Market Orders

Market orders are defined within a transaction and can be uniquely identified by block and event index.

name	type	description
market id	bytes32	The market ID on which the offer is consumed.
taker	address	The consumer address.
got	uint256	The amount of outbound token that the taker received from the market order.
gave	uint256	The amount of inbound token used for the market order.
fee	uint256	The amount of inbound token used to pay the governance fee.
bounty	uint256	The amount of native provisions sent by the expired offers to the taker.
fillVolume	uint256	The original amount asked if fillWants is true, or sent if fillWants is false.
fillWants	bool	Whether the fillVolume is the amount asked or the amount sent.

While indexing, the primary key for a market order should be a composite of the block number and the event index. The following additional metadata should be saved for convenience while querying:

name	type	description
block	uint256	The block number of the transaction.
index	uint256	The index of the event in the transaction.
timestamp	uint256	The timestamp of the transaction.
transaction hash	bytes32	The hash of the transaction.

The following event is emitted by the market order:

/// @notice Emitted when a market order is executed.
event MarketOrder(
  bytes32 indexed market,
  address indexed taker,
  uint256 got,
  uint256 gave,
  uint256 fee,
  uint256 bounty,
  uint256 fillVolume,
  bool fillWants
);
