Types ¶
type DynamicAmpSpread ¶
type DynamicAmpSpread struct {
types.IntervalWindow
// AskSpreadScale is used to define the ask spread range with the given percentage.
AskSpreadScale *bbgo.PercentageScale `json:"askSpreadScale"`
// BidSpreadScale is used to define the bid spread range with the given percentage.
BidSpreadScale *bbgo.PercentageScale `json:"bidSpreadScale"`
// contains filtered or unexported fields
}
DynamicSpreadAmp uses kline amplitude to calculate spreads
type DynamicExposure ¶
type DynamicExposure struct {
// BollBandExposure calculates the max exposure with the Bollinger Band
BollBandExposure *DynamicExposureBollBand `json:"bollBandExposure"`
}
func (*DynamicExposure) GetMaxExposure ¶
func (d *DynamicExposure) GetMaxExposure(price float64, trend types.Direction) (maxExposure fixedpoint.Value, err error)
GetMaxExposure returns the max exposure
func (*DynamicExposure) Initialize ¶
func (d *DynamicExposure) Initialize(symbol string, session *bbgo.ExchangeSession)
Initialize dynamic exposure
func (*DynamicExposure) IsEnabled ¶
func (d *DynamicExposure) IsEnabled() bool
type DynamicExposureBollBand ¶
type DynamicExposureBollBand struct {
// DynamicExposureBollBandScale is used to define the exposure range with the given percentage.
DynamicExposureBollBandScale *bbgo.PercentageScale `json:"dynamicExposurePositionScale"`
types.IntervalWindowBandWidth
// contains filtered or unexported fields
}
DynamicExposureBollBand calculates the max exposure with the Bollinger Band
type DynamicQuantity ¶
type DynamicQuantity struct {
// LinRegQty calculates quantity based on LinReg slope

Initialize dynamic quantity
func (*DynamicQuantity) IsEnabled ¶
func (d *DynamicQuantity) IsEnabled() bool
type DynamicQuantityLinReg ¶
type DynamicQuantityLinReg struct {
// DynamicQuantityLinRegScale is used to define the quantity range with the given parameters.
DynamicQuantityLinRegScale *bbgo.PercentageScale `json:"dynamicQuantityLinRegScale"`
// QuantityLinReg to define the interval and window of the LinReg
QuantityLinReg *indicator.LinReg `json:"quantityLinReg"`
}
DynamicQuantityLinReg uses LinReg slope to calculate quantity
type DynamicQuantitySet ¶

type DynamicSpread ¶
type DynamicSpread struct {
// AmpSpread calculates spreads based on kline amplitude
AmpSpread *DynamicAmpSpread `json:"amplitude"`
// WeightedBollWidthRatioSpread calculates spreads based on two Bollinger Bands
WeightedBollWidthRatioSpread *DynamicSpreadBollWidthRatio `json:"weightedBollWidth"`
}
func (*DynamicSpread) GetAskSpread ¶
func (ds *DynamicSpread) GetAskSpread() (askSpread float64, err error)
GetAskSpread returns current ask spread
func (*DynamicSpread) GetBidSpread ¶
func (ds *DynamicSpread) GetBidSpread() (bidSpread float64, err error)
GetBidSpread returns current dynamic bid spread
func (*DynamicSpread) Initialize ¶

type DynamicSpreadBollWidthRatio ¶
type DynamicSpreadBollWidthRatio struct {
// AskSpreadScale is used to define the ask spread range with the given percentage.
AskSpreadScale *bbgo.PercentageScale `json:"askSpreadScale"`
// BidSpreadScale is used to define the bid spread range with the given percentage.
BidSpreadScale *bbgo.PercentageScale `json:"bidSpreadScale"`
// Sensitivity factor of the weighting function: 1 / (1 + exp(-(x - mid) * sensitivity / width))
// A positive number. The greater factor, the sharper weighting function. Default set to 1.0 .
Sensitivity float64 `json:"sensitivity"`
DefaultBollinger types.IntervalWindowBandWidth `json:"defaultBollinger"`
NeutralBollinger types.IntervalWindowBandWidth `json:"neutralBollinger"`
// contains filtered or unexported fields
