Tipos de órdenes explicados: mercado, límite, stop y stop-límite (y cuál te sale caro)
Quick answer: a market order guarantees you get in, not at what price. A limit order guarantees the price, not that you get in. A stop order triggers when price arrives and becomes a market order. A stop-limit adds a price cap to that trigger — which is exactly why it can fail to fill at the moment you most need it. That last sentence is the one that costs accounts.
Puntos clave
- Every order chooses between certainty of filling and certainty of price. You never get both.
- A market order into a high-impact release is the most expensive way to enter.
- A normal stop loss is a stop order: it becomes a market order and can slip.
- A stop-limit used as a stop loss can leave you holding a position you thought was closed.
All four, in one table
| Order | Guarantees | Does not guarantee | Typical use |
|---|---|---|---|
| Market | That it fills | The price | Get in or out now, whatever it costs |
| Limit | Your price or better | That it fills | Waiting for a pullback to your level |
| Stop | That it triggers on arrival | The fill price | Stop loss, or breakout entry |
| Stop-limit | The price, if it fills | That it fills | Breakouts where you refuse to overpay |
The mistake that costs the most
Never use a stop-limit as your stop loss. If price gaps past your limit, the order sits unfilled and you are still holding a position you believed was closed — in exactly the violent move you wanted protection from. For protecting capital, the plain stop order is the right one: it accepts slippage in exchange for actually getting you out.
When to use each one
| Situation | Recommended order | Why |
|---|---|---|
| Entering in liquid hours, no rush | Limit | Removes entry slippage |
| Closing a position now | Market | Getting out matters more than price |
| Protecting capital | Stop | Always executes, even with slippage |
| Breakout entry without overpaying | Stop-limit | You would rather miss it than chase it |
| The minute of a macro release | Ninguna | Spread and slippage decide for you |
That last row is the most important and the least respected: in that minute the order type barely matters, because the execution cost outweighs any edge you think you have.
Details that change the outcome
- Minimum distance. Many brokers reject a stop placed too close to price; check the symbol specification.
- Expiry. A pending order with no expiry can trigger days later, in a context that no longer exists.
- Partial fills. On larger lots, part of the order can fill at one price and part at another.
- Weekends. A pending order left open on Friday can fill into Monday's gap.
- Server-side stops. A stop placed in the platform lives on the broker's server; a “mental” one does not exist.
How to reduce decisions
Every order is one more decision, and repeated decisions under pressure are where mistakes appear. The Cortex Signal Kit delivers signals with entry, stop and target already defined, so the order type stops being improvised; Cortex Automation places them in your MetaTrader 5 with the same rules every time. For the execution-cost side, the free ebook The True Cost of Trading covers what spread and slippage take from you.
What is the difference between a stop and a stop-limit?
A stop becomes a market order when triggered and fills no matter what. A stop-limit becomes a limit order, and if price runs past it, it may never fill.
Can I set a stop loss and take profit at the same time?
Yes, and it is standard. In MetaTrader 5 they attach to the position and live on the broker's server.
Do limit orders avoid slippage?
On entry, yes. For an emergency exit they are no help, because the risk is precisely that they do not fill.
Why did my pending order not trigger?
Usually broker minimum distance, an expired order, or price touching the level with the other side of the spread.
What does an automated system use?
It depends on the logic, but typically market or stop to enter, and always a stop to protect.
Less improvisation in execution. See the Cortex Signal Kit and Cortex Automation.
