Market Order vs Limit Order (When to Use Each)
Market vs limit is the smallest decision in trading and the one most beginners get wrong. Used right, it saves you slippage. Used wrong, it costs you fills and money.
Every trade entry is one of two basic order types: a market order or a limit order. They sound similar but they behave completely differently. Understanding when to use each is foundational, and it's something most beginners pick up by accident rather than deliberately. The Candleread desk uses both — market orders in some scenarios, limit orders in others — and the choice always comes down to which problem you're trying to solve.
A market order says "fill me at whatever the current price is, right now." You click buy, the broker matches your order against the best available offer, and you're filled instantly. The advantage: guaranteed fill. You know you're in the trade. The disadvantage: you don't control the price. If the market moves between your click and the broker matching the order, you get filled at whatever's available — which might be worse than what you saw on screen. This difference is slippage, and it can be ugly during fast markets.
A limit order says "only fill me at this exact price or better." Buy limit at 1.0850 means "only buy if price is 1.0850 or LOWER." Sell limit at 1.0900 means "only sell if price is 1.0900 or HIGHER." The advantage: you control the price. No slippage — you either get the price you wanted or you don't get filled at all. The disadvantage: you might not get filled. If the market never reaches your limit, you sit on the sidelines and miss the trade entirely.
When to use a market order. When you need to be in the trade RIGHT NOW. Examples: closing a losing position to cut losses, entering on a confirmed breakout where the move is happening, exiting at a target where you don't want to risk missing the fill. In these scenarios, certainty of execution matters more than the few pips of slippage you might give up.
When to use a limit order. When you have a specific price you want and you're willing to wait. Examples: entering on a planned pullback to support, entering on a planned breakout with a specific entry trigger, scaling into positions in pieces. In these scenarios, price precision matters more than guaranteed execution. Most professional trade entries are limit orders because pros plan their entries in advance — they know exactly where they want to be in.
The biggest mistakes. Mistake one: using market orders during news. Spreads blow out, slippage spikes, and you can pay 5-10x the normal entry cost. Use limit orders or stay out. Mistake two: using limit orders for stop losses. Limit orders only fill at your price or BETTER — which means a stop limit might not fill at all if price gaps through, leaving you with a worse loss. Use stop market orders for stops, not stop limits. Mistake three: setting limit orders so far away from current price that they never get filled. The market doesn't owe you your dream entry — be realistic.
Key takeaways
- ✓Market order = instant fill, possible slippage
- ✓Limit order = exact price or better, possible no fill
- ✓Use market for urgency (cutting losses, confirmed breakouts)
- ✓Use limit for price precision (planned entries, pullbacks)
- ✓Never use limit orders for stop losses — use stop market
Frequently asked
Which is cheaper, market or limit?+
Limit, almost always. Market orders pay the spread plus any slippage. Limit orders pay just the spread (or even cross the spread to your favor on ECN brokers). For active traders, the savings from using limits add up to thousands of dollars per year.
Can I cancel a limit order if I change my mind?+
Yes, anytime — as long as it hasn't been filled yet. Pending limit orders sit on the order book until they're either filled or cancelled. You can adjust them, cancel them, or let them expire (some brokers auto-cancel after a set period).
What's a stop limit order vs a stop market order?+
A stop market becomes a market order when triggered — guaranteed fill but possible slippage. A stop limit becomes a limit order when triggered — no slippage but might not fill if price moves too fast. For stop losses, always use stop market. For entries on breakouts, stop limits can work.
Are limit orders always free of slippage?+
Yes, by definition. A limit order will only execute at your specified price or better — never worse. The trade-off is fill probability: in a fast-moving market, the price might skip past your limit and never come back, leaving you unfilled.
