# Spot Trading Rules

To ensure a safe, transparent, and efficient trading experience on YUBIT, the following rules apply to all spot trading activities. Please read them carefully before trading.

***

### **Trading Pairs & Trading Hours**

  YUBIT offers spot trading for major cryptocurrencies such as BTC and ETH, as well as a variety of innovative assets.

* **Trading Hours:** 24/7 (excluding scheduled system maintenance)
* If a trading pair is delisted due to market or project reasons, an announcement will be made in advance.

***

### **Order Types**

  YUBIT supports multiple order types to meet different trading needs:

#### **Market Order**

* Executes immediately at the current market price.
* Ideal for users who prioritize fast execution.
* The final execution price may differ due to market volatility.

#### **Limit Order**

* Executes only when the market reaches the user-defined price.
* Unfilled limit orders remain in the order book and can be canceled at any time.

***

### **Trading Fees**

  Spot trading fees are divided into **Maker (limit orders added to the order book)** and **Taker (orders that take liquidity)**.

* Fee rates vary based on your **VIP level**.
* Please refer to the **Fee Schedule** or **VIP Program** page for the latest fee information.

***

**Trading Limits & Minimum Order Size**

  Each trading pair has specific rules, such as:

* Minimum order quantity
* Minimum order value
* Minimum order increment

  Orders below the minimum requirement cannot be submitted.

***

### **Order Matching & Execution**

  Orders are matched based on **price priority** and **time priority**:

* Orders with better prices are executed first.
* If prices are the same, earlier orders are executed first.
* Partially filled orders will remain in the order book until fully executed or canceled.

***

### **Order Cancellation Rules**

* **Limit Orders:** Can be canceled at any time before execution.
* **Market Orders:** Cannot be canceled once submitted, as they enter the matching engine immediately.
* In special situations (e.g., extreme volatility), some orders may be rejected due to system protection mechanisms.

***

### **Risk Warning**

* Cryptocurrencies are high-risk assets and may experience significant price fluctuations.
* Market orders may incur slippage when market depth is insufficient.
* Please safeguard your account credentials to prevent unauthorized access.

***

### **Abnormal Activity Handling**

  The platform reserves the right to intervene in the following situations:

* Orders placed at abnormal prices
* System errors leading to abnormal trades
* Market manipulation, wash trading, or malicious behavior

  Actions may include order cancellation, asset freezing, or other risk-control measures.
