Dual Engulfing Pro MT5 Candle Signals Multi Filter

### Product Overview

The Engulfing Dual-Engine and Multi-Filter Confirmation Indicator for MetaTrader 5 is a specialized technical analysis analytical tool engineered to identify directional engulfing candlestick patterns across global financial markets. Developed for quantitative analysts, discretionary traders, and algorithmic strategy designers, the software categorizes engulfing structures into two distinct computational classifications: Standard Retail Engulfing and Advanced Institutional Engulfing. Rather than evaluating candlestick geometry as an isolated variable, the indicator incorporates a modular confirmation framework featuring 14 independent technical filters. This architecture enables users to cross-validate raw price action against directional momentum shifts, baseline moving averages, volatility expansion thresholds, structural horizontal boundaries, and dynamic Fibonacci golden zones before any visual arrow is plotted or notification dispatched.

The indicator operates deterministically on closed candle data (Bar 1 indexing). This mathematical structure ensures that plotted arrow signals, internal data buffers, and multi-channel alerts remain completely static once a candle completes. No plotted values shift, recalculate, or repaint across historical chart data. The software exposes four discrete numeric indicator buffers, facilitating direct integration into automated trading systems, Expert Advisors (EAs), and multi-symbol scanner utilities via the native iCustom programmatic interface.

### Operating Principles and Candlestick Pattern Logic

The indicator evaluates market dynamics through two distinct candlestick geometry models coupled with a multi-layered validation architecture:

1. Retail Engulfing Model (Standard Structure)

The retail pattern detects conventional two-bar reversal formations where the real body of the current candle completely covers the real body of the immediately preceding candle:

- Bullish Retail Setup: Bar [1] must be a bearish candle (Close < Open), and Bar [0] must close as a bullish candle (Close > Open). The open price of Bar [0] must be less than or equal to the close of Bar [1], while the close of Bar [0] must be greater than or equal to the open of Bar [1]. When directional trend context is enabled (InpRetailRequireTrend = true), the algorithm requires a predefined sequence of consecutive opposing candles (default: 2 consecutive bearish candles) prior to the signal bar to confirm an active corrective or trend-reversal impulse.

- Bearish Retail Setup: Bar [1] must be a bullish candle (Close > Open), and Bar [0] must close as a bearish candle (Close < Open). The open price of Bar [0] must be greater than or equal to the close of Bar [1], while the close of Bar [0] must be less than or equal to the open of Bar [1]. When trend context is required, the setup must be preceded by a sequence of consecutive bullish candles (default: 2 consecutive bullish candles).

2. Institutional Engulfing Model (Advanced Liquidity Structure)

The institutional pattern expands upon classical geometry by enforcing five computational validation criteria that model aggressive volume injection and directional commitment from institutional market participants:

- Real Body Engulfment: The real body of the signal candle must encompass the real body of the preceding candle (Open[0] <= Close[1] and Close[0] >= Open[1] for bullish; Open[0] >= Close[1] and Close[0] <= Open[1] for bearish).

- Outside Bar Conformation: When full outside bar validation is active (InpRequireFullOutside = true), the extreme boundaries of the signal candle must completely exceed the prior bar (High[0] > High[1] and Low[0] < Low[1]). This reflects an initial liquidity sweep of previous extreme liquidity followed by decisive directional displacement.

- Body Expansion Ratio: The absolute body size of the signal candle (|Close - Open|) must equal or exceed the previous candle body multiplied by the user-defined multiplier (InpBodyMultiplier, default: 1.5x), identifying expansion velocity.

- Relative Volume Expansion: When active (InpRequireHigherVolume = true), the tick volume or real exchange volume of the signal bar must strictly exceed the volume of the preceding bar (Volume[0] > Volume[1]), confirming increased participant engagement.

- Decisive Close Placement: The close price must terminate within the extreme upper or lower percentage of the total candle range (High - Low). For bullish setups, the close must settle within the upper bracket (default: upper 30%, calculated as (Close - Low) / Range >= InpMinClosePosition = 0.70). For bearish setups, the close must settle within the lower bracket ((High - Close) / Range >= InpMinClosePosition = 0.70).

- Structural Preceding Context: When enabled (InpInstRequireTrend = true), the setup requires a sequence of consecutive opposing bars (InpInstTrendBars, default: 3 bars) to verify directional displacement against prior movement.

3. Signal Calculation and Non-Repainting Guarantee

Calculations are executed sequentially across historical bar data. Visual arrow signals and alert routines are evaluated at index bar 1 upon completion of the bar. Because all price relationships, moving averages, oscillator levels, and volume parameters are finalized when a bar closes, signals plotted on the chart and recorded in data buffers do not change. Historical chart evaluations reflect real-time live trading behavior.

### Modular 14-Filter Quantitative Confirmation Engine

The indicator features an onboard multi-filter engine comprising 14 modular technical filters. Traders can enable any single filter or combine multiple layers simultaneously. When multiple filters are active, the indicator enforces logical conjunction (AND logic), requiring all enabled conditions to be satisfied concurrently before a signal arrow is rendered:

1. Relative Strength Index (RSI) Cross Filter

- Logic: Monitors momentum transitions out of oversold or overbought extremes using standard RSI calculations.

- Buy Condition: RSI[current] crosses above Oversold threshold (default: 30.0) from RSI[prior] <= Oversold.

- Sell Condition: RSI[current] crosses below Overbought threshold (default: 70.0) from RSI[prior] >= Overbought.

- Purpose: Identifies momentum exhaustion and immediate reversal emergence from extended pricing boundaries.

2. Average Directional Index (ADX) Trend Strength Filter

- Logic: Assesses directional movement intensity regardless of direction using Wilder's directional system.

- Buy and Sell Condition: Main ADX line on the signal candle must equal or exceed ADX_Min_Level (default: 20.0).

- Purpose: Prevents signal generation during flat, directionless consolidation phases, restricting entries to conditions exhibiting sufficient directional velocity.

3. Single Moving Average (SMA / EMA) Baseline Filter

- Logic: Compares candle close relative to a single moving average calculated across a defined lookback period.

- Buy Condition: Candle Close is strictly greater than the Moving Average value.

- Sell Condition: Candle Close is strictly lower than the Moving Average value.

- Purpose: Enforces baseline trend alignment, ensuring bullish engulfing signals occur exclusively above the mean and bearish signals occur below the mean.

4. Ichimoku Kinko Hyo - Senkou Span B Filter

- Logic: Employs the longest equilibrium component of the Ichimoku system, Senkou Span B ((Highest High + Lowest Low) / 2 over 52 periods, shifted 26 bars).

- Buy Condition: Candle Close is positioned above the current Senkou Span B buffer value.

- Sell Condition: Candle Close is positioned below the current Senkou Span B buffer value.

- Purpose: Validates structural market polarity across medium-to-long term equilibrium cloud baselines.

5. RSI 75 Long-Term Momentum Filter

- Buy Condition: Fast MA value is strictly greater than the Slow MA value (Bullish Golden alignment).

- Sell Condition: Fast MA value is strictly lower than the Slow MA value (Bearish Death alignment).

- Purpose: Confirms intermediate-term trend structure and directional expansion before allowing setup execution.

  * Histogram Color / Slope Filter: Buy requires AO[current] > AO[prior]; Sell requires AO[current] < AO[prior].

  * Zero-Line Positioning Filter: Buy requires AO > 0 and expanding upward; Sell requires AO < 0 and expanding downward.

- Purpose: Validates market drive and momentum acceleration across multiple sub-algorithmic rules.

8. Parabolic Stop and Reverse (SAR) Trend Filter

- Logic: Calculates trailing price acceleration points based on Step (0.02) and Maximum (0.2) parameters.

- Buy Condition: Candle Close is located above the current Parabolic SAR point.

- Sell Condition: Candle Close is located below the current Parabolic SAR point.

- Purpose: Verifies trade execution remains compliant with parabolic volatility trailing channels.

9. Commodity Channel Index (CCI) Trend Polarity Filter

- Buy Condition: CCI(50) value is greater than 0.0.

- Sell Condition: CCI(50) value is less than 0.0.

- Purpose: Filters out setups occurring on the wrong side of statistical mean deviations.

10. Commodity Channel Index (CCI) Overbought & Oversold Filter

- Logic: Uses a standard 14-period CCI calculation to identify extreme price deviations from the statistical mean.

- Buy Condition: CCI(14) value is greater than the Overbought threshold (+100.0), indicating aggressive upside breakout velocity.

- Sell Condition: CCI(14) value is less than the Oversold threshold (-100.0), indicating aggressive downside breakout velocity.

- Purpose: Validates high-volatility breakout setups when momentum enters statistical tail zones.

11. Relative Vigor Index (RVI) Directional Trend Filter

- Logic: Measures the conviction of recent price action by comparing close-to-open change with high-to-low range across 75 periods.

  * Zero-Level Filter: Buy requires MACD Main line > 0.0; Sell requires MACD Main line < 0.0.

- Purpose: Provides standard classical momentum verification and directional bias separation.

14. Rolling Support and Resistance Zone Filter

- Logic: Evaluates highest high and lowest low levels across a trailing window (default: 50 bars). Computes a proximity tolerance buffer defined in points (default: 80 points).

- Buy Condition: The low boundary of the signal candle penetrates or touches the lowest low support zone (Low <= Support + Zone AND Low >= Support - Zone, or penetrates and closes back).

- Sell Condition: The high boundary of the signal candle penetrates or touches the highest high resistance zone (High >= Resistance - Zone AND High <= Resistance + Zone, or penetrates and closes back).

- Purpose: Ensures signals originate at structural market extremities rather than in random price areas.

15. Dynamic Fibonacci Retracement Golden Pocket Filter

- Logic: Scans backward using configurable ZigZag parameters (Depth 12, Deviation 5, Backstep 3) to identify the two most recent verified swing points (Swing High and Swing Low). It constructs dynamic Fibonacci retracement coordinates across the measured range.

- Buy and Sell Condition: The signal candle range (High to Low) must actively intersect the designated Fibonacci retracement band defined between Level 1 (default: 0.382) and Level 2 (default: 0.618).

- Purpose: Aligns engulfing price action directly with institutional harmonic retracement and equilibrium value areas.

16. Heiken Ashi Trend Confirmation Filter

- Logic: Computes real-time synthetic Heiken Ashi candlesticks using standard weighted formulas: HA_Close = (Open + High + Low + Close) / 4; HA_Open = (HA_Open[prior] + HA_Close[prior]) / 2.

- Buy Condition: The synthetic Heiken Ashi candle is bullish (HA_Close > HA_Open).

- Sell Condition: The synthetic Heiken Ashi candle is bearish (HA_Close < HA_Open).

- Purpose: Eliminates noisy micro-ticks and ensures directional consistency through synthetic smoothing.
