Short Volume + Half Bollinger Band(Sochan Band)

Short-activity histogram + banded zones for quick context on short pressure.
- Data: FINRA Short Volume (FINRA:<symbol>_SHORT_VOLUME)
Works best: Daily (1D) and higher - Use case: Spot relative extremes in short activity and changing regimes
Overview
SochanBand visualizes FINRA short volume as a histogram and overlays a “Sochan Band” (baseline + zone levels) so you can quickly tell whether current short activity is normal, elevated, or extreme versus its own history.
Timeframes (Important)
- Designed to work properly from Daily (1D) and above.
Daily shows the short-activity context clearly. - Weekly/Monthly aims to keep the reading consistent so higher timeframes remain intuitive.
Source Options
- Short Volume — short activity level
Short Volume × Close — price-weighted short pressure (notional intensity) - Short Ratio — short activity relative to total volume
How to Read
- Histogram expands into higher zones → short pressure building
- Histogram compresses toward the baseline → short activity cooling
- Best used as a context tool alongside price action and trend (not a standalone buy/sell signal)
Notes
- FINRA data availability may vary by symbol/market.

개요
SochanBand는 FINRA 공매도(Short Volume) 데이터를 히스토그램으로 시각화하고, “Sochan Band”(기준선 + 단계별 구간)를 통해 현재 숏 활동이 과거 대비 평균/상승/극단 중 어디에 있는지 직관적으로 확인하도록 돕습니다.
타임프레임 (중요)
- 이 스크립트는 일봉(1D)부터 상위 타임프레임에서 정상 동작하도록 설계되었습니다.
- 일봉에서는 숏 활동의 변화가 가장 직관적으로 보입니다.
- 주봉/월봉에서도 해석이 일관되도록, 상위 TF에서도 읽기 쉬운 형태로 표시됩니다.
Source 옵션
- Short Volume — 숏 활동 크기
Short Volume × Close — 가격을 반영한 체감 압력(명목 강도) - Short Ratio — 전체 거래량 대비 숏 비중
해석 방법
- 히스토그램이 커지며 상단 구간으로 확장 → 숏 압력 강화히스토그램이 기준선 근처로 축소/압축 → 숏 활동 둔화
*단독 신호가 아니라 가격 구조/추세와 함께 “맥락 지표”로 활용 권장
