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.
