A Limit Price Controls a Boundary, Not a Promise That an Order Will Fill

A worked trading example can make an order look like a completed purchase merely because a price has been entered. The order’s instruction and its eventual execution are separate pieces of the story.

Investor.gov’s explanation of order types describes a buy limit order as executable only at the limit price or lower, and a sell limit order at the limit price or higher. Setting that boundary does not guarantee execution.

In a fictional example, a buy limit of $25 does not authorise a purchase at $26. If the relevant market conditions do not allow a fill within the limit, the order may remain unfilled according to its duration and handling rules.

Keep the example’s missing fields visible

Record the order type, side, quantity, limit and time-in-force. Then distinguish submitted, partially filled, fully filled, cancelled and expired where those states are relevant. A screenshot showing the submitted price cannot establish which later state occurred.

Also separate the limit from a stop price. Different order types use these values differently; combining their names into a vague “target price” hides an important instruction.

Use a paper example to learn the vocabulary rather than placing a trade just to test a label. Actual order behaviour depends on the product, venue and broker’s rules. A clear reading note should explain what the instruction permits and what the example still has not shown.
