Order Types

An order is an instruction to your broker, and the handful of order types are the entire vocabulary you get for talking to the market. Traders who are fluent in that vocabulary can express any idea precisely: enter now, enter only at a better price, enter only on strength, exit at a defined loss, exit at a defined profit. Traders who aren't fluent end up improvising with the one button they know — and improvised exits are where accounts die.

Every order type below answers two questions differently: do you want certainty of execution, or certainty of price? You can never have both.

Market orders: certainty of execution

A market order says: fill me now, at the best available price. You will be filled almost instantly — buying at the ask, selling at the bid — but the exact price is whatever the market offers in that moment. In calm conditions on a major pair, that's essentially the price on your screen. In fast conditions, slippage applies (as covered in the spread lesson).

Use a market order when being in the trade now matters more than the last fraction of a pip — for example, when price is confirming your setup in real time and waiting means missing it.

Limit orders: certainty of price

A limit order says: fill me only at my chosen price or better.

• A buy limit is placed below the current price — you're saying "if it dips to here, I'll buy the discount."
• A sell limit is placed above the current price — "if it rallies to here, I'll sell the premium."

The trade-off is execution risk: price may never reach your level, and the move you anticipated happens without you. That is not a malfunction — it's the deal you chose. Limit orders suit trades built around levels: buying a pullback into support, selling a retest of resistance, entering inside a zone you identified in advance.

Limit orders also have a quiet economic advantage: instead of paying the spread by crossing it, you're the resting order others trade against, which typically gets you a better effective price than chasing the market.

Stop orders: entering on strength (or weakness)

A stop order inverts the limit's logic. It says: fill me only once price has moved through my level, in the direction of the move.

• A buy stop is placed above the current price — "if it breaks up through here, take me long."
• A sell stop is placed below the current price — "if it breaks down through here, take me short."

Why buy higher than the current price? Because some strategies only want in when the market proves something — a breakout beyond a range, a push through a prior high. The stop order automates that: no confirmation, no trade. Once triggered, it becomes a market order and fills at the next available price, so a violent breakout can fill with slippage.

The two orders that protect you

The entry orders above open positions. These two close them — and they matter more.

Stop loss

A stop loss is a resting order attached to your position that closes it automatically if price reaches a level you define, capping the loss. Long from 1.0850 with a stop at 1.0820? If the market trades down to 1.0820, you're out for a 30-pip loss — whether you're watching, sleeping, or stuck in traffic.

The stop loss is the single most important tool in retail trading, for one reason: it converts an unknowable risk into a known one. Without it, your risk on any trade is "everything, depending on what happens." With it, risk becomes a number you chose in advance — which is the foundation the entire next lesson (risk management) is built on.

Two rules that will save you real money:

1. Place the stop where your idea is wrong, not where the loss feels comfortable. A stop belongs beyond the level that invalidates the trade — under the support you bought, above the high you sold. If that distance implies too much risk, the correct fix is a smaller position, never a tighter, arbitrary stop.
2. Never widen a stop on an open trade. Moving a stop further away to "give it room" is how a planned 1% loss becomes an account-defining one. Stops move one direction only: toward profit.

Take profit

A take profit is the mirror image: a resting order that closes the position at a defined profit level. Set it where your analysis says the move is likely to run out — beyond it, you're hoping, not analysing.

Entering with both a stop loss and a take profit attached means your trade has a defined risk, a defined reward, and therefore a defined risk-to-reward ratio before you commit a cent. That pre-commitment is also psychological armour: decisions made calmly in advance are consistently better than decisions made watching a live P&L flicker.

The six orders at a glance

Some platforms add refinements — trailing stops that follow price at a fixed distance, locking in gains as a trend runs, and expiry settings (good-till-cancelled versus good-for-the-day) on pending orders. Learn them on demo; they're conveniences built on the six primitives above.

Practise until it's boring

On your demo account this week: place each entry type at least once; attach a stop and target to every position; modify them; close half a position early. The goal is that order tickets become as unconscious as typing. When a real setup appears during a fast London open, you want your attention on the market — not on remembering which button means what.
