$STBL 15-minute futures open interest increased by 15.44%; the price rose 19.95% over the same period.
The most direct way to tell whether money is flowing into futures contracts is to look at open interest—but you need to understand what the number means.
An increase in open interest means new positions have been opened. A decrease means positions have been closed, either voluntarily or through forced liquidation.
The point of understanding an indicator is to avoid being misled by the numbers, not to use it to pinpoint tops and bottoms.
