Skip to main contentTrade Execution
Onyx Execution Engine (OEE) is designed to minimize slippage and maximize fill rates for large size orders in prediction markets.
Order Types
Onyx supports advanced order types beyond simple swaps:
- Market Orders: Immediate execution at the best available price.
- Limit Orders: Set a specific price (probability) you are willing to buy/sell at. Your order sits in the book until filled.
Smart Routing
When you place a trade, Onyx scans available liquidity sources—central limit order books (CLOB) and AMMs—to find the best execution path.
