Three Inside Trading System

Three Inside Trading System — Harami Reversal Pattern Detection

A large directional candle followed by a smaller inside candle whose body is fully contained within the mother body, then a third candle that confirms the reversal by closing beyond the mother's open — that is the Three Inside Up (bullish) and Three Inside Down (bearish) pattern. The inside bar creates a classic harami structure showing indecision, while the confirmation candle validates the direction change. This 3-bar formation signals a pause in momentum followed by a decisive breakout, not random price noise.

Three Inside Trading System detects both Three Inside Up (bullish harami reversal) and Three Inside Down (bearish harami reversal) formations on any symbol and timeframe. Each detected pattern receives automated Entry, Stop Loss, and up to 4 Take Profit levels (TP1-TP4) drawn directly on the chart. A built-in multi-timeframe scanner monitors up to 150 symbols across 8 timeframes simultaneously. MANUAL  | MY CHANNEL 

How Three Inside Pattern Detection Works

The indicator scans for a 3-candle harami reversal structure on each completed bar:

1. Mother Bar Validation — A large directional candle with body ratio ≥ 50% and range ≥ 0.5× ATR (strong initial trend momentum)
2. Inside Bar Containment — The second candle's body must be fully within the mother body (body-only containment, wicks can extend), creating a classic harami pause
3. Inside Bar Size Check — Inside body must be ≤ 60% of mother body (true containment, not just overlap)
4. Confirmation Breakout — Third candle must have body ratio ≥ 35% and close beyond the mother's open price (decisive reversal confirmation)

Three Inside Up (bullish): Mother bearish → Inside contained → Confirm closes above mother open. Three Inside Down (bearish): Mother bullish → Inside contained → Confirm closes below mother open.

Entry is placed above the pattern high (buy) or below the pattern low (sell) + ATR buffer. Stop Loss covers the entire 3-candle range or uses Donchian Channel.

4-Component Quality Scoring evaluates (equal-weight factors):

• Mother Body Strength: Mother body size / ATR (ideal 0.50-1.50× ATR)
• Containment Tightness: 1.0 - (inside_body / mother_body) (ideal 0.50-0.95, tighter = better)
• Confirmation Strength: Confirm body size / ATR (ideal 0.35-1.20× ATR)
• Breakout Depth: (confirm close beyond mother open) / mother_body (ideal 0.30-1.00)

Three Inside-Specific Settings:

• Mother candle: minimum body ratio (default 0.50), minimum range/ATR (default 0.50)
• Inside candle: maximum body vs mother body (default 0.60)
• Confirmation candle: minimum body ratio (default 0.35)
• Entry buffer (ATR multiple, default 0.05)
• SL buffer (ATR multiple, default 0.10)

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=0.5R, TP2=1.0R, TP3=1.5R, TP4=2.0R (fully 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 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 Three Inside Up and Three Inside Down 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

Two scanning 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

Seven independent filters to reduce noise and increase signal quality:

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

Each filter can be enabled/disabled independently.

4-Channel Alert System

Stay informed with multi-channel notifications:

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

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

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 the 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: H4, D1 (Three Inside patterns are most reliable on higher timeframes where harami reversals carry more weight, H4 offers highest signal frequency with 8-12 signals per month)
• Symbols: Works on all Forex pairs, Gold (XAUUSD), Indices, and Crypto pairs
• Account type: Any (demo or live)
• Minimum bars on chart: 500+ for reliable market structure analysis

Installation

1. Download and place in your Indicators folder
2. Drag onto any chart
3. Enable "Allow notifications" in MT5 if using push alerts
4. Adjust Quality Score threshold to control signal frequency (lower = more signals, higher = fewer but stronger signals)

Notes

• This indicator does NOT repaint — signals are confirmed on bar close only
• All calculations use completed bars (bar index 1+) for stability
• Scanner operates asynchronously to prevent chart lag
• Memory-optimized for 24/7 continuous operation

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.
