FX Order Types | Market, Limit, and Stop Orders, and Closing Positions (SL/TP) Basics for Beginners

Even once you understand how FX works, opening the actual trading screen can leave you stuck on “which order button do I press?” When names like market order, limit order, stop order, OCO, and IFD are all lined up, they can look intimidating at first glance alone.

As the practical follow-up to STEP01, this page organizes order types into two groups: “orders you place right now” and “orders that reserve a price for later.” If you first cover the underlying mechanics of FX itself in What Is FX?, the meaning of entries and closing positions covered here will click into place more easily.

Market Orders — Buying or Selling Immediately at the Current Price

A market order buys or sells as quickly as possible at the market price currently displayed. It’s convenient when you don’t want to miss an opportunity or want to close a position right away, but it doesn’t guarantee execution at the exact price shown the moment you click.

Especially when prices are moving fast, the price shown when you pressed the order button and the price at which the order actually fills can differ slightly. This is called slippage, which is covered later in this article. Market orders are convenient, but precisely because they are “orders placed in a hurry,” you need to decide your position size and stop-loss beforehand.

Limit and Stop Orders — Reserving a Price for Later

A limit order is a reservation to buy or sell once the price reaches a level that’s favorable to you. As a rule, you place it below the current price for a buy and above the current price for a sell. It’s a convenient order type when you don’t want to jump in impulsively and would rather wait for a pullback or a retracement.

A stop order is a reservation that triggers when the price moves in a direction that’s unfavorable to you. Its classic use is a stop-loss: placed below a long position and above a short position. It’s also used to target breakouts — buying once a high is broken, or selling once a low is broken. It’s important not to confuse which side, above or below, it should be placed on.

OCO and IFD — Combining Reservations

An OCO (One Cancels the Other) order places two orders simultaneously, and when either one is filled, the other is automatically canceled. For example, you can place a take-profit and a stop-loss on an open position at the same time — whichever one is hit first, the other side disappears.

An IFD (If Done) order is a reservation that places a closing order once a new entry order is filled. Combine IFD with OCO and you can design the entry, take-profit, and stop-loss all together in one setup. That said, just because it’s convenient doesn’t mean you should stack too much complexity into it — it’s easy to lose track of what the order was actually meant to achieve. It’s more realistic to start with simple combinations and build familiarity from there.

Closing Orders — Take Profit (TP) and Stop Loss (SL)

In FX trading, how you exit tends to affect your results more than how you enter. An order that locks in a profit is called take profit (TP), and an order that caps a loss is called stop loss (SL). For both, deciding before you enter a trade keeps you steadier than scrambling to figure it out after you’re already in.

SL in particular is a safety device that keeps your loss fixed at a small amount. Placing SL/TP at the same time as your entry makes it easier to avoid the emotional mistake of delaying a stop-loss. For specifics on stop-loss distance and money management, see Stop-Losses and Money Management.

Slippage and Execution

Execution means an order is actually filled. It isn’t enough to simply place the order on screen — the trade must be matched on the broker’s server before it’s reflected as an open position or a closed one.

Slippage is the phenomenon where the price you ordered at and the price your order is actually executed at diverge. It tends to happen around events like employment reports or policy rate announcements, when prices move quickly and liquidity tends to thin out. Market orders are especially exposed to this, so choosing not to force an entry during major-indicator releases is also a valid option.

Summary

Order types are easiest to understand around three pillars: use a market order to enter right now, a limit order to wait for a favorable price, and a stop order to reserve a stop-loss or a breakout entry. OCO and IFD are convenient combinations, but rather than overusing them from the start, it causes less confusion to treat them as tools for clearly defining where your take-profit and stop-loss sit.

What you need next is how much volume to order. For how to decide your position size, move on to Lot Size Calculation, and for where to actually enter in practice, learn the STEP02 Basic Entry Patterns — that will connect the meaning of the order button to the judgment calls you make on the chart.
