Check out the new article: Price Action Analysis Toolkit Development (Part 51): Revolutionary Chart Search Technology for Candlestick Pattern Discovery.

This article is intended for algorithmic traders, quantitative analysts, and MQL5 developers interested in enhancing their understanding of candlestick pattern recognition through practical implementation. It provides an in‑depth exploration of the CandlePatternSearch.mq5 Expert Advisor—a complete framework for detecting, visualizing, and monitoring classical candlestick formations in MetaTrader 5. Beyond a line‑by‑line review of the code, the article discusses architectural design, pattern detection logic, GUI integration, and alert mechanisms, illustrating how traditional price‑action analysis can be automated efficiently. 

Candlestick patterns remain one of the most enduring and visually intuitive tools in technical analysis. They capture the ongoing struggle between buyers and sellers, leaving behind a clear record of market sentiment and momentum. Traders and developers alike continue to revisit this subject because candlesticks are, in many ways, the true footprints of price action. They reflect where the market has been and, quite often, hint at where it might go next. Every candlestick formation tells a story about what has occurred at a particular price level and time. These formations have been studied, named, and classified for decades, each carrying its own forecasting implications. A well‑known example is the bullish engulfing pattern, which is often seen as an early sign of renewed buying strength.  

The continued interest in candlestick analysis within MQL5 development stems from hands‑on experience in the market. The more one observes live price behavior, the more challenges emerge—and with them, opportunities to create smarter solutions. MQL5 proves to be an exceptionally rich environment for that creativity; its flexibility allows technical ideas to evolve into complete, working tools capable of analyzing charts automatically and visually.

This article introduces CandlePatternSearch.mq5, an Expert Advisor designed to extend the traditional study of candlestick formations through automation and interactivity. The system scans and detects a wide range of common patterns and allows users to search for specific ones directly on the chart. Detected formations are visually marked, making it easier to explore how each pattern has influenced price across different instruments and timeframes. Over time, this capability helps traders recognize recurring market behaviors and build confidence in anticipating probable outcomes when certain patterns appear.
