only the active stocks in f&o should be considered just because they provide clear direction.
try to read the OI data of in the money calls or puts or near the money calls or puts only then you can be little close.
Dear Kiran or Savant or Any expert,
Please evaluate my understanding on the below four situations.
Long Building
People are interested in fresh buying. Thus demand will dominate over supply and the price will rise and also OI will rise.
Conclusion - Price Rise & OI Rise = Long Building
Short Buildup
People are interested in fresh selling. Thus supply will dominate over demand and the price will fall and OI will rise.
Conclusion - Price Fall & OI Rise = Short Building
Long Unwinding
Those who bought the option earlier are selling now. Thus supply will dominate over demand and the price will fall and also OI will fall.
Conclusion - Price Fall & OI Fall = Long Unwinding
Short Unwinding
Those who sold the option earlier are buying now. Thus demand will dominate over supply and the price will rise and OI will fall.
Conclusion - Price Rise & OI Fall = Short Unwinding
