A reduce-only order can only decrease an existing futures position.
It prevents accidental position increases when closing trades.
Reduce-only settings are commonly used with take-profit and stop-loss strategies.
The feature is especially useful in fast-moving markets where manual order management can be difficult.
Reduce-only orders usually apply to position-closing actions rather than opening new trades.
When trading crypto futures, managing an existing position is just as important as opening one.
A reduce-only order is a special order setting that allows traders to close or decrease an existing position without accidentally increasing exposure or opening a position in the opposite direction.
Unlike standard orders, a reduce-only order can only work if it reduces your current position size. If the order would increase your exposure, the exchange rejects or adjusts the order depending on the platform’s rules.
For traders using futures products, understanding how crypto order types work, including reduce-only orders, can help improve position management and avoid unintended trades.
This guide explains what reduce-only orders mean, how they work, their benefits, and how to use them on Bitunix.
A reduce-only order is an order setting that allows a trade to reduce an existing position but prevents it from increasing position size.
In crypto futures trading, traders can open both long and short positions. When managing a position, a common risk is accidentally creating a new position instead of closing the existing one.
A reduce-only order helps avoid this situation.
For example:
A trader holds a 1 BTC long position.
They place a sell order with the reduce-only option enabled.
Possible outcomes:
Order Action | Result |
Sell 0.5 BTC | Long position decreases to 0.5 BTC |
Sell 1 BTC | Long position closes completely |
Sell 1.5 BTC | Extra amount cannot create a new short position |
The reduce-only function ensures the order is used only for reducing exposure.
A reduce-only order checks your current position before execution and only allows the order if it decreases your existing exposure.
The exact behavior may vary slightly between exchanges, but the basic mechanism remains the same.
Example:
A trader opens:
BTC long position: 2 BTC
They create a reduce-only sell order:
Order size: 1 BTC
The order reduces the position:
Previous position: 2 BTC long
Remaining position: 1 BTC long
Now consider a different situation:
Existing position: 0.5 BTC long
Reduce-only sell order: 1 BTC
A normal sell order could potentially create a short position after closing the long.
A reduce-only order prevents this because the additional amount would increase exposure.
The main difference between a regular order and a reduce-only order is whether the order can increase your position.
Feature | Regular Order | Reduce-Only Order |
Can open a new position | Yes | No |
Can increase existing position | Yes | No |
Can reduce position size | Yes | Yes |
Main purpose | Open or manage trades | Close or reduce trades |
Common use case | Entering positions | Managing existing positions |
A regular order gives traders more flexibility.
A reduce-only order adds an additional restriction to make sure the order only decreases exposure.
Reduce-only orders are mainly used to prevent execution mistakes when closing futures positions.
In fast-moving crypto markets, traders may manage multiple orders at the same time, including:
Take-profit orders.
Stop-loss orders.
Partial closing orders.
Manual position adjustments.
Without reduce-only protection, an order intended to close a position could potentially create a new position if the existing position has already changed.
Example:
A trader opens a BTC long position.
They place a sell order to close the trade.
Before execution:
Another take-profit order partially closes the position.
The original sell order remains active.
The market reaches the order price.
Without reduce-only:
The remaining position may close.
The extra quantity may create a short position.
With reduce-only:
Only the remaining position can be closed.
No opposite position is created.
Reduce-only orders help traders maintain better control over futures positions by preventing unintended increases in exposure.
They are especially useful when managing positions with multiple exit strategies or when market conditions change quickly.
One of the main purposes of reduce-only orders is preventing unintended position reversals.
In futures trading, a closing order can sometimes create an opposite position if the order size exceeds the remaining position size.
Example:
A trader has:
Long BTC position: 1 BTC
They place:
Sell reduce-only order: 1.5 BTC
Without reduce-only protection:
1 BTC closes the long position.
The remaining 0.5 BTC could open a short position.
With reduce-only enabled:
Only the 1 BTC position can be closed.
The additional amount will not create a new short position.
Reduce-only orders allow traders to separate position entry and position exit actions.
They are commonly used for:
Closing partial positions.
Taking profits gradually.
Reducing exposure during market movements.
Managing multiple exit orders.
For example:
A trader opens a 5 BTC long position and wants to exit in stages:
Exit Plan | Order Action |
First target | Close 2 BTC |
Second target | Close 2 BTC |
Final exit | Close remaining 1 BTC |
Using reduce-only orders helps ensure these closing orders only decrease the position.
Crypto markets can move quickly, especially during periods of high volatility.
When traders manually adjust positions, mistakes can happen:
Entering the wrong order direction.
Placing an order larger than the remaining position.
Accidentally opening an opposite position.
Reduce-only settings add an extra execution restriction before the order reaches the market.
Reduce-only orders and close-position functions are often confused because both are related to exiting trades.
The main difference is flexibility.
Feature | Reduce-Only Order | Close Position |
Purpose | Reduce part or all of an existing position | Close the entire position |
Partial closing | Yes | Usually no |
Order customization | Yes | Limited |
Can set price conditions | Yes | Depends on platform |
Common use case | Planned position reduction | Quick full exit |
Example:
A trader holds:
10 ETH long position
Using reduce-only:
Close 3 ETH now.
Close another 3 ETH later.
Keep the remaining position open.
Using close position:
Exit the entire 10 ETH position.
Bitunix users can enable the reduce-only option when placing futures orders to ensure the order only reduces an existing position.
Follow these steps:
Select the futures trading pair you want to trade.
Choose the order type, such as limit, market, or conditional order.
Select your margin settings and position direction.
Enter the order quantity.
Enable Reduce Only before submitting the order.
The reduce-only option is typically used when managing an existing position rather than opening a new trade.
Before submitting an order, traders should confirm:
Check Item | Why It Matters |
Correct trading pair | Ensures the order applies to the intended position |
Correct position direction | Prevents closing the wrong side |
Correct quantity | Avoids unexpected execution behavior |
Reduce-only enabled | Ensures the order only reduces exposure |
Reviewing these settings is especially important when managing multiple futures positions.
A reduce-only order may fail when there is no matching position to reduce or when account settings prevent the order from closing a position.
Common reasons include:
Reduce-only orders cannot open new trades.
Example:
Current position: 0 BTC
Reduce-only buy/sell order: submitted
The order cannot execute because there is no position to reduce.
If the order quantity is larger than the existing position, the exchange may reduce the order size or reject it depending on platform rules.
Example:
Current position:
1 BTC long
Reduce-only sell order:
2 BTC
Only the existing 1 BTC position can be reduced.
On some futures platforms, reduce-only functionality may depend on the selected position mode.
If Hedge Mode is enabled, traders may need to switch to One-Way Mode before using reduce-only orders.
If a reduce-only order cannot be placed, check whether Hedge Mode is enabled.
Follow these steps:
Open the futures trading interface.
Select the position mode settings.
Switch from Hedge Mode to One-Way Mode.
Confirm the change.
Position mode availability may depend on the trading product and account settings.
Reduce-only orders are mainly used when traders want to decrease an existing futures position without accidentally increasing exposure.
They are commonly applied in position management scenarios rather than opening new trades.
Traders often use reduce-only orders when they want to secure profits gradually instead of closing an entire position at once.
Example:
A trader opens:
Long BTC position: 2 BTC
The trader expects BTC to continue moving higher but wants to reduce risk.
They set:
Action | Order Size |
First profit target | Sell 0.5 BTC with reduce-only |
Second profit target | Sell 0.5 BTC with reduce-only |
Remaining position | Keep open |
Each order only reduces the existing long position.
If the position size decreases, the remaining reduce-only orders cannot create a new short position.
Reduce-only orders are often paired with exit strategies such as stop-loss and take-profit.
For example:
A trader opens a BTC long position at $60,000.
They set:
Order Type | Purpose |
Take-profit reduce-only order | Close the position if price reaches target level |
Stop-loss reduce-only order | Reduce losses if price moves against the position |
This setup helps prevent an exit order from unintentionally opening a reverse position after the original trade has already been closed.
Fast-moving markets can create situations where traders need to reduce exposure quickly.
Reduce-only orders can help traders:
Lower position size without opening the opposite direction.
Close part of a position during sudden price movements.
Maintain a predefined risk limit.
For example:
A trader holds a leveraged ETH long position but expects short-term volatility.
Instead of closing the entire trade, they place a reduce-only sell order to decrease exposure while keeping part of the position active.
These three order settings are related but serve different purposes.
Feature | Reduce-Only Order | Stop-Loss Order | Take-Profit Order |
Main purpose | Only reduce an existing position | Limit downside exposure | Lock in gains at target price |
Trigger required | No, depends on order type | Usually yes | Usually yes |
Can open a new position? | No | No when configured correctly | No when configured correctly |
Common usage | Position control | Risk management | Profit-taking |
A reduce-only setting does not replace stop-loss or take-profit orders.
Instead, it works as an additional execution condition that restricts what an order can do.
Consider this scenario:
A trader opens a BTC long position.
Current position:
Entry price: $50,000
Position size: 1 BTC
The trader creates two exit orders:
Order | Size | Setting |
Take-profit order | 0.5 BTC | Reduce-only |
Stop-loss order | 1 BTC | Reduce-only |
BTC reaches the profit target.
Result:
The 0.5 BTC order closes part of the position.
The remaining position stays open.
BTC reaches the stop-loss level.
Result:
The stop-loss order closes the remaining position.
No additional short position is created.
Although reduce-only orders are designed to prevent execution mistakes, traders still need to understand how they work.
A reduce-only order only controls the direction of execution.
It does not guarantee that the order will fill.
Execution still depends on:
Market liquidity.
Order type.
Available counterparties.
Price conditions.
For example:
A reduce-only limit sell order may remain open if the market never reaches the selected price.
Before submitting an order, traders should confirm:
Long or short position direction.
Contract quantity.
Trading pair.
A reduce-only order cannot close a position if it does not match the existing exposure.
Multiple reduce-only orders can compete for the same position.
Example:
Current position:
Long BTC:2 BTC
Orders placed:
Order | Size |
Take-profit order | 1.5 BTC |
Stop-loss order | 2 BTC |
If one order executes first, the remaining position changes.
Traders should review active orders to ensure the remaining size matches their plan.
When several reduce-only orders are active, the exchange checks the remaining position before execution.
Example:
A trader has:
Long ETH position: 10 ETH
Active orders:
Order | Size | Purpose |
Take-profit | 5 ETH | Partial profit |
Stop-loss | 10 ETH | Full exit |
If the take-profit order executes first:
Remaining position becomes 5 ETH.
The stop-loss order can only close the remaining 5 ETH.
This prevents the stop-loss order from creating a short position.
To use reduce-only orders effectively, traders should:
Confirm the position direction before placing orders.
Review open orders after partial position closures.
Understand the difference between reducing exposure and opening a new trade.
Combine reduce-only settings with appropriate order types, such as limit or conditional orders.
Reduce-only is a position management tool, not a replacement for a complete trading plan.
Reduce-only orders are a practical tool for futures traders who need tighter control over position exits.
Their main purpose is simple:
Reduce an existing position.
Prevent accidental position reversals.
Add an extra layer of execution control.
They are especially useful when managing partial exits, take-profit plans, and stop-loss strategies.
Understanding how reduce-only orders work alongside other order types can help traders manage futures positions more precisely and avoid common execution mistakes.
Before using any order feature, traders should review the platform rules, position settings, and market conditions to understand how orders may behave.
A reduce-only order is a futures trading setting that allows an order to only decrease an existing position.
It prevents the order from increasing exposure or opening a position in the opposite direction.
A reduce-only order checks whether an existing position is available to reduce.
If there is no position, or the order would increase exposure, the order will not execute.
Example:
A trader has a 1 BTC long position.
A reduce-only sell order can close that position but cannot create a new short position.
A regular order can open, increase, or close a position depending on its direction and size, while a reduce-only order can only decrease an existing position. A reduce-only order cannot be used to open a new position or increase an existing one, making it useful when the goal is specifically to reduce or close a futures position.
No. The purpose of reduce-only is to prevent new exposure.
If an order would create an opposite position after closing the current position, the exchange will reject or adjust the order based on its execution rules.
Yes. Many traders combine reduce-only with stop-loss orders to ensure an exit order only closes an existing position.
The exact availability depends on the exchange and order settings.
Common reasons include:
No open position exists.
Order size is larger than the current position.
Account position mode does not support the setting.
The order type or trading product has specific restrictions.
No. Reduce-only only controls whether an order can increase exposure.
It does not prevent losses caused by market movements, price volatility, liquidation, or execution conditions.
Trading digital assets involves risk and may result in the loss of capital. Always do your own research. Terms, conditions, and regional restrictions may apply.
