How to read OI build-up
- Rising OI + rising price (long build-up) — fresh long positions entering. Often the strongest directional signal of the four OI quadrants.
- Rising OI + falling price (short build-up) — fresh short positions entering. Bearish positioning gaining conviction.
- Falling OI + rising price (short covering) — shorts exiting into strength. Can fuel sharp up-moves but lacks fresh conviction.
- Falling OI + falling price (long unwinding) — longs exiting into weakness. Often the precursor to a base-building phase once unwinding exhausts.

raw % change in open interest on their near-month futures contract.
It is not a measure of MWPL utilisation or proximity to the
