WHAT IS THE COST OF CARRY RESULTING IN BULLISHNESS / BEARISHNESS

Open interest and change in CoC are indicators of wider sentiment about the stock or index. Open interest refers to the number of open positions within a contract. An increase in CoC is indicative of bullish accumulation, while a fall in CoC can indicate bearish additions and short positions. A fall in OI accompanied by a rise of CoC indicates the closure of short positions. Falling OI and CoC indicate that traders are closing long trades. Analysts can also see changes in CoC after the expiry date of derivatives contracts. Bullishness is indicated by a large number of positions being rolled over at a higher cost of carrying.
