The Unfinished Auction indicator highlights areas on the chart where the market has unfinished business — meaning the auction process did not complete properly.
To understand this concept, it’s important to first distinguish between a Finished Auction and an Unfinished Auction.
Finished Auction
A finished auction occurs when price reaches a high or low where there is presence of both aggressive buyers and aggressive sellers — indicating that both sides participated in the auction at that level.
This suggests that the market successfully completed its exploration in that direction.

Unfinished Auction
An unfinished auction, on the other hand, occurs when the market reaches a high or low without the presence of the opposite side’s aggression.
In the example below, the high shows 60 aggressive sellers, but zero aggressive buyers above that level — indicating an unfinished auction.
Such levels often act as magnets for price, as the market may revisit them later to “finish the business” left incomplete.

The Unfinished Auction indicator from DeepChart allows us to highlight "anomalies" in the trading auction. In fact, normally in the high tick of a candle we will find a 0 in Bid and x contracts traded in Ask while in the low tick we will find x contracts traded in Bid and 0 in Ask, when this is not the case, that is, when there are contracts traded on the high tick in Bid or the low tick in Ask, the indicator will show a rectangle.
