## What is the difference between these order types?

## Summary
The distinction begins with what the order specifies about price. Read the order label together with its price conditions and the execution information that follows. A market order requests a transaction at the current market price, and its execution price can differ from the price expected when the order was placed. [Investor.gov](https://www.investor.gov/introduction-investing/investing-basics/glossary/market-order) Keep that definition separate from a recommendation about which order to choose.

An order label can be familiar while the details remain unclear. Begin by writing the term you are trying to understand, then identify the source definition. Do not fill a gap with a remembered screenshot or with the price displayed on another screen.

This article explains two terms and a simple way to record their differences. It does not choose an order for a particular account, product, or situation. Keep those decisions within your complete trading plan and the documentation applicable to your account.

## What does a market order specify?

## Summary
Read the market-order definition as a description of the order's request, then keep the expected price and the reported execution price in separate fields. The last traded price is not necessarily the price at which a market order will execute. [Investor.gov](https://www.investor.gov/introduction-investing/general-resources/news-alerts/alerts-bulletins/investor-bulletins-14) A review record needs labels for each price rather than a single unlabeled number.

On a terminology card, create spaces for the order type, the price you observed, the time of that observation, and the execution information you are reviewing. If the exercise contains no execution record, leave that field empty.

Do not turn the empty field into an assumed transaction. Write "no execution record supplied" so a later reader can distinguish missing information from a reported value.

The same discipline applies when reading an explanation. Underline the words that describe the request and circle any words that describe an execution. Keep the two descriptions attached to their own source passages.

## What does a limit order specify?

## Summary
A limit-order definition includes a price condition, but that condition does not establish that a transaction occurred. A purchase limit order can execute at its limit price or below; a sale limit order can execute at its limit price or above. [Investor.gov](https://www.investor.gov/introduction-investing/investing-basics/glossary/limit-orders) Read the direction of the condition carefully and preserve the order's status as a separate part of the record.

A limit order may remain unfilled even when it specifies an acceptable price. [Investor.gov](https://www.investor.gov/introduction-investing/general-resources/news-alerts/alerts-bulletins/investor-bulletins-14)

Make a small comparison card with a field for the stated limit and another for the reported status. Use the language in the source rather than writing "done" merely because a price appears beside the order.

For a historical review, preserve the status shown in the record and its timestamp. If the status is unavailable, mark it unresolved. A price condition and a completed transaction are different questions on the card.

This distinction is enough for the terminology exercise. It is not a reason to choose one order type for a specific trade.

## How do you read a hypothetical price condition?

## Summary
Use a fictional threshold to read the direction of a limit condition, without assuming an execution. Label the example, state whether it describes a purchase or sale condition, and record which prices satisfy that condition. Keep any actual transaction information outside the arithmetic exercise.

Suppose a fictional purchase limit is `102`. On the card, list `101`, `102`, and `103` as candidate prices. Under the cited definition, the first two satisfy the stated purchase-price condition. The third does not. This describes eligibility under a condition, not an observed fill.

Now create a separate fictional sale-limit card at `102`. Under that definition, `102` and `103` satisfy the sale-price condition, while `101` does not. Keep the two cards labeled so the direction of the comparison remains visible.

Add a final field reading "execution not supplied." Leave it that way throughout the exercise. There is no order placement, market replay, or account outcome in these invented values.

This example is illustrative only and does not indicate typical results.

## Which details belong beside the order label?

## Summary
Keep the instrument, order type, stated price condition, timestamp, and reported status together in your review notes. Copy those fields from the record you are reading. Where a term depends on account or product documentation, record the question and its source instead of assuming a universal meaning.

Use a short checklist before summarizing a record:

- What exactly is the order label?
- Which price field am I reading?
- What time belongs to that field?
- Is there a separate execution record?
- Which documentation question remains open?

These are reading questions, not a list of order settings to adopt. A missing field deserves an explicit note. Do not infer the contents of a record you do not have.

If a screen and a document use different labels, preserve both labels and write the discrepancy. Resolve it against the relevant documentation before treating your summary as complete.

## How can you review the terminology?

## Summary
Read your comparison card without the source open, then check each statement against the cited definition. Separate the order's request, its price condition, and any execution record. End with a list of unresolved terms rather than converting the exercise into a decision about a future trade.

Ask someone reviewing the card to point to the field that describes the condition and the field that records what occurred. If the same number serves both purposes without a label, revise the card's organization before using it as a reference.

Preserve the source address and the date of your reading. Keep any later clarification as a dated note. The aim is a transparent vocabulary record that you can return to, with uncertainties still visible.

Trading involves the risk of loss.

## Key takeaways
- Read order labels alongside their price conditions.
- Keep observed prices and execution records in separate fields.
- Treat an unreported status as missing information.
- Label hypothetical arithmetic without implying a transaction.

## Frequently asked questions

### Does this article choose an order type for me?

No. It explains terminology and a way to document questions for your own review.

### What if my record has no execution field?

Mark that information as unavailable rather than filling it with an observed quote.

### Where should account-specific questions go?

Record the exact question beside the relevant account or product documentation.
