Passive Buyer
Order Flow Analysis glossary · Absorption, Exhaustion & Imbalances
Definition
A participant who rests a limit order to buy at or below the current bid and lets the market come to them. Passive buying is inferred from the footprint by large bid volume at a low that fails to produce further price decline — aggressive sellers hit the bid repeatedly, but the resting institutional buyer absorbs every sell and refreshes the bid. The ask volume at the same price is typically small, because aggressive buying is not what is driving the activity.
Passive Buyer in plain English
A passive buyer is the opposite of someone in a hurry: they post a price they're willing to buy at and calmly wait for sellers to come to them. Here's why traders hunt for them — imagine a firehose of sellers blasting sell orders at one price, yet the price refuses to drop, because a big buyer is quietly soaking up every single sale and re-posting their order again and again. On the footprint you spot this as huge bid volume at a low that just won't break lower; someone strong is 'absorbing' all that selling, which often signals the bottom is being defended.
