Check out the new article: Building a Megaphone Pattern Indicator in MQL5.
Build a megaphone pattern indicator in MQL5 that detects expanding structures on the chart. The article walks through swing identification and refinement, trend line validation, breakout confirmation, and SL/TP projection, with chart objects for lines, labels, and signals. As a result, you get a rule-based implementation that automates pattern detection and produces actionable levels directly in MetaTrader 5.
In this project, we are building an indicator that detects the megaphone pattern, also known as a broadening formation. It is called a megaphone pattern because the structure visually resembles a loudspeaker or megaphone on the chart, where price action becomes increasingly wide as the market progresses.
When price swings grow more aggressive and result in greater gaps between successive swing highs and swing lows, the megaphone pattern emerges. The broadening structure that gives the pattern its name is created as a result of the trend line boundaries progressively moving wider apart due to this expansion. With neither a bullish nor bearish trend establishing steady dominance, this increasing behavior frequently indicates increased uncertainty in the direction of the market.
Four crucial swing points are used in the creation of the structure. We first spot a swing high and then a swing low in a bullish megaphone pattern.
