Understanding Contract Units on OKEx
In financial markets, contract units standardize trading by defining the quantity of an asset per contract. For OKEx futures and perpetual swaps, this concept is expressed through:
- Coin-denominated contracts: Value represents the actual cryptocurrency amount (e.g., 1 BTC contract = 1 Bitcoin).
- Lot-based contracts (张数): Value reflects standardized lots, where each lot equals a fixed USD equivalent (e.g., 1 lot = $100).
This distinction impacts:
- Position sizing precision: Coin units allow micro-adjustments (0.001 BTC), while lots simplify USD-based risk management.
- Liquidity optimization: Smaller units reduce friction for retail traders, lowering transaction costs.
