Welcome to the continuation of the MQL5 series, focusing on automating the detection of the Gartley harmonic pattern. This relies heavily on Fibonacci levels, price swings, and chart objects. The EA will evaluate price swings, calculate significant Fibonacci retracement and extension levels, and identify possible Gartley formations on a chart. These concepts also apply to other harmonic patterns, including the Bat and Butterfly.

For buy logic, the EA detects bullish Gartley patterns by analyzing points X, A, B, C, and D to match specific retracement rules, then generates a buy order anticipating price reversals. Users can adjust retracement and extension settings.

In the bearish logic, the EA searches for a swing high at point X, followed by identifying points A, B, C, and D to confirm a valid bearish Gartley pattern based on predefined criteria and...

In the continuation of our trading strategy development in MQL5, we have built a Supply and Demand Trading System leveraging a retest and impulse model. This system identifies supply and demand zones through periods of consolidation, confirms their validity with impulsive price moves, and facilitates trading on retests.

Key components of this strategy include defining risk parameters, implementing trend confirmation, and enhancing chart visualization with dynamic labels and colors. We covered the framework, implementation in MQL5, key enumerations, zone detection and validation, trading logic, and the integration of trailing stops. This comprehensive approach provides a functional trading strategy in MQL5 to efficiently manage supply and demand zones for potential reentry trades.

The article delves into an intricate challenge faced by MetaTrader 5 developers: effective communication between the Chart Trade indicator and the Expert Advisor to manage futures contracts. The proposed solution involves using message exchanges between these components, carefully addressing sequence and synchronization issues when MetaTrader 5 changes the chart timeframe. A notable approach is implementing custom events to smoothly adjust contract types and maintain user interface consistency without convoluting systems. This innovative strategy enhances flexibility in contract management while keeping interface components separate, emphasizing the importance of structured message passing for improved algorithmic trading applications.

The Volume-Weighted Moving Average (VWMA) is gaining traction as a crucial tool for traders, providing an edge by integrating trading volume into price analysis for trend verification. Unlike traditional moving averages like SMA and EMA, the VWMA assigns more significance to price movements with substantial trading volume, capturing genuine market momentum.

For algorithmic trading, VWMA's practical application offers enhanced trend confirmation by focusing on significant volume-backed price changes. The MQL5 implementation of VWMA crossovers involves using both a fast and slow VWMA to identify bullish and bearish market conditions. These signals help in constructing Expert Advisors (EAs) that streamline trade execution, monitor market conditions, and generate actionable alerts. Such advancements bolster traders' capability to differentiate between meaningfu...

A new tool provides a visual representation of trading sessions by aligning them with the 24-hour clock. It synchronizes session names with specific hours based on your broker's server time, while also displaying your computer's local time. The active session or any overlaps are highlighted in yellow, helping to clarify which sessions are live at any given moment. This can reduce uncertainty regarding session timings and potential overlaps with server times, streamlining the trading process and enhancing situational awareness for traders managing multiple time zones.

Support and resistance zones are crucial concepts in technical analysis, serving as key psychological barriers for traders. Understanding these levels is essential as they significantly influence market participants' decisions. Support zones indicate areas where buying pressure exceeds selling pressure, causing price rebounds. Conversely, resistance zones denote levels where selling pressure halts upward movement.

The focus here is to automate the identification of these zones using an EA. By analyzing recent price data, the EA can spot swing highs and lows, pivotal for defining these zones. A swing low is characterized by a candle with a low price lower than its preceding and succeeding candles, while a swing high has a higher price.

For support zones, the EA logs relevant data, such as swing low time and price, ensuring no candle breaks below this zone t...

A new strategy to visualize wick regions on lower-timeframe charts has been initiated. The primary goal is to enhance the Market Periods Synchronizer, integrating a Wick Visualization Utility. This tool isolates the upper and lower wick regions of higher-timeframe candles, rendering them with semi-transparent rectangles for detailed analysis.

To implement this, several technical steps are crucial. Initialization involves setting up a mutable UI for real-time interactions using a CCanvas bitmap label. This ensures efficient use of screen real estate while maintaining per-chart isolation through specific naming conventions.

The core logic focuses on rendering wicks only when a toggle is active. This involves calculating the top and bottom of candle bodies, and highlighting their wicks distinctly above and below these thresholds. These regions are prog...
