Counterparty Price, Bid 1 Price, and Ask 1 Price in Perpetual Contracts
In cryptocurrency perpetual contract trading, understanding the price terminology on the order book is crucial for effective trade execution. Among these, counterparty price, Bid 1 price, and Ask 1 price are concepts frequently encountered by traders in their daily operations.
Counterparty Price
Counterparty price is an order type designed to ensure immediate execution. When a trader selects counterparty price for an order, the system automatically places a limit order at the current best counterparty price in the order book:
- Buy to Open Long: If you choose counterparty price to buy to open long, the system will submit a limit order at the lowest "Ask 1 price" in the current order book. This means the trader is willing to accept the best price currently offered by the sellers.
- Sell to Open Short: If you choose counterparty price to sell to open short, the system will submit a limit order at the highest "Bid 1 price" in the current order book. This means the trader is willing to accept the best price currently offered by the buyers.
The advantage of using counterparty price is fast execution, especially suitable for trading strategies that are less price-sensitive and more focused on timely entry.
Bid 1 Price
Bid 1 price refers to the highest current bid price in the order book. It represents the maximum price buyers in the market are willing to pay. On the buy side of the order book, Bid 1 price is the closest bid order price to the current market price, with typically lower bid orders above it.
Ask 1 Price
Ask 1 price refers to the lowest current ask price in the order book. It represents the minimum price sellers in the market are willing to accept. On the sell side of the order book, Ask 1 price is the closest ask order price to the current market price, with typically higher ask orders below it.
Related Concepts: Bid-Ask Spread and Order Book
- Bid-Ask Spread: The difference between the Bid 1 price and the Ask 1 price, reflecting the market's liquidity cost. A smaller spread generally indicates better market liquidity and lower trading costs.
- Order Book: A real-time list displaying all buy and sell orders, including the quantity of pending orders at different price levels (depth) and the total quantity of pending orders (liquidity), which is a direct reflection of market supply and demand.
What is "One Lot" in Perpetual Contracts?
In perpetual contract trading, "one lot" is a common expression, but it is not a fixed unit. Instead, it refers to the "contract face value" or "minimum order size" of the contract. This unit varies depending on the cryptocurrency exchange and the specific contract product.
Definition of Contract Face Value
The contract face value determines the quantity or value of the underlying asset represented by each contract. Traders need to clarify this specific provision of the contract they are trading when calculating position sizes.
Examples of Different Platforms and Contract Types
Below are some common settings for "one lot" or minimum trading unit in perpetual contracts on major exchanges. Please note that these values may change with market conditions and platform policies, so always check the latest official contract details before trading:
- OKX (OKX):
- Coin-margined perpetual contracts: For example, for a BTC coin-margined contract, each contract might represent $100 worth of Bitcoin. This means if the Bitcoin price is $70,000, one contract represents approximately 100/70000 BTC.
- USDT-margined perpetual contracts: For example, for a BTCUSDT contract, each contract might represent 0.01 BTC. This means trading 100 contracts is equivalent to trading 1 Bitcoin.
- USD-margined perpetual contracts: For example, for a SOLUSD UM contract, each contract might represent 0.01 SOL.
- Binance (Binance): Binance's USDⓈ-M perpetual contracts also adjust their minimum trading unit and price precision based on market conditions. For example, the minimum order size for some contracts might be set to 0.001 units of the underlying asset.
- Other Platforms: Many exchanges such as Kraken, Gate, etc., explicitly list the contract face value or minimum trading unit for each perpetual contract in their contract rules. Traders should carefully read the relevant instructions before opening a position.
Therefore, there is no single answer when asking "what is one lot in perpetual contracts." Traders must refer to the contract face value or minimum trading size based on the exchange and specific contract product they choose (e.g., BTCUSDT perpetual contract, ETHUSD perpetual contract, etc.). Understanding these details is crucial for accurately calculating margin, profit/loss, and managing risk.
