Types

type Client 

type Client struct {
	Requests     chan *types.WebsocketMessage
	Responses    chan *types.WebsocketMessage
	Logs         chan *ClientLogMessage
	Wallet       *types.Wallet
	RequestLogs  []types.WebsocketMessage
	ResponseLogs []types.WebsocketMessage

	NonceGenerator *rand.Rand
	// contains filtered or unexported fields
}

Client simulates the client websocket handler that will be used to perform trading. requests and responses are respectively the outbound and incoming messages. requestLogs and responseLogs are arrays of messages that denote the history of received messages wallet is the ethereum account used for orders and trades. mutex is used to prevent concurrent writes on the websocket connection

func NewClient 

func NewClient(w *types.Wallet, s Server) *Client

NewClient a default client struct connected to the given server

func (*Client) SetNonce 

func (c *Client) SetNonce(o *types.Order)

func (*Client) Start 

func (c *Client) Start()

start listening and handling incoming messages

type ClientLogMessage 

type ClientLogMessage struct {
	MessageType string         `json:"messageType"`
	Orders      []*types.Order `json:"order"`
	Trades      []*types.Trade `json:"trade"`
	Matches     *types.Matches `json:"matches"`
	Tx          *common.Hash   `json:"tx"`
	ErrorID     int8           `json:"errorID"`
}

The client log is mostly used for testing. It optionally takes orders, trade, error ids and transaction hashes. All these parameters are optional in order to allow the client log message to take in a lot of different types of messages An error id of -1 means that there was no error.

	Pair           *types.Pair
	Params         *OrderParams
	OrderNonce     uint64
	NonceGenerator *rand.Rand
}

Orderfactory simplifies creating orders, trades and cancelOrders objects Pair is the token pair for which the order is created Exchange is the Ethereum address of the exchange smart contract CurrentOrderID increments for each new order

func NewOrderFactory 

func NewOrderFactory(p *types.Pair, w *types.Wallet, exchangeAddress common.Address) (*OrderFactory, error)

NewOrderFactory returns an order factory from a given token pair and a given wallet TODO: Refactor this function to send back an error

func (*OrderFactory) GetAddress 

func (f *OrderFactory) GetAddress() common.Address

GetAddress returns the order factory address

func (*OrderFactory) GetExchangeAddress 

func (f *OrderFactory) GetExchangeAddress() common.Address

func (*OrderFactory) GetWallet 

func (f *OrderFactory) GetWallet() *types.Wallet

GetWallet returns the order factory wallet

func (*OrderFactory) NewBuyOrder 

func (f *OrderFactory) NewBuyOrder(pricepoint int64, value float64, filled ...float64) (types.Order, error)

NewBuyOrder creates a new buy order from the order factory

func (*OrderFactory) NewBuyOrderMessage 

func (f *OrderFactory) NewBuyOrderMessage(price int64, amount float64) (*types.WebsocketMessage, *types.Order, error)

func (*OrderFactory) NewCancelOrder 

func (f *OrderFactory) NewCancelOrder(o *types.Order) (*types.OrderCancel, error)

func (*OrderFactory) NewCancelOrderMessage 

func (f *OrderFactory) NewCancelOrderMessage(o *types.Order) (*types.WebsocketMessage, *types.OrderCancel, error)

func (*OrderFactory) NewLargeOrder 

func (f *OrderFactory) NewLargeOrder(baseToken common.Address, quoteToken common.Address, amount *big.Int, pricepoint *big.Int) (*types.Order, error)

func (*OrderFactory) NewOrder 

func (f *OrderFactory) NewOrder(baseToken common.Address, quoteToken common.Address, amount int64, pricepoint int64) (*types.Order, error)

NewOrder returns a new order with the given params. The order is signed by the factory wallet. Currently the nonce is chosen randomly which will be changed in the future

func (*OrderFactory) NewOrderMessage 

func (f *OrderFactory) NewOrderMessage(baseToken, quoteToken common.Address, amount, pricepoint int64) (*types.WebsocketMessage, *types.Order, error)

NewOrderMessage creates an order with the given params and returns a new PLACE_ORDER message

func (*OrderFactory) NewSellOrder 

func (f *OrderFactory) NewSellOrder(pricepoint int64, value float64, filled ...float64) (types.Order, error)

NewBuyOrder returns a new order with the given params. The order is signed by the factory wallet NewBuyOrder computes the AmountBuy and AmountSell parameters from the given amount and price. Currently, the amount, price and order type are also kept. This could be amended in the future (meaning we would let the engine compute OrderBuy, Amount and Price. Ultimately this does not really matter except maybe for convenience/readability purposes)

func (*OrderFactory) NewSellOrderMessage 

func (f *OrderFactory) NewSellOrderMessage(price int64, amount float64) (*types.WebsocketMessage, *types.Order, error)

func (*OrderFactory) NewTrade 

func (f *OrderFactory) NewTrade(o *types.Order, amount int64) (types.Trade, error)

NewTrade returns a new trade with the given params. The trade is signed by the factory wallet. Currently the nonce is chosen randomly which will be changed in the future

func (*OrderFactory) SetExchangeAddress 

func (f *OrderFactory) SetExchangeAddress(addr common.Address) error

SetExchangeAddress changes the default exchange address for orders created by this factory

type OrderParams 

type OrderParams struct {
	ExchangeAddress common.Address
	MakeFee         *big.Int
	TakeFee         *big.Int
	Nonce           *big.Int
}

OrderParams groups FeeMake, FeeTake, Nonce, Exipres FeeMake and FeeTake are the default fees imposed on makers and takers Nonce is the ethereum account nonce that tracks the numbers of transactions for the order factory account
