Three Inside Trading System for MetaTrader 5
Three Inside Trading System is a price action indicator for MT5 designed to detect 3-candle harami reversal patterns where a large mother candle is followed by a smaller inside candle and then a confirmation candle that validates the direction change.
A detailed user guide is available on the author’s MQL5 Blog.
Additional updates are available through the author’s MQL5 Channel.
Depending on the current support policy, buyers may receive additional access to selected companion tools developed by the author.
Overview
Three Inside Trading System detects both Three Inside Up and Three Inside Down formations using a large directional mother candle, a smaller inside candle contained within the mother body, and a third candle that confirms the reversal.
This pattern can be used to identify a pause in momentum followed by a confirmed directional breakout.
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 three-bar pattern through several structural conditions.
These conditions can include:
Minimum body ratio on the mother candle
Minimum range of the mother candle relative to ATR
Full containment of the inside candle body within the mother body
Maximum inside candle size relative to the mother candle body
Minimum body ratio on the confirmation candle
Confirmation close beyond the mother candle open
The indicator can detect both bullish and bearish harami reversal 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:
Mother body strength
Containment tightness
Confirmation strength
Breakout depth
Signals below the selected minimum threshold can be filtered out automatically.
Entry and trade planning
For confirmed setups, the indicator can project breakout levels above the pattern high for buy setups or below the pattern low for sell setups, with an 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 pattern-based placement, 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 Quality Filter, Extreme Zone Filter, Direction Filter, Stop Hunt Filter, Signal Zone Filter, Spacing 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 H4 and D1 because Three Inside patterns tend to be more meaningful on higher timeframes where harami reversals carry more weight.
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.
