Types

type EMA

type EMA struct {
	// contains filtered or unexported fields
}

EMA is a moving average with exponential decay. It doesn't have any concept of weight so it will only work on homogenous (evenly spaced) time series. ema := NewEMA(0.1818) avg1 = ema.Tick(price1) avg2 = ema.Tick(price2) spike := checkPriceMovingAvg(price, avg, 20%)

func NewEMA

func NewEMA(decay float64) *EMA

NewEMA(decay) returns a new exponential moving average. It weighs new values more than existing values according to the decay. For example: NewEMA(0.05) would give 5% weight to the present and 95% weight to the past. Common to use 2/(selected time period+1).

func (*EMA) Tick

func (ema *EMA) Tick(price *big.Int) *big.Int

func (*EMA) Value

func (ema *EMA) Value() *big.Int

type GasGauge

type GasGauge struct {
	// contains filtered or unexported fields
}

func NewGasGauge

func NewGasGauge(log util.Logger, monitor *ethmonitor.Monitor) (*GasGauge, error)

func (*GasGauge) IsRunning

func (g *GasGauge) IsRunning() bool

func (*GasGauge) Run

func (*GasGauge) SuggestedGasPrice

func (g *GasGauge) SuggestedGasPrice() SuggestedGasPrice

func (*GasGauge) WaitSuggestedGasPrice
