I have explained that before, I take the top 20 bids and bottom 20 ask and see look at the depth $5 (like $48 to $53) on the bids means there is no density of bids, and $1.20 (like $53.10 to $54.30), means there is a high density of asks, thus a negative tension. And before I started typing this, got back in TASR at a discount here at $51.75, going for the hexa bucker.
