Open Interest Open Interest (OI)
The total number of outstanding F&O contracts not yet settled or closed. वे सभी F&O contracts जो अभी तक settle या बंद नहीं हुए हैं।
Open interest (OI) is the total count of active futures or options contracts not yet closed, squared off, or delivered. Rising OI with rising prices signals fresh buying (bullish); rising OI with falling prices signals fresh short-selling (bearish). Traders watch OI build-up at specific Nifty strikes — heavy call writing often acts as a ceiling; heavy put writing acts as a floor. OI differs from volume, which counts all contracts traded in a session regardless of whether positions were opened or closed.
Open interest (OI) उन active futures या options contracts की कुल संख्या है जो अभी तक close, square off, या deliver नहीं हुईं। बढ़ती कीमतों के साथ बढ़ता OI fresh buying का संकेत देता है (bullish); गिरती कीमतों के साथ बढ़ता OI fresh short-selling का संकेत देता है (bearish)। traders Nifty strikes पर OI build-up देखते हैं — भारी call writing अक्सर ceiling का काम करती है; भारी put writing floor का। OI, volume से अलग है — volume एक session में trade हुए सभी contracts गिनता है, चाहे positions खुली हों या बंद।
