EMA Trend Pullback Strategy with Candle Color Filter & News Filter

1. General Overview:

I am looking for an experienced developer to fix and optimize an existing MQL5 Expert Advisor (or rewrite it if cleaner). The strategy is a mechanical trend-following system based on 3 Exponential Moving Averages (EMAs). It trades the pullback (retracement) to a specific EMA.

The Logic (Abstracted):

• Indicators: Three EMAs (Fast, Medium, Slow). Standard values will be provided privately.

• Trend Definition: Price is above/below the Slow EMA.

• Entry Trigger:

  1. Price pushes away from the Fast EMA (Expansion).

  2. Price retraces back to the Medium EMA.

  3. Crucial Filter (The "Clean Move"): The retracement to the Medium EMA must happen without any opposing candle colors (e.g., for a Long setup, the pullback must consist ONLY of bearish candles until the touch). If a bullish candle appears before the touch, the setup is invalid.

• Risk Management:

  • Stop Loss at the last Swing High/Low.

  • Take Profit at the Fast EMA.

  • Minimum Risk-Reward-Ratio (RRR) check before entry.

3. Current Issues / Bugs to Fix: I have a prototype code, but it has logic errors that need to be fixed:

• Multiple Entries: The bot currently opens multiple trades on the same setup/swing. It needs a "Unique ID" logic per Swing High/Low. 

• Strict Rule: Only one trade attempt per valid Swing High/Low structure.

• Loop/Logic Error: Sometimes the "Clean Move" filter is ignored.

4. Requirements:

• Money Management: Adjustable Lot Size.

• News Filter: Integration of a News Filter to stop trading during High Impact News.

• Code Quality: Clean, commented source code (mq5). No DLL imports.

• Visuals: Debug comments on the chart (e.g., marking the "valid" swing).

5. Deliverables:

• Fully functional .ex5 and .mq5 file.

• Backtest results proving the "One Trade per Swing" fix works.
