Three Line Strike Trading System

Detects 4-bar Three Line Strike patterns where three consecutive trend candles form an ascending or descending staircase, followed by a single engulfing strike candle that reverses the entire structure. Covers both Bullish Three Line Strike (3 bull ascending + bear strike) and Bearish Three Line Strike (3 bear descending + bull strike). Each signal is scored by 4 weighted quality factors: stair-step consistency, engulf strength, strike body ratio, and trend context.

This indicator identifies Three Line Strike formations on any symbol and timeframe, draws automated Entry/SL/TP trading levels, and tracks signal performance in real-time. Includes a multi-timeframe scanner monitoring up to 150 symbols across 8 timeframes simultaneously.

Included Tools

Each Line Strike Trading System purchase includes access to the following companion tools at no additional cost:

1. Smart Trend Consensus MT5 — Multi-timeframe trend agreement indicator. Displays trend direction across up to 7 timeframes on a single dashboard. Helps filter Three Line Strike signals by confirming trend alignment before entry. https://www.mql5.com/en/market/product/160553

2. Price Volume Distribution MT5 — Volume profile and price distribution analysis. Identifies high-volume price zones where institutional orders cluster. Useful for confirming support/resistance confluence with strike pattern locations. https://www.mql5.com/en/market/product/160452

3. Line Strike Trading System EA — Automated signal execution based on indicator output buffers. Reads Entry/SL/TP levels from the indicator and places pending orders automatically. Configurable lot sizing, risk per trade, and session filters. (Delivered via MQL5 private message after purchase confirmation.)

Contact the author through MQL5 messaging after purchase to receive access to the companion tools.

How Three Line Strike Detection Works

The indicator scans for a 4-candle structure on each completed bar:

1. Three Trend Candles — Three consecutive candles moving in the same direction with progressive closes (ascending for bullish, descending for bearish). Each must have a long body (default 60% of range) and sufficient range (default 0.50x ATR). Doji candles are filtered out.

2. Stair-Step Validation — Each subsequent candle must open within the body of the prior candle and close progressively further in the trend direction. Two modes available: Close progression (default) or Body High/Low progression.

3. Strike Candle — The fourth candle must be in the opposite direction and completely engulf the bodies of all three trend candles. For bullish patterns, the bear strike opens above candle 3's close and closes at or below candle 1's open. For bearish patterns, the reverse applies.

4. Entry — Placed at the strike candle close price with an optional ATR buffer (default 0.0x for immediate entry at close).

5. Stop Loss — Placed at the strike candle low (bullish) or high (bearish) with an ATR buffer (default 0.10x). Alternative methods: Donchian Channel or ATR multiplier.

4-Factor Quality Scoring evaluates:

• Stair-Step Consistency: how similar the 3 trend candle bodies are in size (weight 25%, ideal low deviation)
• Engulf Strength: strike body vs the 3-candle body span (weight 25%, ideal 1.00-2.00x)
• Strike Body Ratio: strike body significance within its range (weight 25%, ideal 0.70-1.00)
• Trend Context: directional alignment with SMA trend filter (weight 25%, ideal 0.50-1.00)

Pattern-Specific Settings:

• Long Body Ratio (body/range threshold for trend candles)
• Min Range/ATR (significance filter for trend candles)
• Doji Body Pct (filter doji candles)
• Strict Mode (require gap + new H/L on strike)
• Stair-Step Mode (Close progression or Body progression)
• Trade Direction (Continuation, Reversal, or Both)
• Entry Buffer (ATR multiple)
• SL Buffer (ATR multiple)
• Trend SMA Period (0=disable)
• Min Quality threshold

Automated Trading Levels

Every detected pattern automatically draws Entry, Stop Loss, and up to 4 Take Profit levels (TP1-TP4) based on configurable Risk:Reward ratios. Price labels display pip distance and R:R ratio for each level.

Stop Loss methods:

• Donchian Channel (structure-based, adapts to volatility)
• ATR Multiplier (fixed distance based on Average True Range)

Default R:R targets: TP1=1.0R, TP2=2.0R, TP3=3.0R, TP4=4.0R (all customizable, set to 0 to disable any level).

Live Signal Tracking

The indicator tracks each signal from detection through completion:

• Pending: waiting for entry price to be hit
• Active: entry hit, tracking toward TP or SL
• Finished: TP or SL reached

A dotted tracking path shows the actual price movement after each signal. Profit/loss labels appear at hit points. Zone fill rectangles visualize risk and reward areas on the chart.

Donchian Channel Trailing Stop

An optional trailing stop system that automatically adjusts the stop loss as price moves favorably:

• Uses the Donchian Channel (lowest low / highest high over N bars)
• Activates after price reaches a configurable R:R threshold
• Locks at breakeven when TP1 is hit
• Visual color changes: orange (trailing buy), yellow (trailing sell), green (locked at breakeven)

Multi-Timeframe Scanner (150 Symbols x 8 Timeframes)

Monitor patterns across the entire market from a single chart:

• Scans up to 150 symbols from your Market Watch
• Checks 8 timeframes: M1, M5, M15, M30, H1, H4, D1, W1
• Live dashboard panel shows detected signals with quality scores
• Configurable batch scanning to control CPU usage
• Independent alert system for scanner-detected signals

Scanner can operate in two modes:

• Current Symbol MTF: scans only the chart symbol across all timeframes
• Full Market Scan: scans all Market Watch symbols across selected timeframes

Market Structure Analysis (BOS / CHOCH)

Built-in Break of Structure and Change of Character detection:

• Identifies swing highs and lows using fractal analysis
• Labels swing sequences: HH (Higher High), HL (Higher Low), LH (Lower High), LL (Lower Low)
• Detects BOS (trend continuation) and CHOCH (trend reversal) events
• Configurable timeframe and sensitivity
• Visual lines and labels on chart

Multi-Layer Signal Filtering

Five independent filters to reduce noise and increase signal quality:

1. Direction Filter — Only allow signals aligned with the current trend direction (auto-detects from market structure, or set manually)
2. Extreme Zone Filter — Block signals near overbought/oversold zones using Donchian Channel position thresholds
3. Stop Hunt Filter — Validate that signals originate from genuine liquidity sweeps of prior swing levels
4. Signal Zone Filter — Require signals to form near meaningful market structure events (BOS, CHOCH, swing levels)
5. Opposite Signal Filter — Prevent conflicting buy/sell signals from appearing simultaneously

Each filter can be enabled/disabled independently.

4-Channel Alert System

Never miss a signal with multi-channel notifications:

• Desktop Popup Alert (MT5 Alert dialog)
• Sound Alert (customizable sound file)
• Mobile Push Notification (MT5 mobile app)
• Configurable for Entry hits, TP hits, and SL hits separately

Anti-spam: once-per-signal deduplication with configurable cooldown period.

Signal Statistics Dashboard

A draggable panel displaying real-time performance metrics:

• Total signals detected
• Win/Loss count and Win Rate percentage
• Active vs completed signal counts
• Customizable position, font size, and row height

Professional Chart Themes

Built-in color schemes for comfortable chart reading:

• Dark Muted (default) — reduced eye strain
• Dark — high contrast
• Light — bright background
• Custom — full color control for every chart element

Original chart colors automatically restored when indicator is removed.

EA Signal Buffers

Indicator outputs are available as data buffers for Expert Advisors:

• Buffer 0: Signal direction (1=Buy, -1=Sell)
• Buffer 1: Entry price
• Buffer 2: Stop Loss price
• Buffer 3-6: TP1-TP4 prices
• Buffer 7: Quality score

Connect your EA to read these buffers for automated trade execution.

Recommended Settings

• Timeframes: H1, H4, D1 (three-line strike patterns require strong trend context visible on higher timeframes)
• Symbols: Works on all Forex pairs, Gold (XAUUSD), Indices, and Crypto pairs
• Account type: Any (demo or live)

You set SL at 1990.00, and it stays there forever — even if price has risen to 2030.00.Trailing Stop Loss (TSL) is different. It automatically moves in your favor when price advances. As price moves up, TSL moves up with it. When price stalls or reverses, TSL holds the best position it reached.
