What is trading?
FOUNDATIONS: COURSE 1 | LESSON 4
Order types: market, limit, stop, stop-loss, take-profit
Learning objectives
By the end you can choose the right order type — market, limit or stop — for any entry idea, and place it on the correct side of the price.
By the end you can attach a stop-loss and take-profit to a position and explain exactly what each will do (and not do).
By the end you can explain slippage and gaps, and why a stop-loss is essential despite not being a guarantee.
So far you can size a trade and read your account's vital signs. Now: how do you actually tell the platform what you want? Orders are your entire vocabulary for talking to the market. There are only five words in it, and by the end of this lesson you'll speak all five fluently — which puts you ahead of a surprising number of live-account traders who click Buy and improvise from there.
Market orders: "now, please"
A market order executes immediately at the best available price — you buy at the ask, sell at the bid (D1.4). It's the right tool when being in the trade now matters more than the exact price: the setup is live, the level you wanted is trading this second.
The cost of immediacy: you accept whatever price is there when your order arrives. In calm conditions on EUR/USD that's the quoted price or a fraction of a pip away. In fast markets — during news, at market open — the fill can differ from what you clicked by several pips. That difference is slippage, and it's not the broker cheating; it's the price genuinely changing in the milliseconds your order travelled. Slippage can favour you too, but plan as if it won't.
Pending orders: "only at my price"
A pending order is an instruction that waits: if price reaches level X, execute. This is how you trade levels without staring at charts all day — and, more importantly, how you pre-commit to a plan while calm instead of improvising while adrenalised. There are two families, and the difference is direction-of-approach:
Limit orders — expecting a bounce/pullback. You want a better price than now.
- Buy limit: placed below current price. "EUR/USD is at 1.0850; I'll buy if it dips to 1.0800." You believe the dip is a discount, not the start of a slide.
- Sell limit: placed above current price. "If it rallies to 1.0900, I'll sell there."
Stop orders — expecting a breakout/continuation. You want confirmation that price can move through a level, and you're willing to pay a worse price for it.
- Buy stop: placed above current price. "It's at 1.0850; if it breaks 1.0900, I want in on the momentum."
- Sell stop: placed below current price. "If it cracks 1.0800, I'll sell the breakdown."
A mnemonic that has saved thousands of misplaced orders: limit = "I want it cheaper/richer" (better price), stop = "I want it confirmed" (worse price). If you place a buy limit above the market by mistake, most platforms execute it instantly at the ask — congratulations, you've made an accidental market order. Always sanity-check: is my pending order on the correct side?
Pending orders can carry an expiry (GTC — good till cancelled — or a specific time). Review your working orders weekly; markets move, and a forgotten limit order from three weeks ago can fill in the middle of a news storm you'd never have chosen to trade.
Stop-loss and take-profit: the exits you attach
A stop-loss (SL) is an order attached to your position that closes it if price moves against you to a set level. A take-profit (TP) closes it at a set level in your favour. Both then work 24/5 without you — through the night, through your day job, through the moments your discipline would have wobbled.
Worked example, tying together the whole course so far. Account $2,000, risk 1% ($20). Long EUR/USD:
- Entry: buy limit at 1.0800 (expecting a pullback from 1.0850).
- Stop-loss: 1.0760 — 40 pips below entry. Size = $20 ÷ (40 × $10) = 0.05 lots. If wrong, you lose ~$20. Decided in advance, sized in advance.
- Take-profit: 1.0880 — 80 pips above entry. If right, you make ~$40.
That's a 1:2 risk-reward trade fully specified before entry — entry, exit-if-wrong, exit-if-right, size. This four-line structure is a trade plan (F2.2 builds on it), and every piece was placed while you were calm. The alternative — entering first, deciding exits "when I see how it goes" — is how positions become hostages and traders become hostages-with-opinions.
Where do the levels come from? The stop goes where your trade idea is invalidated — beyond the recent swing low, outside the range — not at a round dollar amount that feels comfortable. Then size makes the money-risk right (F1.2). Never the reverse: moving a stop closer to afford a bigger size is risk management performed backwards.
What a stop-loss doesn't promise
Time for the honest print. A standard stop-loss triggers when price reaches your level, then closes at the next available price. Usually that's your level or within a pip. But:
- Gaps. A stock CFD closes Friday at $180 with your stop at $176; bad news lands over the weekend and it opens at $158. Your stop executes at ~$158, not $176. Forex gaps too, over weekends — smaller, but real.
- News spikes. A shock announcement can move EUR/USD 60+ pips in seconds with thin liquidity between prices. A stop at 1.0800 might fill at 1.0794 — 6 pips of slippage on the worst possible trade.
Some brokers offer guaranteed stop-losses on some instruments for a premium; standard stops are not guaranteed. Does that make stops pointless? Precisely the opposite conclusion: an unstopped position in those same scenarios loses unboundedly more. The stop-loss is the seatbelt that mostly works and occasionally lets you bruise; trading without one is declining the seatbelt because it isn't an airbag. And the deeper protections remain the ones you've already learned: modest size, sensible instruments, and not holding leveraged positions blind through known event risk.
One last tool: after a position moves well into profit, you can move the stop to the entry price ("breakeven") or trail it behind the price. Powerful, but easy to overdo — F2.4 covers managing open trades without strangling them.
Key takeaways
Market orders buy immediacy and accept slippage; pending orders buy price control and accept the trade may never trigger.
Limits sit on the better side (buy below / sell above); stops on the worse side (buy above / sell below). Wrong side = accidental instant execution.
Every position should carry a stop-loss placed where the idea is invalidated, with size derived from the stop distance — never the reverse.
An entry + SL + TP + size, set while calm, is a complete trade plan; deciding exits mid-trade is where discipline goes to die.
Stops trigger at your level but fill at the next available price — gaps and news slippage are real, and the answer is stops plus sane sizing, not no stops.
