Hello, futures positions, also known as controlled positions or open positions, refer to the number of commodity futures contracts that have not been hedged and delivered in kind after buying or selling.

The yellow line above the volume is the line of positions held on that day. As long as the change of positions on the day is displayed, if the position is increased on the day, the position line will go up, and vice versa. On the right side of the software, you can see whether the position is increased or decreased on that day, which are marked. Positions are calculated on a bilateral basis. I hope my answer can help you.
