# Trading & Execution

### **How do I view the order book for a pair?**

To view the order book for a venue, select your preferred venue from the list of available venues. The order book will update on the upper right hand side of the screen. You can adjust the depth of the book and tick sizes using the drop down menu on the top left of the order book.

### **What trade types are available on Terrace?**

Terrace supports Limit, Market, and TWAP orders on all venues. In addition, Terrace supports VWAP and conditional orders for pairs with centralized limit orderbooks.

### **How do I cancel a trade?**

Open orders can be cancelled from the Open Orders tab in your Portfolio page, in the Open Orders tab in your Spot page or in History > Orders section. Market orders and swaps execute immediately and cannot be cancelled.

### **Can I modify an order?**

Pending orders can be modified or cancelled from the order management panel as long as they have not been fully filled.

### **Why does my filled price differ from the quoted price?**

Crypto markets move fast. If slippage occurs between the quote and execution, your final fill price may be slightly higher or lower depending on market volatility and liquidity depth.

### **What’s the difference between market and limit orders?**

A market order is an instruction to buy or sell an asset immediately. It guarantees execution but not price and typically fills at or near the current bid or ask. A limit order specifies a price and executes only at that price or better—for example, a buy limit executes at or below the limit price, while a sell limit executes at or above the limit price.

### **Why was only part of my trade filled?**

Partial fills happen when there isn’t enough liquidity at your target price. The remaining portion may still fill, expire, or be cancelled depending on your order type and time-in-force settings.

### **Why did my trade fail?**

Trades can fail due to insufficient balance, high slippage, gas limits being exceeded, or changes in market conditions during execution. If it was a DEX route, MEV protection or pool availability may also be factors. Check the error message for additional details.

### **Which exchanges and liquidity venues does Terrace access?**

Terrace connects to decentralized and centralized exchanges, OTC desks, and market makers - including Binance, Bybit, OKX, Gate, B2C2, Uniswap, Raydium, Jupiter, etc. - giving you broad access to liquidity.

### **Why can't I trade all my tokens?**

On-chain, you can only trade tokens that have settled into your wallet. In off-chain venues (CEX, OTC, and MM), you can trade your entire balance continuously.

### **What is the difference between CeDeFi available to trade and DeFi available to trade?**

Your Defi "available to trade" balance refers to what is currently settled in your wallets (and is thus available to trade instantly). When you place a trade on a DEX, the smart contract pulls tokens directly from your wallet balance. However, it can mean your your balance is fragmented across chains and wallets — not automatically unified. CeDeFi (Centralized-Decentralized Finance) “available to trade” balance reflects tokens settling on centralized exchanges and market makers as well as what is in your wallets. Terrace aggregates all your balances across CEX and DEX, showing total available-to-trade liquidity across sources.
