CISD

**CISD – Continuous Implied Structure Displacement (Body-Based Version)**

CISD displays structure levels derived from a simple sequence:
1. A valid pullback (based on body closes only)
2. Followed by a displacement (a body-based break in the opposite direction)

When these two conditions occur, the script prints a CISD level at the pullback’s reference price.
Each CISD level extends forward until price closes through it using body logic only.

### How this version works

**1. Pullback Detection (Body-Only)**
A pullback is recognized when a candle’s body meaningfully retraces the previous candle’s body.
Tiny candles are filtered out, reducing noise and improving level quality.

**2. CISD Formation**
After a valid pullback, if price breaks structure in the opposite direction using body highs/lows only:
- A **Bullish CISD** level is created from a bearish pullback
- A **Bearish CISD** level is created from a bullish pullback

**3. CISD Completion**
When a CISD level is violated by a full body close beyond the level, the CISD is marked completed and a new opposite CISD becomes eligible.

**4. Visual Output**
- Clean horizontal CISD levels
- Single active level per direction (unless extended manually)
- Labels marked “CISD” for clarity

### What this indicator is *not*
This tool does **not** generate trade signals or provide financial advice.
It is a visual mechanism for observing how price reacts to pullback-based structural shifts using body logic only.

### Intended Use
CISD can help users:
- Track transitions in short-term structure
- Identify when pullbacks lead to meaningful displacement
- Observe reaction points derived strictly from body behavior (ignoring wicks)

The logic is minimalistic and designed for clean, uncluttered structure observation.
