Dominance EA - expert for MetaTrader 5

Dominance EA

At its core, Dominance EA is a minimalist, bias-driven trading system built around a simple but powerful idea: market dominance. Rather than reacting to every tick or micro-pattern, the EA steps back and evaluates which side of the market—buyers or sellers—controlled the previous trading day, then aligns its next action with that dominant force.                                      

Core Concept — Dominance

The EA defines dominance using two complementary layers:

1. Structural Dominance (Bar Count)
   • It iterates through all candles formed during the previous day.
   • Counts:
     • Bullish candles (close > open)
     • Bearish candles (close < open)
   • The side with the higher count establishes directional control.
2. Contextual Confirmation (MA Positioning)
   • The final candle of the previous day is evaluated against a Moving Average.
   • This acts as a filter, ensuring that dominance is not just numerical, but also structurally aligned with trend positioning.

Only when both conditions agree does the EA establish a valid bias:

• Buy Bias → Bullish dominance + close above MA
• Sell Bias → Bearish dominance + close below MA

An optional Inverted Mode allows contrarian trading by flipping this logic—useful for mean-reversion or experimental strategies.

Execution Logic

Once a valid daily bias is established:

• The EA checks for existing positions (ensuring one-trade-per-symbol discipline).
• If no trade is open, it executes a single position per day in the direction of the bias.

This creates a clean operational cycle:

Analyze yesterday → Decide today → Execute once → Stand down

Risk & Trade Management

The EA adopts a conservative and broker-compliant execution model:

• Minimum Volume Trading
  • Trades are placed using SYMBOL_VOLUME_MIN , ensuring compatibility across brokers and reducing risk exposure.
• ATR-Based Stop Loss
  • Stop Loss is dynamically calculated using:
    • Previous day’s high/low
    • Expanded by an ATR multiple ( atrMultiplier )
  • This ensures volatility-adjusted protection rather than fixed pip distances.
• Risk-to-Reward Structure
  • Take Profit is set at 2× the Stop Loss distance, enforcing a consistent reward profile.
• Pre-Trade Validation
  • Stop level compliance (broker constraints)
  • Margin availability checks
  • Tick-level price validation

Key Inputs

The EA exposes a concise but powerful configuration surface:

• Model Behavior
  • eaMode → Normal or Inverted logic
• Trend Filter
  • maPeriod , maMethod , maAppPrice
• Volatility & Risk
  • atrPeriod , atrMultiplier
• Execution Controls
  • ordFillType → Order filling policy
  • eaMagic → Trade identification
  • tradeComment → Logging & traceability

These inputs allow both strategic flexibility and execution control without overcomplicating the system.

What You’ll Learn 

This EA goes beyond strategy—it’s a practical lesson in engineering disciplined trading systems in MQL5:

• How to design a time-filtered trading model (daily bias systems)
• Structuring logic around market state instead of tick noise
• Using indicator handles (MA, ATR) efficiently
• Implementing safe trade execution pipelines with margin and stop validations
• Designing modular, maintainable code using structs and functional separation
• Enforcing one-trade-per-cycle logic for cleaner backtesting and analysis

Final Insight

Dominance EA is intentionally simple in appearance but deliberate in design. It strips trading down to a single question:
