Outside Bar Trading System

Outside Bar Trading System is a price action indicator for MT5 designed to detect two-bar range expansion patterns and display structured breakout levels on the chart.

Overview

Outside Bar Trading System detects a two-bar pattern in which the second candle fully exceeds the range of the first candle.

This structure can be used to identify range expansion and possible continuation opportunities when price resumes movement after a short pause or compression.

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 is based on two completed candles:

• Bar 1 defines the reference range

• Bar 2 extends above the previous high and below the previous low

• Additional filters can be applied to evaluate range expansion, candle body quality, and directional context

The indicator can also evaluate short-term trend context before accepting the setup.

Each candidate pattern can be checked through structural conditions such as:

• Range expansion relative to ATR

• Expansion of Bar 2 relative to Bar 1

• Body size

• Body ratio

• Close position within the candle range

• Trend alignment

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

Multiple detection modes are available, including Standard Mode, Strict Mode, and Custom Mode.

Entry and trade planning

For confirmed setups, the indicator can project breakout levels using pending-style entry logic above or below the outside bar range.

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

Take Profit levels can be displayed as 0.5R, 1.0R, 1.5R, and 2.0R.

Stop Loss can be calculated using a pattern-based method, ATR-based logic, or Donchian Channel reference.

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:

• Quality Filter

• Extreme Zone Filter

• Direction Filter

• Stoploss Hunt Filter

• Signal Zone Filter

• Spacing Filter

• Opposite Signal Filter

The built-in scanner can monitor multiple symbols and timeframes from a single chart.

The indicator also includes BOS and CHOCH labels, a signal dashboard, alert options, chart themes, statistics tracking, and output buffers for Expert Advisor integration through iCustom().

Recommended use

Recommended timeframes are H1 and H4 for clearer structure, while lower timeframes can be used with stricter filtering settings.

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.
