Order Types Cheat Sheet
Lock in the orders you learned — fast drills
Read
Same market, same second — two traders click “buy” and get different prices. That is not luck; it is which order they used.
On the desk, the difference between a good trade and a painful one is often not the idea — it is the order you used to express it. Same pair, same second, two traders: one gets filled at a great price, the other pays up. Pick the right tool and the market works with you.
An order is an instruction to your broker on how to execute a trade. Orders give you control over your entry, your exit, and your risk — the whole shape of the trade.
This is your cheat sheet: a fast, side-by-side review of the order types from the previous lesson, with each one broken down to purpose, a worked example, and its trade-offs.
Getting your order executed is getting filled. A market order fills now; a resting limit or stop order sits working in the market until price comes to it.
Market Order
A market order is executed immediately at the best available price. It prioritizes speed over price — it gets you in or out fast, which matters most in a fast-moving market.
When a fill matters more than the price
To guarantee you get filled, right now. Use it when being in the trade matters more than shaving a fraction of a pip off the entry.
Buying 1,000 euros at the ask
• You want to buy 1,000 euros (EUR) with U.S. dollars (USD).
• The current market for EUR/USD is 1.0850 / 1.0852 (bid / ask).
• You send a market order to buy, and it fills immediately at the ask of 1.0852.
• You receive 1,000 euros; your account is debited the dollar equivalent at that exchange rate.
Getting in or out fast on a liquid pair, when certainty of execution beats a slightly better price.
Why it nearly always fills
• Near-certain execution: as long as there are buyers and sellers, you get filled.
• Simplicity: the most basic order there is — hard to get wrong.
• Speed: fills almost instantly, so you can act on an opportunity the moment you see it.
The price you never agreed to
• No price control: you accept whatever price is available — you might pay more, or sell for less, than you saw on screen.
• **Slippage risk:** in fast markets the price can move between the click and the fill, so you get a worse price than expected.
• Poor fit for thin markets: in an illiquid pair a market order can fill at a badly skewed price.
A market order buys certainty of a fill, not certainty of a price. Around news releases or in thin, fast markets, the gap between the price you saw and the price you got — the slippage — can be brutal.
Limit Order
A limit order names your price and refuses everything worse. The trade-off is plain: a market order guarantees a fill and not a price, a limit order guarantees a price and not a fill.
Setting the worst price you will accept
To control the exact rate you enter or exit at. You set the worst price you will accept: the most you will pay to buy, or the least you will take to sell.
Waiting for 1.0800 to come to you
• You want to buy 1,000 euros, but only if EUR/USD drops to 1.0800 or lower.
• You place a buy limit order at 1.0800.
• It sits working and will not fill unless the market trades at 1.0800 or better.
Patient entries and exits where price matters more than speed — buying a dip or selling a rally at a level you chose in advance.
What naming your price buys you
• Price control: you get your price or better — never worse.
• Reduced slippage: because you name the price, you sidestep unfavorable surprise fills.
• Works in any conditions: liquid or thin, calm or volatile.
The trade that never happens
• No guarantee of execution: if the market never reaches your price, nothing happens.
• Missed moves: if price runs the other way, you can be left behind entirely.
• Requires patience: the market may take its time getting to your level — if it ever does.
Stop Order
A stop order is an instruction to buy or sell once price reaches a specified level, the stop price. When the stop is triggered, it becomes a market order and fills at the next available price.
A stop order has two distinct uses. As a stop-entry order it opens a position when price breaks through your level (buy above the market, sell below) — a breakout tool. As a stop-loss order it closes an existing position to cap your losses. This section focuses on the stop-loss use.
Stop-entry = get me in if price breaks through this level. Stop-loss = get me out if price turns against me past this level. Same mechanism, opposite purpose — do not confuse them.
The safety net under an open trade
As a stop-loss, to limit the loss on an open trade. It is your safety net — it closes the position automatically if the market moves against you past a level you set.
A stop-loss 100 pips below your entry
• You are long (bought) EUR/USD at 1.0850.
• To protect the trade, you set a stop-loss at 1.0750.
• If price falls to 1.0750 or below, the stop triggers and your position closes at the next available price — capping the loss at roughly 100 pips.
Defining your risk before you need it — every position should have one. Set it the moment you enter, then step away from the screen.
Why every open trade wants one
• Risk management: the single most important tool for controlling losses.
• Peace of mind: your downside is defined, so you can leave the screen without babysitting the trade.
• Automated exit: you are taken out of a losing trade even if you are not watching.
Triggered means filled, not filled well
• No guaranteed price: once triggered it becomes a market order, so volatility can fill you worse than your stop level.
• False triggers: a brief spike can knock you out just before price recovers.
• Placement is an art: too tight and you get stopped out on noise; too wide and it barely protects you.
Stop Limit Order
A stop limit order combines a stop and a limit. It triggers when price reaches your stop price — but instead of becoming a market order, it becomes a limit order at your limit price.
The trade-off is the mirror image of a plain stop. A stop order guarantees execution but not price; a stop limit guarantees price but not execution. It only fills at your limit price or better — and if price blows past that level, it may not fill at all.
Stop protection without the slippage
To get the protection of a stop without the slippage — you refuse to be filled at a price worse than your limit, accepting the risk that you might not be filled at all.
A stop at 1.0750, a limit at 1.0700
• You are long EUR/USD at 1.0850.
• You set a stop limit with a stop at 1.0750 and a limit at 1.0700.
• Price falls to 1.0750 — the stop triggers, arming a limit order.
• That limit only fills at 1.0700 or better. If price gaps straight through 1.0700, you may be left holding the position.
Traders who would rather stay in than exit at a terrible price — useful in calm markets, risky in fast ones.
A stop limit protects you from a bad fill, but it can also leave you unprotected. If price gaps clean through your limit, the order never triggers a fill and your loss keeps running. That is the price of demanding a price.
What the second price protects
• Price control: fills only at your limit or better — no slippage.
• Risk management: still automates your exit when price hits the stop.
• Flexibility: you tune both the stop and the limit to your strategy.
Still holding when price gaps through
• No guarantee of execution: if price gaps past your limit, the order may never fill.
• Partial fills: in fast markets only part of your order may fill at the limit price.
• Needs watching: after the stop triggers, you may have to manage the position if the limit does not fill.
Trailing Stop Order
A trailing stop order is a stop-loss that follows price as it moves in your favor — but never moves back against you. As the trade gains, the stop ratchets up behind it, locking in more and more of the move.
You set it as a distance — say 50 pips — not a fixed level. The stop trails that far behind the best price reached, tightening your worst-case exit as the trade works.
Letting a winner run without giving it back
To let winners run while protecting the profit already banked. It manages the exit for you and takes the emotion out of moving a stop by hand.
A 50-pip trail that banks 50 pips
• You are long EUR/USD at 1.0850 with a 50-pip trailing stop.
• Price rises to 1.0900, so the stop trails up to 1.0850 (50 pips below) — your worst-case exit is now breakeven.
• Price keeps rising to 1.0950, and the stop trails up again to 1.0900 — now locking in 50 pips of profit.
• Price then falls back to 1.0900: the trailing stop triggers and closes your position. You keep the 50 pips of locked-in profit instead of giving it all back.
That is locking it in — using a trailing stop to convert an open, paper gain into profit the market can no longer take away. The stop only moves one direction: with you, never against.
Riding a trending move you want to let run, without watching the screen or guessing where the top is.
Why it beats moving the stop by hand
• Captures more of a trend: the winner runs as long as price keeps going your way.
• Automatic: the stop adjusts itself — no manual dragging.
• Removes emotion: it stops you from bailing early or letting a winner turn into a loser.
When a normal pullback ends the trade
• No guaranteed price: once triggered it becomes a market order, so the fill can differ from the stop level.
• False triggers: a normal pullback can trail you out just before the move continues.
• Distance matters: too tight and noise stops you out; too wide and you give back too much.
Good Till Cancelled (GTC) Order
A Good Till Cancelled (GTC) order stays active in the market until it fills or you cancel it. It does not expire at the end of the day. GTC is a duration setting you attach to other orders, like limits and stops.
An order that waits as long as you do
To set an order in advance and let it wait for the market to come to you — ideal for longer-term traders who cannot watch the screen all day.
A buy limit left at 1.1000
• You think EUR/USD will eventually climb to 1.1000; it is currently 1.0850.
• You place a GTC buy limit order at 1.1000.
• It stays live until price reaches 1.1000 or you cancel it — days or weeks later if need be.
Setting a level and forgetting the screen — orders that should survive past today’s session.
Why longer-term traders default to it
• Flexibility: set orders ahead of time with no worry about them expiring overnight.
• Convenience: no re-entering the same order every morning.
• Long-term trading: perfect for price moves you expect to play out over weeks.
• Price control: like any limit, you decide the exact rate you enter or exit at.
The order you forgot you placed
• No guarantee of execution: if price never reaches your level, the order simply waits indefinitely.
• Missed moves: price can spike toward your order and reverse before filling, leaving you out.
• Needs periodic review: a GTC order you forgot about can fill long after the idea behind it went stale.
One Cancels Other (OCO) Order
An One Cancels Other (OCO) order links two orders together — typically a limit and a stop. If one fills, the other is cancelled automatically. It is a complete exit plan in a single ticket.
Arming both exits at once
To automate both sides of your exit at once. The moment your target profit or your maximum acceptable loss is hit, the position closes and the other order disappears.
Take profit at 1.0950, stop at 1.0750
• You are long EUR/USD at 1.0850.
• You want to take profit at 1.0950 and cap the loss at 1.0750.
• You place an OCO: a sell limit at 1.0950 and a sell stop-loss at 1.0750.
• Whichever hits first executes; the other is cancelled on the spot.
Setting your whole exit plan — profit target and stop — in one move, then walking away.
Why the pair works better than either alone
• Automated risk management: both exits are armed at once, no monitoring required.
• Profit and protection together: a take-profit and a stop-loss working as a pair.
• Removes emotion: your plan is set in advance, so there is nothing to second-guess in the moment.
• Flexible: tune the target and the stop to your own risk tolerance.
Where OCO lets you down
• Not offered everywhere: some brokers do not support OCO — check before you rely on it.
• Requires understanding: set it up wrong and you can get an exit you did not intend.
Summary
Every order is a different answer to the same two questions: how do I get in, and how do I get out?
Market orders prioritize speed — fill me now, at the going price. Limit orders prioritize price — fill me here or better, or not at all.
Stop orders are your safety net (and, as stop-entries, your breakout tool), while stop limit orders trade the certainty of a fill for control over the fill price.
Trailing stops let a winner run and lock the profit in behind it. GTC keeps an order alive until it fills or you kill it, and OCO pairs a target and a stop so one cancels the other.
Speed or price — a market order fills now, a limit order holds out for your price. A stop protects (get me out) or breaks out (get me in); a trailing stop follows a winner and locks profit in one direction only. GTC keeps an order working until you cancel; OCO fires one exit and cancels the other.
