Arrow Signal System

Indicator Overview

The MV Arrow Signal System is a comprehensive multi-indicator trading system for MetaTrader 4 that identifies potential buy and sell signals based on swing point detection combined with multiple technical confirmation filters.

Core Concept

The system scans price charts to identify swing highs and swing lows, then applies a scoring system based on multiple technical indicators to validate these potential reversal points. Only high-probability signals that meet strict criteria are displayed as arrows on the chart.

Technical Components

1. Swing Detection Engine

• Swing Low Detection: Identifies bars that are lower than a specified number of bars to both left and right

• Swing High Detection: Identifies bars that are higher than a specified number of bars to both left and right

• Configurable Lookback Periods: Adjustable left/right bar counts for swing sensitivity

2. Signal Confirmation System (Scoring)

Each swing point is evaluated based on 3 primary conditions:

For BUY Signals:

1. EMA Crossover: Fast EMA (8) is greater than or equal to Slow EMA (21) = +1 point

2. RSI Condition: RSI is less than 40 = +1 point

3. Bollinger Band Position: Price is less than or equal to Middle Bollinger Band = +1 point

For SELL Signals:

1. EMA Crossover: Fast EMA (8) is less than or equal to Slow EMA (21) = +1 point

2. RSI Condition: RSI is greater than 60 = +1 point

3. Bollinger Band Position: Price is greater than or equal to Middle Bollinger Band = +1 point

3. Advanced Filters

Trend Filter (Optional):

• Uses a 50-period EMA to determine overall trend direction

• BUY signals require price greater than trend EMA (uptrend confirmation)

• SELL signals require price less than trend EMA (downtrend confirmation)

Volume Confirmation (Optional):

• Compares current bar volume to 20-bar average

• Requires volume greater than or equal to 120% of average (configurable)

• Filters out low-volume, unreliable signals

Swing Size Filter:

• Uses Average True Range (ATR) to measure swing significance

• Minimum swing size: 0.3 times ATR (configurable)

• Filters out minor, insignificant price movements

Signal Spacing Control:

• Minimum 25 bars between signals of same type

• Prevents signal overcrowding and reduces false signals

Visual Features

Arrow Display:

• Green Up Arrows (Code 233): Buy signals

• Red Down Arrows (Code 234): Sell signals

• Configurable Colors and Widths

• Smart Positioning: Arrows placed above/below price bars for clear visibility

• Score Labels: Each arrow shows its confirmation score (B2, B3, S2, S3)

Information Display:

• Text labels showing signal strength

• Automatic cleanup of old signals

• Chart redrawing for optimal performance

Signal Logic

Buy Signal Generation:

1. A swing low is detected (bar is lower than N bars to left and right)

2. Swing size meets minimum ATR requirement

3. Volume is above average (if volume filter enabled)

4. Price is in uptrend relative to trend EMA (if trend filter enabled)

5. Score at least 2 out of 3 conditions (or 3/3 if RequireAllConditions is true)

6. Minimum bars have passed since last buy signal

Sell Signal Generation:

1. A swing high is detected (bar is higher than N bars to left and right)

2. Swing size meets minimum ATR requirement

3. Volume is above average (if volume filter enabled)

4. Price is in downtrend relative to trend EMA (if trend filter enabled)

5. Score at least 2 out of 3 conditions (or 3/3 if RequireAllConditions is true)

6. Minimum bars have passed since last sell signal
