Three Line Strike Trading System

Line Strike Trading System for MetaTrader 5

Line Strike Trading System is a price action indicator for MT5 designed to detect 4-bar Three Line Strike patterns and generate structured trade setups after confirmation.

Overview

Line Strike Trading System detects four-candle reversal structures where three consecutive trend candles build a directional staircase and a fourth strike candle reverses the entire formation.

This pattern can be used to identify strong rejection after an extended short-term sequence in one direction.

All calculations are based on completed bars only.

Detection is non-repainting. Signal values do not change after the bar is closed.

The indicator can draw Entry, Stop Loss, and Take Profit levels directly on the chart and track signal progress after detection.

Detection Logic

The detection model evaluates each completed four-bar pattern through several structural conditions.

These conditions can include:

Three consecutive trend candles moving in the same direction

Minimum body size relative to candle range

Minimum range relative to ATR

Stair-step progression across the first three candles

A final strike candle that reverses and engulfs the prior body structure

The indicator can detect both bullish and bearish Three Line Strike structures.

Patterns that do not meet the selected structural requirements are ignored.

Quality Evaluation

Each valid pattern can be evaluated through a multi-factor quality model.

The scoring process can include measurements such as:

Stair-step consistency

Engulf strength

Strike body ratio

Trend context

Signals below the selected minimum threshold can be filtered out automatically.

Entry and trade planning

For confirmed setups, the indicator can project entry levels at the strike candle close or with an optional ATR buffer.

For each valid setup, the indicator can display:

Entry level

Stop Loss level

Up to four Take Profit levels

Risk and reward zones on the chart

Stop Loss can be calculated using Donchian Channel logic or ATR-based logic.

An optional trailing stop based on Donchian logic is also available for users who want dynamic trade management after entry.

Filters and tools

Optional filters are available to reduce unnecessary signals.

These include Direction Filter, Extreme Zone Filter, Stop Hunt Filter, Signal Zone Filter, and Opposite Signal Filter.

The built-in scanner can monitor up to 150 symbols across 8 timeframes from a single chart.

The indicator also includes BOS and CHOCH labels, a signal dashboard, alert options, chart themes, and output buffers for Expert Advisor integration.

Recommended use

Recommended timeframes are H1, H4, and D1 because Three Line Strike patterns generally become clearer when trend structure is more visible.

The indicator can be applied to Forex pairs, XAUUSD, indices, and crypto symbols, depending on broker data quality and symbol characteristics.

Loading sufficient chart history is recommended for more stable structure analysis.
