in period
- Net difference (positive = more buying, negative = more selling)

## How to Use

### Market Analysis
- **4-5 Distribution Days** in 25 sessions = Potential market weakness
- **Multiple Accumulation Days** after decline = Potential bottom formation
- **Net positive** = Institutional buying dominance
- **Net negative** = Institutional selling dominance

### Trade Setup
- Look for accumulation clusters near support levels for long entries
- Watch for distribution clusters near resistance for potential short setups
- Use in conjunction with your existing technical analysis

## Settings

| Parameter | Description | Default |
|-----------|-------------|---------|
| Days Back | Lookback period for counting | 25 |
| Price Change Threshold | Minimum % move required | 0.2% |
| Moving Average Filter | Enable/disable MA filter | Off |
| MA Type | SMA, WMA, or EMA | EMA |
| MA Length | Moving average period | 50 |

## Best Practices
- Use on **daily timeframe only** (automatically restricts to daily)
- Works best on major indices (SPY, QQQ, IWM) and liquid stocks
- Combine with support/resistance levels for better entries
- Monitor both individual counts and net difference for complete picture

## Important Notes
- Based on proven IBD methodology used by professional traders
- Requires significant volume confirmation - price moves without volume are ignored
- Most effective when used as part of a complete trading system
- Works only on daily charts (designed for institutional timeframe analysis)
