Good After Time Orders
Good After Time (GAT) orders are programmatic trades that remain dormant until their startTime is reached, functioning as scheduled executions with optional price validation.
Core Mechanics
Time-Based Activation
Orders activate only after a specified timestamp and expire at an endTime. The system returns PollTryAtEpoch(startTime) if execution is attempted too early.
Balance Protection
The minSellBalance parameter ensures sufficient token availability, preventing execution after funds have been withdrawn or the order has already filled.
Dynamic Buy Amounts
The off-chain input accepts varying buyAmount values, meaning different buyAmount values create different orderUids, allowing multiple fills of the same order.
Price Validation
Optional Milkman price checkers validate that provided buy amounts meet minimum requirements. The acceptable minimum calculates as:
Where slippage uses basis points (100 bp = 1%).
Key Parameters
Order Structure
The implementation uses GPv2Order.Data structures integrated with ComposableCoW’s programmatic order framework, enabling sophisticated DeFi automation patterns with time-based constraints and price protections.Last modified on March 12, 2026
