open interest
Compares the open interest recorded now with the value this hub recorded itself at the start of the window, so both numbers come from the same source and the same basis. Notional value is always taken with the price of its own point in time, never recomputed with the current price. price_change_pct and volume_change_pct cover exactly the same window from the recorded minute candles. interpretation follows a rule printed in the answer, so a buyer can recompute it: price and open interest.
