EMA HH/LL Levels v6

1 464
This indicator builds dynamic horizontal levels based on Higher Highs (HH) and Lower Lows (LL) of an Exponential Moving Average (EMA) rather than raw price.
It is designed to highlight structural EMA-based resistance and support levels and automatically manage their lifecycle.

🔹 Core Logic

The script calculates an EMA (default length: 26).

Pivot Highs and Pivot Lows are detected directly on the EMA line, not on price.

Each confirmed:

EMA Higher High (HH) → creates a solid blue horizontal level

EMA Lower Low (LL) → creates a solid red horizontal level

Levels extend to the right and remain active until specific conditions are met.

🔹 Level State Management

Each level can be in one of three states:

Active (Solid line)
The level has been created but not interacted with yet.

Touched by Price (Dotted line)
When a price bar touches the level (High ≥ level AND Low ≤ level),
the level changes its style from solid to dotted, but remains on the chart.

Broken by EMA (Removed)
When the EMA itself crosses the level:

HH level → removed when EMA crosses above it

LL level → removed when EMA crosses below it
The level is then deleted from the chart.

⚠️ Important:
Levels are never removed by price action alone — only by an EMA break.

🔹 EMA Visualization

The EMA line is color-coded by direction:

Upward slope → user-defined “up” color

Downward slope → user-defined “down” color

EMA length, colors, and line width are fully configurable.

🔹 Customization Options

EMA length

EMA up/down colors and thickness

Pivot sensitivity (left/right bars)

HH / LL level colors and thickness

Maximum number of stored levels (to control memory and chart clutter)

🔹 Use Cases

Identifying EMA-based dynamic support and resistance

Tracking trend structure via EMA swings

Confluence with price action, pullbacks, and breakouts

Trend-following and mean-reversion strategies

🔹 Notes

This indicator works on all markets and timeframes.

No repainting after pivot confirmation.

No ta.crossover() / ta.crossunder() is used — all logic is calculated manually for maximum stability in Pine Script v6.
