Order types: market, limit, and stop (mechanics only)
Education only — not a recommendation to buy, sell, or hold anything.
What an order is
An order is an instruction you send to a venue (through a broker or exchange interface) about how you want to trade — size, side (buy/sell), and conditions.
Order type chooses the tradeoff between speed, price control, and certainty of fill. No order type removes market risk.

Market order
Meaning: Trade now at the best available prices.
| Upside (mechanic) | Downside (mechanic) |
|---|---|
| Usually fills quickly in liquid names | You do not control the exact price |
| Simple | Slippage in fast or thin markets |
---
Limit order
Meaning: Trade only at your limit price or better. A buy limit will not pay more than your limit; a sell limit will not take less than your limit (venue rules apply).
| Upside | Downside |
|---|---|
| Price control | May never fill |
| Helps avoid chasing a runaway print | Feels “safe” but still leaves you unfilled in a move |
---
Stop order (stop / stop-market — naming varies)
Meaning (typical stock-broker framing): An order that rests inactive until a trigger price trades (or is quoted), then becomes a live order — often a market order (sometimes called stop-market). Some venues offer stop-limit (triggers a limit instead).
| Upside (mechanic) | Downside (mechanic) |
|---|---|
| Automates a response if price reaches a level | Trigger ≠ fill price; gaps can jump past your level |
| Used in many risk workflows as a concept | Stop-limit can trigger and still not fill |
Naming warning: Apps label “stop,” “stop-loss,” and “stop-limit” differently. Always read that venue’s definition — this page is vocabulary, not a button guide for a specific broker.

Side-by-side
| Order | Primary control | Main uncertainty |
|---|---|---|
| Market | Speed / fill urgency | Final price |
| Limit | Price | Whether you fill |
| Stop (→ market) | Trigger level | Fill price after trigger |
| Stop-limit | Trigger + limit | Fill after trigger and limit |
Crypto venues vs stock brokers
Concepts transfer, but UIs and exact behaviors differ:
- Some crypto platforms emphasize limit and market first; stop tools vary.
- On-chain swaps are not the same as exchange order books — price impact replaces “order type” in many DEX flows.
- Always treat the venue’s own help docs as the ruleset for that product.

What this page deliberately does *not* do
- No “put your stop here” charts
- No entries, targets, or setups
- No broker or exchange rankings
- No promise that any order type makes trading safe

Practice without real money
When /mock/ is live: place market vs limit orders on the same fake symbol and compare fills. Label it FAKE BALANCE. The lesson is mechanics and psychology — not P&L bragging.
