type InverseStrategy

InverseStrategy reverses the advice of another strategy. For example, if the original strategy suggests buying an asset, InverseStrategy would recommend selling it.

type InverseStrategy struct {
    // InnerStrategy is the inner strategy.
    InnerStrategy strategy.Strategy
}

func NewInverseStrategy

func NewInverseStrategy(innerStrategy strategy.Strategy) *InverseStrategy

NewInverseStrategy function initializes a new inverse strategy instance.

func (*InverseStrategy) Compute

func (i *InverseStrategy) Compute(snapshots <-chan *asset.Snapshot) <-chan strategy.Action

Compute processes the provided asset snapshots and generates a stream of actionable recommendations.

func (*InverseStrategy) Name

func (i *InverseStrategy) Name() string

Name returns the name of the strategy.

func (*InverseStrategy) Report

func (i *InverseStrategy) Report(c <-chan *asset.Snapshot) *helper.Report

Report processes the provided asset snapshots and generates a report annotated with the recommended actions.

type NoLossStrategy

NoLossStrategy prevents selling an asset at a loss. It modifies the recommendations of another strategy to ensure that the asset is only sold if its value is at or above the original purchase price.

type NoLossStrategy struct {
    // InnertStrategy is the inner strategy.
    InnertStrategy strategy.Strategy
}

func NewNoLossStrategy

func NewNoLossStrategy(innerStrategy strategy.Strategy) *NoLossStrategy

NewNoLossStrategy function initializes a new no loss strategy instance.

func (*NoLossStrategy) Compute

func (n *NoLossStrategy) Compute(snapshots <-chan *asset.Snapshot) <-chan strategy.Action

Compute processes the provided asset snapshots and generates a stream of actionable recommendations.

func (*NoLossStrategy) Name

func (n *NoLossStrategy) Name() string

Name returns the name of the strategy.

func (*NoLossStrategy) Report

func (n *NoLossStrategy) Report(c <-chan *asset.Snapshot) *helper.Report

Report processes the provided asset snapshots and generates a report annotated with the recommended actions.

type StopLossStrategy

StopLossStrategy prevents a loss by recommending a sell action when the assets drop below the given threshold.

type StopLossStrategy struct {
    // InnertStrategy is the inner strategy.
    InnertStrategy strategy.Strategy

    // Percentage is the loss threshold in percentage.
    Percentage float64
}

func NewStopLossStrategy

func NewStopLossStrategy(innerStrategy strategy.Strategy, percentage float64) *StopLossStrategy

NewStopLossStrategy function initializes a new stop loss strategy instance.

func (*StopLossStrategy) Compute

func (s *StopLossStrategy) Compute(snapshots <-chan *asset.Snapshot) <-chan strategy.Action

Compute processes the provided asset snapshots and generates a stream of actionable recommendations.

func (*StopLossStrategy) Name

func (s *StopLossStrategy) Name() string

Name returns the name of the strategy.

func (*StopLossStrategy) Report

func (s *StopLossStrategy) Report(c <-chan *asset.Snapshot) *helper.Report

Report processes the provided asset snapshots and generates a report annotated with the recommended actions.
