The Auction Gap Tracker indicator helps traders identify gaps in the auction process — areas on the chart where there is a lack of participation from either aggressive buyers or sellers.

In the image below, you can see a situation where there were no aggressive sellers across four consecutive price levels, while aggressive buyers were active.
The indicator highlights this imbalance zone with a green rectangle.

Unfinished Settings

Minimum Tick Vol

Defines the minimum volume that the tick in which the 0 occurs must have.

Threshold-max. unfinished

Defines the maximum threshold that the Unfinished must have, specifically if you leave 0 it only tracks the Zero Prints, if you increase it to 1 it also tracks all those price ticks in which only 1 contract was traded in Ask or Bid and so on.

Include Mode

1. Intrabar

Track only the Unfinished occurring inside the bar, thus excluding those occurring on the highs or lows;

2. All

Track all Unfinished that fall within the parameters set by the user;

Min. Num. Of Consecutive Zero

the minimum number of consecutive zeros required to trigger a highlight.

For example, if you set this value to 5, the indicator will only highlight levels where there are five or more consecutive price levels with zero aggressive buyers or sellers.
