Orders in Trading: The Complete Guide to Selection and Usage

When you first start trading, one of the first things you need to understand is what an order is and how to use it. An order is essentially a instruction for the trading platform to execute a buy or sell of an asset under certain conditions. There are many types of orders, each designed to solve different trading tasks. Understanding the differences between them is critical for developing an effective trading strategy.

What is an order in trading and why is it needed

An order is not just a command to buy or sell. It is a powerful tool that allows traders to automate their actions, manage risks, and lock in profits. In a broad sense, an order serves as a bridge between your trading decision and its execution in the market.

When you place an order, you give the platform instructions to act according to specific parameters. This could be immediate execution at the current price, execution when a certain price level is reached, or even automatic closing of a position under certain conditions. Everything depends on the type of order you choose.

In the modern cryptocurrency market, trading without understanding order types is like driving a car without knowing how to use the gear shift. You can move, but doing so inefficiently and exposing yourself to unnecessary risks.

Three main types of orders for beginner traders

Before moving on to complex financial instruments, you need to master three basic types of orders. They form the foundation of all trading and are essential for understanding more advanced strategies.

Market order: maximum speed

A market order is the simplest and fastest way to make a trade. When you place such an order, it is executed immediately at the best available price in the market. If you are buying, you get the ask price; if selling, you get the bid price.

The main advantage of a market order is its speed. In volatile markets where prices can change in milliseconds, quick execution can be decisive. However, there are downsides: you do not control the final execution price, which can lead to slippage—the difference between the expected and actual price.

Additionally, market orders typically incur higher fees (taker fee) because you are taking liquidity from the market rather than adding it.

Limit order: control over price

A limit order gives you direct control over the price at which you are willing to buy or sell. You specify an exact price level, and the order will only be executed if the market reaches that price or better.

For example, if you want to buy Bitcoin at $40,000 instead of paying the current market price of $45,000, you place a limit order. If the price drops to $40,000 or below, your order will automatically be filled.

The major advantage of a limit order is lower fees (maker fee) if the order enters the order book and adds liquidity. The main drawback is the possibility that the order may not be filled if the market never reaches your specified price.

Important: when placing a buy limit order, the price should be set below the current market price; otherwise, it will execute immediately as a market order. Conversely, for sell orders, the price should be above the current market price.

Conditional order: trading automation

A conditional order is a tool for those who want to automate their trading strategy. Such an order is not activated immediately but waits for a specific condition to be met, usually reaching a certain price level (trigger).

There are two subtypes of conditional orders:

Conditional market order — when the trigger price is reached, the system places a regular market order, which is executed immediately.

Conditional limit order — when the trigger activates, the system places a limit order at the specified price.

Conditional orders are often used to create stop orders (entry on breakout) and take-profit/stop-loss orders (exit at profit or loss).

Advanced orders: tools for experienced traders

After mastering basic order types, traders can move on to more complex tools that offer greater flexibility and more risk management options.

Take-profit and stop-loss: managing exits

If a conditional order automates entry into a position, then take-profit (TP) and stop-loss (SL) orders manage exits.

A take-profit order will automatically close your position when a certain profit level is reached. For example, if you bought Bitcoin at $40,000 and set a take-profit at $50,000, the order will close at that price, locking in your profit.

A stop-loss order works the opposite way: it protects you from excessive losses. If you bought an asset at $40,000 and set a stop-loss at $35,000, the position will close if the price drops to that level, limiting your losses.

Combining TP and SL is the foundation of risk management in trading.

Iceberg order: hidden large trades

If you need to execute a large order but don’t want to cause market panic with your huge trade, an iceberg order is your solution.

An iceberg order breaks a large trade into multiple smaller orders that are gradually sent to the market. This way, the market only sees a part of your order (the visible part of the iceberg), while the rest remains hidden below the surface.

This helps avoid significant price impact and slippage when executing large positions. Market makers and large traders often use this tool.

OCO order: one cancels the other

OCO (One Cancels Other) is a way to place two related instructions simultaneously. Usually, these are two conditional orders: one for profit, another for protection against losses.

If the first order triggers (for example, the price jumps and the take-profit is hit), the second order is automatically canceled. This is convenient because you don’t have to manually cancel the protective stop-loss after reaching your profit target.

Post-Only order: guaranteed maker fee

A Post-Only order guarantees that you will receive a maker fee (lower fee) rather than a taker fee. The system will place such an order in the order book only if it does not result in an immediate trade.

If the condition is not met (the market price already exceeds your price), the order is simply canceled. This tool is for those who want to add liquidity to the market and earn lower fees.

Reduce Only: decrease without increasing

Reduce Only orders allow you to only decrease an open position, not increase it. This protects against accidentally opening a new position when you intend to exit.

For example, if you have a long position of 5 Bitcoin, a Reduce Only order will allow you to sell up to 5 Bitcoin but will not open a short position if you try to sell more.

TWAP and scaled orders: smart distribution

TWAP (Time Weighted Average Price) orders distribute the execution of your large trade evenly over time. Instead of buying everything at once at a single price, the system makes multiple purchases during the specified period, aiming for an average price over that period.

Scaled orders work similarly but distribute the order across a price range rather than over time. This reduces market impact and helps achieve a better average price.

Trailing stop and follow-price limit order

A trailing stop automatically moves the stop-loss level along with favorable price movements. If you entered a position and the price moves in your favor, the trailing stop moves accordingly, locking in profits and protecting against reversals.

A follow-price limit order dynamically adjusts the price of your limit order based on market movements, helping you get a better execution price.

Orders with expiration: timing matters

There are three options for how long an order remains active:

GTC (Good-Till-Canceled) — the order remains active until it is executed or you cancel it manually. It can stay in the book for days or weeks.

IOC (Immediate or Cancel) — the order is executed fully or partially immediately, and any unfilled part is canceled. Market orders typically follow this principle.

FOK (Fill or Kill) — the order must be fully executed immediately; otherwise, it is canceled entirely. This is a “all or nothing” approach.

How to choose the right order for your trading strategy

Choosing the order type depends on your trading strategy, market conditions, and comfort level.

For scalping and high-frequency trading, market orders and IOC orders are suitable for quick execution.

For swing trading, limit orders and conditional orders are useful for entering at desired levels and automating your strategy.

For position trading, combinations of TP/SL and Post-Only orders are effective for risk management and reducing fees.

For large trades, iceberg orders, TWAP, and scaled orders help avoid excessive market impact.

The key principle: select tools that match your goals, time horizon, and level of expertise. Start with basic types and gradually incorporate more complex instruments as your trading experience grows.

Conclusion: mastery in trading begins with understanding orders

An order is the fundamental language through which a trader communicates with the market. It’s like understanding grammar for a writer—without it, you cannot effectively express your ideas.

From simple market orders to complex TWAP, each tool is designed to solve specific tasks. Deep understanding of all these instruments transforms a beginner into an experienced trader capable of adapting strategies to any market condition.

Invest time in learning different order types, practice on a demo account, and gradually incorporate new tools into your real trading. Such solid knowledge of trading instruments separates successful traders from casual speculators. Remember: in trading, it’s not only about where you want to go but also how you get there, and orders are your roadmap.
