Does it prevent indicator calculation drift?

Yes, the skill implements new bar detection logic using static variables to ensure calculations only update when necessary, maintaining state efficiency and accuracy.

How does this skill help with blank indicator windows?

It provides standardized patterns for explicit scale setting using INDICATOR_MINIMUM and INDICATOR_MAXIMUM, which is essential for indicators displaying very small decimal values.

Can I use this for multi-timeframe indicators?

Yes, it includes specific patterns for buffer management and warmup calculations that are critical for accurate data alignment across different timeframes.

What is the benefit of using hidden buffers in MQL5?

Hidden buffers (INDICATOR_CALCULATIONS) allow you to store intermediate data and track internal states without cluttering the visual interface of the MetaTrader chart.

分析と監視

Develop high-performance MetaTrader 5 indicators using battle-tested architectural patterns and buffer management techniques.

概要

This skill provides specialized guidance for building custom MQL5 indicators within MetaTrader 5, focusing on robust implementation patterns that prevent common development pitfalls. It streamlines the creation of complex visual tools by providing standardized templates for multi-buffer management, real-time recalculation logic, and precision scaling for small value ranges. Whether you are debugging OnCalculate() or implementing multi-timeframe logic, this skill ensures your indicators are performant, accurate, and free from common issues like rolling window drift or display misalignment.
