What are Bybit's reduce-only orders?

Understanding Reduce-Only Orders on Bybit

Bybit is one of the leading cryptocurrency derivatives exchanges, offering traders a variety of order types to manage risk and optimize their positions. Among these tools, reduce-only orders play a crucial role in position management. These orders are designed specifically to prevent unintended position increases during volatile market conditions.

A reduce-only order can only decrease an existing position or close it entirely. If the order would result in opening a new position or increasing the size of the current one, the system automatically cancels or rejects it. This feature provides traders with greater control, especially when placing stop-losses, take-profits, or trailing stops in fast-moving markets.

How Reduce-Only Orders Function

1. When enabled, the order checks whether executing it would reduce the current position size.
2. If the direction and size of the order align with reducing exposure, the trade proceeds.
3. In cases where the order contradicts the current position—such as buying more in a long position beyond the required amount to close—it gets rejected.
4. The mechanism works for both long and short positions across perpetual and futures contracts.
5. Traders can activate reduce-only status manually when placing limit, market, or conditional orders on Bybit’s interface.

Practical Use Cases for Reduce-Only Settings

1. Setting a stop-loss order without risking accidental leverage increase during sharp price swings.
2. Placing a take-profit level that ensures partial or full exit without adding to the position due to incorrect order direction.
3. Using grid trading bots where each sell (in a long) or buy (in a short) must strictly reduce exposure.
4. Managing large positions where over-leveraging could trigger liquidation if additional margin is consumed unexpectedly.

Risks and Limitations of Reduce-Only Orders

1. Orders may not execute during extreme volatility if they fail the reduction criteria, leaving positions exposed.
2. Users relying solely on reduce-only settings might experience missed exits if prices gap past their levels.
3. On highly illiquid pairs, even valid reduce-only orders might face slippage or partial fills.
4. The feature does not guarantee execution—it only ensures that no new position is opened.
5. Manual monitoring remains essential, as automation tools cannot account for every market anomaly.

Frequently Asked Questions

What happens if a reduce-only order tries to open a new position?The exchange blocks the execution. Bybit’s system validates the order against your current position and rejects any instruction that would increase exposure instead of reducing it.

Can I use reduce-only with leverage adjustments?Yes, but cautiously. Changing leverage doesn’t affect the reduce-only logic directly; however, altering margin levels can influence how close you are to liquidation, making precise order placement even more critical.

Is reduce-only available for spot trading on Bybit?No, this feature applies exclusively to derivative products such as USDT-margined and inverse perpetual contracts, as well as futures. Spot trading does not support reduce-only flags since there are no leveraged positions to manage.

Do reduce-only orders expire?They follow the same lifespan as the order type used. A reduce-only limit order remains active until filled, canceled, or expired based on its time-in-force setting (e.g., Good-Til-Canceled or Immediate-or-Cancel).
