Order types: market, limit, stop
What each order type actually costs you
A market order fills at the best price available right now. On EUR/USD at 1.0850, you get roughly 1.0850, but the price can move between your click and the fill. That movement is a cost you cannot see in advance. The spread is also charged on every market order, and it varies between brokers.
A limit order waits for a better price than the current one. If you want to buy, you set your limit below 1.0850. If you want to sell, you set it above. The order only fills if the market reaches your price. You may wait minutes or days, and the order may never fill. The cost is the waiting itself, plus the risk that the price moves away without you.
A stop order triggers once the market reaches a worse price than the current one. If you are buying, you set the stop above 1.0850. If you are selling, you set it below. When the price touches your stop, it becomes a market order and fills at the next available price. That fill can be worse than your stop level, especially in fast markets. The cost is the slippage between your trigger and your fill.
How the naira cost changes with the order type you pick
One pip on one standard lot of EUR/USD is 10 units of the quote currency. If the exchange rate is ₦1,600 to the dollar, one pip is ₦16,000. That figure is fixed for the example, but the real rate changes daily. Use the current rate when you calculate your own costs.
A limit order that waits for a better price can save you pips. If you buy at 1.0835 instead of 1.0850, you save 15 pips. On one standard lot, that is 15 times ₦16,000, which is ₦240,000. That saving is real only if the order fills. If the price never reaches 1.0835, you have no trade and no cost from the order itself.
A stop order that triggers at a worse price costs you pips. If you buy at 1.0875 instead of 1.0850, you pay 25 pips more. On one standard lot, that is 25 times ₦16,000, which is ₦400,000. That extra cost is the price of certainty: the stop gets you in when the market moves your way, but at a worse level. Slippage can add to that cost.
When to use each order type without guessing
Use a market order when you need the trade now and you accept the current price. This is common when you are closing a position to limit a loss. The cost is the spread plus any slippage. You cannot control the fill price, only the decision to trade at all.
Use a limit order when you can wait and you have a specific price in mind. This is common when you want to buy lower or sell higher. The cost is the chance that the order never fills. You may miss a move entirely. Set a limit only at a price you genuinely want, not at a price you hope for.
Use a stop order when you want to enter only after the market moves in a certain direction. This is common for breakout strategies. The cost is the worse entry price plus slippage. Never use a stop order as a limit order. A stop triggers at a worse price by design, so it will always cost more than the current price if it fills.
One idea, three prices, three naira costs
| Step | Amount | Note |
|---|---|---|
| Current EUR/USD price | 1.0850 | the price shown on the chart now |
| Market order entry | 1.0850 | takes the current price immediately |
| Limit order entry | 1.0830 | 20 pips better than the current price, so it waits |
| Stop order entry | 1.0870 | 20 pips worse than the current price, so it triggers only if price moves there |
| Pip value on one standard lot | ₦16,000 | 10 units of the quote currency, converted at ₦1,600 per unit |
| Cost of the 20-pip gap, limit vs market | ₦320,000 | 20 pips x ₦16,000 per pip |
| Cost of the 20-pip gap, stop vs market | ₦320,000 | 20 pips x ₦16,000 per pip |
The broker may quote a slightly different price when your order fills, and may charge a spread, commission or swap on top. These vary between brokers, so check the terms before you trade.
Doing it once, step by step
You will now walk through the three order types on EUR/USD at 1.0850, calculating the naira cost of each choice on one standard lot at ₦16,000 per pip.
- 01
Place a market order
Assume you buy one standard lot at the current price of 1.0850. The fill is at or near 1.0850, but the spread and any slippage apply. Your entry cost is the spread, which varies between brokers. You own the trade immediately.
- 02
Place a limit order 15 pips below
You set a buy limit at 1.0835. If the price falls to that level, your order fills and you save 15 pips compared with 1.0850. On one standard lot, that saving is 15 times ₦16,000, which is ₦240,000. If the price never falls, the order does not fill and you have no trade.
- 03
Place a stop order 25 pips above
You set a buy stop at 1.0875. If the price rises to that level, your order triggers and becomes a market order. You pay 25 pips more than 1.0850. On one standard lot, that extra cost is 25 times ₦16,000, which is ₦400,000. Slippage can make the fill worse than 1.0875.
- 04
Compare the naira outcomes
The market order costs the spread, which varies. The limit order saves ₦240,000 if it fills. The stop order costs ₦400,000 more than the current price if it fills. Each figure assumes one standard lot and ₦16,000 per pip. Change the lot size or the exchange rate and the naira amounts change.
- 05
Check the broker terms before you trade
The broker may quote a slightly different price when your order fills. It may also charge a spread, commission or swap on top. These vary between brokers, so read the terms. No regulator, including SEC Nigeria, sets these charges for you.
- 06
Decide your price first, then the order type
Write down the price you are willing to accept before you click. If you need the trade now, use a market order. If you can wait, use a limit order. If you want to enter only after a move, use a stop order. The order type follows the price decision, not the other way around.
The mistake most people make here
Many beginners use a market order for every entry because it feels simple, then wonder why the fill price is not the price they saw. The screen price can move between the moment you click and the moment the order fills. Others place a stop order to enter and treat it like a limit, forgetting that a stop triggers at a worse price by design. Decide first what price you are willing to accept, then choose the order type that matches it. If you need the trade now, use a market order and accept the current price. If you can wait, use a limit order and let the market come to you.Check yourself
EUR/USD is at 1.0850. You place a limit order 15 pips below the current price. What entry price does that give, and what is the 15-pip gap worth on one standard lot at ₦16,000 per pip?
1.0850 minus 15 pips is 1.0835. The gap is 15 pips x ₦16,000 = ₦240,000.
You place a stop order 25 pips above 1.0850. What entry price does that give, and what is the 25-pip gap worth on one standard lot at ₦16,000 per pip?
1.0850 plus 25 pips is 1.0875. The gap is 25 pips x ₦16,000 = ₦400,000.
Questions that come up next
How much does a market order cost in naira on one standard lot?
The spread is the main cost you see. If the spread is one pip on EUR/USD, that is about ₦16,000 at ₦1,600 to the dollar. The price can also move between your click and the fill, adding slippage. That extra amount varies and is not known in advance. Check your broker's spread before you trade.
How much does a limit order cost if it never fills?
The order itself costs nothing to place. You pay no spread because no trade happens. The cost is that you might miss a move while waiting. That missed move is not a cash cost, but it is a real one. You decide whether waiting is worth it.
How much does a stop order cost when it triggers?
A stop order becomes a market order when triggered. You pay the spread at that moment. You may also pay slippage if the price jumps past your stop. On one standard lot, one pip of slippage is about ₦16,000. The total cost is the spread plus any slippage.
Can I change my order after I place it?
Yes, most platforms let you change or cancel a pending order before it triggers. A market order cannot be changed because it fills immediately. A limit or stop order can be moved to a different price. Check your platform's rules, as they vary between brokers.
What happens if I place a limit order to buy above the current price?
A buy limit must be below the current price to wait for a better price. If you set it above, it may fill immediately at the current price. That defeats the purpose of waiting. Always check that your limit is on the correct side of the market.
How do I know which order type to use?
Decide what price you are willing to accept first. If you need the trade now, use a market order and accept the current price. If you can wait for a better price, use a limit order. If you want to enter only after the price moves a certain way, use a stop order. The choice is about the price you accept, not about speed alone.

- On EUR/USD, one pip on one standard lot is about ₦16,000 at ₦1,600 to the dollar, so each order type has a different naira cost.
- A limit order can save you pips if it fills, but it may never fill, and a stop order costs you pips but gets you in when the market moves.
- The broker may quote a different price at fill and may charge a spread, commission or swap, and these vary between brokers.
