Types

type State

type State struct {
	Counter int `json:"counter,omitempty"`
}

State is a struct contains the information that we want to keep in the persistence layer, for example, redis or json file.

type Strategy

type Strategy struct {
	Symbol string `json:"symbol"`

	// State is a state of your strategy
	// When BBGO shuts down, everything in the memory will be dropped
	// If you need to store something and restore this information back,
	// Simply define the "persistence" tag
	State *State `persistence:"state"`
}

Strategy is a struct that contains the settings of your strategy. These settings will be loaded from the BBGO YAML config file "bbgo.yaml" automatically.

func (*Strategy) ID

func (s *Strategy) ID() string

ID should return the identity of this strategy

func (*Strategy) InstanceID

func (s *Strategy) InstanceID() string

InstanceID returns the identity of the current instance of this strategy. You may have multiple instance of a strategy, with different symbols and settings. This value will be used for persistence layer to separate the storage.

Run:

redis-cli KEYS "*"

And you will see how this instance ID is used in redis.

func (*Strategy) Run

func (s *Strategy) Run(ctx context.Context, orderExecutor bbgo.OrderExecutor, session *bbgo.ExchangeSession) error

This strategy simply spent all available quote currency to buy the symbol whenever kline gets closed

func (*Strategy) Subscribe

func (s *Strategy) Subscribe(session *bbgo.ExchangeSession)

Subscribe method subscribes specific market data from the given session. Before BBGO is connected to the exchange, we need to collect what we want to subscribe. Here the strategy needs kline data, so it adds the kline subscription.
