[Git Source](https://github.com/propeller-heads/turbine/blob/90514973167f1eb25cb9eb7756354fb3de34824d/src/settler/structs/Order.sol)

**Title:** Order

A user's intent to trade tokens with price defined as a delta to the mid price.

```solidity
struct Order {
address owner;
address sellToken;
address buyToken;
uint256 sellAmount;
uint256 minBuyAmount;
uint32 maxGas;
uint32 startMidPriceDelta;
uint32 endMidPriceDelta;
uint32 startTime;
uint32 endTime;
uint64 createdTimestamp;
bool partialFill;
bytes callData;
address callDataTarget;
AllowanceParams allowanceParams;
bytes32 salt;
}
```
