What Is a Market Not Held Order & How Does It Work?

A market not held order is a specific instruction provided to a brokerage firm, combining elements of a standard market order with a crucial discretionary component. This type of order empowers a broker to use their judgment regarding the timing and price of a trade, aiming to achieve the best possible execution. It represents a nuanced approach to trading, where immediate execution is balanced with the potential for more favorable terms through professional discretion.

Understanding Standard Market Orders

A standard market order is an instruction to buy or sell a security immediately at the best available current price. This order type prioritizes the speed of execution, ensuring that the trade is completed as quickly as possible. When an investor places a market order, they are indicating a willingness to accept the prevailing market price, whatever it may be, to secure an immediate transaction.

Brokerage firms generally execute market orders with utmost urgency. The order is sent to a market or market maker who stands ready to buy or sell the security. While execution is typically rapid, often within seconds for highly liquid assets, the exact price received may differ slightly from the price observed when the order was placed due to market fluctuations. This difference, known as slippage, is a common characteristic of market orders, especially in volatile conditions.

Market orders are frequently used when an investor’s primary goal is to establish or exit a position without delay, such as for large-capitalization stocks or exchange-traded funds (ETFs) that trade with high volume. They are considered the simplest and most common type of transaction, often being the default setting for many brokerage accounts. However, the emphasis remains on guaranteeing execution rather than a specific price point.

The “Not Held” Instruction

The “not held” instruction, when added to a trading order, grants a broker significant discretion over the timing and price of the execution. This instruction relieves the broker of the obligation to execute the order immediately at the next available price. Instead, it allows the broker to wait for what they believe to be a more opportune moment or price point within the trading day.

This discretion means the broker can observe market conditions, such as volatility or liquidity, before proceeding with the trade. The investor, by adding “not held,” waives the right to hold the broker accountable for any potential losses that might arise from delays or missed opportunities while the broker exercises this judgment.

The “not held” designation applies to the broker’s handling of the order, providing flexibility in how and when the trade is executed, rather than defining the type of order itself. This is distinct from a “held” order, which mandates immediate execution without any broker discretion over timing or price.

Executing a Market Not Held Order

When a market not held order is placed, it means the underlying instruction is to buy or sell at the best available price, but the broker has discretion over the timing of that execution. The broker will monitor the market for conditions deemed favorable to achieve the desired outcome for the client. This involves assessing factors such as current market volatility, the depth of liquidity, and the overall size of the order.

For instance, if a large order is placed, an immediate execution might significantly impact the market price, leading to an unfavorable outcome. In such cases, the broker might strategically break the order into smaller parts or wait for periods of higher liquidity to minimize market impact.

The broker’s discretion under a “not held” instruction is generally limited to the trading day. This means they are expected to execute the order before the market closes, unless specific instructions dictate otherwise.

Implications for Investors

For investors, placing a market not held order means relinquishing precise control over the exact timing of their trade’s execution. This introduces a degree of uncertainty regarding the specific price and time at which the transaction will ultimately settle.

The final execution price for a market not held order may differ from the price observed when the order was initially placed. This is a direct consequence of the broker’s discretionary timing, as market prices can fluctuate throughout the day. Investors choosing this order type are relying on their broker’s expertise to secure a more favorable price or to mitigate adverse market impacts, particularly for larger trades where immediate execution could move the market.

This order type is often suitable for situations where the investor values the broker’s ability to navigate complex market conditions more than strict adherence to immediate execution. Investors should understand that while the broker aims for the best possible execution, they are typically not held liable for any potential losses resulting from their discretionary decisions, provided regulatory requirements are met.
