Over $ARC 1 hours, open interest increased by 155.37%; the price rose by 2.28%.
In other words, price and open interest both went up, which I take to mean that longs are adding to their positions.
An increase in open interest means someone is opening new positions; a decrease means someone is closing positions. You can’t tell the direction just from this alone.

Just sharing for reference—don’t copy this blindly. Make your own decisions.
