Is this compatible with both MT4 and MT5?

This specific skill is optimized for MQL5 (MetaTrader 5) syntax and buffer architectures, which differ significantly from the older MT4 system.

Can this skill handle multi-timeframe indicators?

Yes, it includes logic for buffer alignment and recalculation patterns essential for multi-timeframe (MTF) development.

How does this skill help with blank indicator windows?

It provides specific patterns for setting IndicatorSetDouble minimum and maximum scales, which is the primary cause of blank displays for values below 1.0.

How does it prevent indicator drift?

It uses a 'New Bar Detection' pattern with static variables to ensure logic only executes when necessary, maintaining state accuracy across ticks.

Does it support both visible and hidden buffers?

Absolutely, it implements the INDICATOR_DATA and INDICATOR_CALCULATIONS patterns to separate display values from internal calculations.
