Constructor Detail

PointAndFigureFeedDescriptor

public PointAndFigureFeedDescriptor(Instrument instrument,
                            PriceRange boxSize,
                            ReversalAmount reversalAmount,
                            OfferSide offerSide)

"Fast" constructor, which has minimal set of parameters for FeedDescriptor creation Base period is set to default (one week).

Parameters:

instrument -

boxSize -

reversalAmount -

offerSide -

PointAndFigureFeedDescriptor

public PointAndFigureFeedDescriptor(Instrument instrument,
                            PriceRange boxSize,
                            ReversalAmount reversalAmount,
                            OfferSide offerSide,
                            Period basePeriod)

"Fast" constructor, which has minimal set of parameters for FeedDescriptor creation. The period represents the base period.

Parameters:

instrument -

boxSize -

reversalAmount -

offerSide -

basePeriod - - the period, in which the point and figure bars are calculated. If base period is given Period.INFINITY, then point and figure bars are calculated from the beginning of the history. Everything else at data loading time is considered as a default value (one week), including null.

PointAndFigureFeedDescriptor

public PointAndFigureFeedDescriptor(Instrument instrument,
                            PriceRange boxSize,
                            ReversalAmount reversalAmount,
                            OfferSide offerSide,
                            Period basePeriod,
                            DataInterpolationDescriptor interpolationDescriptor)

Constructor, that sets all required fields.

Parameters:

instrument -

boxSize -

reversalAmount -

offerSide -

basePeriod - - the period, in which the point and figure bars are calculated. If base period is given Period.INFINITY, then point and figure bars are calculated from the beginning of the history. Everything else at data loading time is considered as a default value (one week), including null.

interpolationDescriptor - - tick interpolation descriptor. If null, the DataInterpolationDescriptor.DEFAULT interpolation is used. To get most suitable interpolation descriptor, use DataInterpolationDescriptor.getSuitableDataInterpolationDescriptor(PriceRange priceRange, ReversalAmount reversalAmount) method. To find more about tick interpolation from candles and it's purpose, see DataInterpolationDescriptor.

Method Detail

setPeriod

public void setPeriod(Period period)

Description copied from class: FeedDescriptor

Setter for period. Setter for period. For price aggregation and tick bars (DataType.TICK_BAR, DataType.PRICE_RANGE_AGGREGATION, DataType.RENKO, DataType.POINT_AND_FIGURE, DataType.LINE_BREAK) period works as a base period (more information about base period - IFeedDescriptor.DEFAULT_BASE_PERIOD). Only two base periods are possible - Period.INFINITY and one week (IFeedDescriptor.DEFAULT_BASE_PERIOD). If one provides anything else (including null) than Period.INFINITY, then at data loading time it is considered to be as a default base period (IFeedDescriptor.DEFAULT_BASE_PERIOD).

Specified by:

setPeriod in interface IFeedDescriptor
