What Is a Not-Held Order?
Placing a stock order usually feels instant: choose a price, click submit, and the trade fills or it doesn’t. A not-held order works differently, handing part of that timing decision to whoever is executing the trade on the other end.
The short answer
A not-held order tells a broker or trading desk that it is not required to execute the trade immediately or at the exact price quoted the moment the order was entered. Instead, the broker gets discretion over timing and price, and may work the order in pieces over minutes or hours to try to get a better overall result. It’s used mostly for large orders where dumping the whole trade on the market at once could move the price against the trader.
How it differs from a standard order
Most retail trades are “held” orders, which means the broker is expected to send them to the market and execute promptly at the best available price, with little room for judgment calls. A market or limit order placed through an ordinary brokerage account is a held order by default. A not-held order flips that expectation: the trader gives up the promise of immediate execution in exchange for the broker’s judgment about how and when to work the order. That judgment can mean breaking a large order into smaller pieces, waiting for a moment when there’s more liquidity, or routing pieces to different venues as conditions change.
Why discretion can matter for large orders
A single large order hitting the market all at once can be visible to other participants and can push the price away from the trader before the full order is filled. That effect is sometimes called market impact. By giving a broker room to time the trade, a not-held order aims to reduce that impact, spreading execution out so the price paid or received reflects more of an average across the trading session rather than a single unfavorable moment. This trade-off comes with uncertainty of its own: because execution isn’t immediate, the final price is not locked in when the order is placed, and the market can move for reasons that have nothing to do with the order itself while it’s being worked.
Who typically uses this order type
Not-held orders are mainly a tool for institutional-style trading rather than everyday retail investing. A brokerage account opened for individual investing rarely offers this order type directly, since most retail trades are small enough that market impact isn’t a meaningful concern. Where it shows up is with larger blocks of shares, program trades involving many securities at once, or situations where a trader specifically wants a desk’s judgment rather than an automatic routing decision. Firms handling these orders generally still operate under best execution obligations that require them to seek favorable terms even while exercising discretion.
How discretion interacts with order routing
Because a not-held order isn’t tied to a single moment or venue, it also opens up more flexibility in how the trade gets to the market. The broker working the order may adjust which venue or counterparty it sends pieces to as prices and available liquidity shift throughout the day, similar in spirit to how order routing decisions work for smaller trades, just with more active management involved. The added flexibility is the point: a rigid, immediate execution isn’t always the best outcome for a trade large enough to move a thinly traded market.
What to weigh
A not-held order is a trade-off between certainty and flexibility. Giving up the guarantee of an immediate, known execution price in exchange for a broker’s discretion can help with size and market impact, but it also means accepting some uncertainty about exactly when and at what price the trade will ultimately complete. Understanding which type of order is being placed, and why, is generally the more useful question than assuming one approach is automatically better than the other.
