Order Types

XOX provides a comprehensive set of order types for perpetual futures trading, designed for precision, risk management, and optimal execution in a fully decentralized, on-chain environment. The platform supports three core order types: Limit Orders, Market Orders, and Conditional (Trigger) Orders.

1. Limit Order

A limit order enables traders to specify the exact price (or better) at which they are willing to buy or sell a perpetual contract. Buy limit orders execute only at the specified price or lower; sell limit orders execute only at the specified price or higher. This ensures full price control while benefiting from maker rebates when the order adds liquidity.

XOX enhances limit orders with advanced execution options:

• Post-Only: Guarantees the order will only be added to the order book as a maker order. If it would match immediately as a taker, the order is canceled—protecting traders from unintended taker fees and ensuring maximum rebates.

• Reduce-Only: Ensures the order can only reduce an existing position, never increase it or flip direction. This is automatically enforced on leveraged positions to prevent accidental over-exposure.

• Time-in-Force Options:

  • Immediate-or-Cancel (IOC): The order is executed immediately for the available quantity at the limit price or better; any unfilled portion is canceled.

  • Fill-or-Kill (FOK): The entire order must be filled immediately at the limit price or better, otherwise it is fully canceled.

  • Good-Till-Time (GTT): The order remains active until filled or until the specified expiry (maximum 4 weeks).

These options are fully processed on-chain with transparent, verifiable logic, giving traders institutional-grade control in a decentralized setting.

2. Market Order

A market order executes immediately at the best available price from the on-chain order book and liquidity pools. Execution is guaranteed as long as sufficient liquidity exists.

Key characteristics:

• No price specification required—only position side (long/short) and quantity only.

• All market orders are treated as Immediate-or-Cancel and Reduce-Only compatible by default.

• Slippage protection is built in via the XOX price impact and liquidity depth mechanisms, ensuring predictable fills even during volatile periods.

Market orders on XOX benefit from XOX’s deep aggregated liquidity pools and dynamic fee structure that continues to reward liquidity providers in real time.

3. Conditional Orders (Trigger Orders)

Conditional orders combine the power of limit or market orders with a user-defined trigger price. They are ideal for stop-loss, take-profit, or breakout strategies and are executed fully on-chain once triggered.

• Conditional Market Order When the mark price (or last traded price) reaches the trigger price, the order converts to a standard market order and executes immediately. Perfect for stop-loss or aggressive breakout entries.

• Conditional Limit Order Requires both a trigger price and a limit price. When the trigger condition is met, the order is placed on the book as a regular limit order (with optional Post-Only/Reduce-Only flags). This allows precise profit-taking or stop entries with slippage control.

All conditional orders on XOX are stored and monitored on-chain with zero-knowledge settlement layer, ensuring no front-running, full transparency, and guaranteed execution when conditions are met.

By offering this robust, battle-tested suite of order types—identical in functionality to leading centralized perpetual platforms yet fully decentralized—XOX delivers professional trading tools with the security, censorship resistance, and self-custody that users demand.
