Other possible topics for future articles include how to store price distribution data and how to use it in a strategy tester.
Dynamic Swing Architecture: Market Structure Recognition from Swings to Automated Execution
This article introduces a fully automated MQL5 system designed to identify and trade market swings with precision. Unlike traditional fixed-bar swing indicators, this system adapts dynamically to evolving price structure—detecting swing highs and swing lows in real time to capture directional opportunities as they form.
A Non-Trading EA Testing Indicators
All indicators can be divided into two groups: static indicators, the displaying of which, once shown, always remains the same in history and does not change with new incoming quotes, and dynamic indicators that display their status for the current moment only and are fully redrawn when a new price comes. The efficiency of a static indicator is directly visible on the chart. But how can we check whether a dynamic indicator works ok? This is the question the article is devoted to.
