Constructor Detail

EquityFitDataManager

public EquityFitDataManager(Supplier<T> newEquityFitData,
                            BiConsumer<T,Long> loadFitDataExtraColumns,
                            DynamicTable data)

Create a multithreaded resource to fit a derivative model's parameters for equities.

The input table must have the following columns: - Timestamp: DBDateTime - UnderlyingId: long - UnderlyingSym: String - UnderlyingType: String - UnderlyingBid: double - UnderlyingAsk: double - OptionId: DbLongArray - OptionSym: DbArray - OptionPayoffType: DbArray - OptionExerciseType: DbArray - OptionExpiration: DbArray - OptionStrike: DbDoubleArray - DivExDate: DbArray - DivCashAmount: DbDoubleArray - DivProportionalAmount: DbDoubleArray - YieldCurveDate: DbArray - YieldCurveRate: DbArray - CarryCurveDate: DbArray - CarryCurveRate: DbDoubleArray - CarryCurveError: DbDoubleArray

Parameters:

newEquityFitData - function to create a new EquityFitData of the proper type.

loadFitDataExtraColumns - function to parse the data at a specific table index and load it into the EquityFitData.

data - data for fitting the option model.

Method Detail

table

public DynamicTable table()

Description copied from interface: RowDataManager

Gets the source table.

Specified by:

table in interface RowDataManager<T extends EquityFitData>

Returns:

source table.

newData

public T newData()

Description copied from interface: RowDataManager

Creates a new data instance.

Specified by:

newData in interface RowDataManager<T extends EquityFitData>

Returns:

new data instance.

uniqueIdCurrent

public long uniqueIdCurrent(long index)

Description copied from interface: RowDataManager

Gets the current unique identifier value for a row.

This function should only be called during an update loop or while holding the LTM lock.

Specified by:

uniqueIdCurrent in interface RowDataManager<T extends EquityFitData>

Parameters:

index - table row index.

Returns:

current unique identifier for a row.

uniqueIdPrev

public long uniqueIdPrev(long index)

Description copied from interface: RowDataManager

Gets the previous unique identifier value for a row. One column of each table is designated as a unique identifier for data rows.

This function should only be called during an update loop or while holding the LTM lock.

Specified by:

uniqueIdPrev in interface RowDataManager<T extends EquityFitData>

Parameters:

index - table row index.

Returns:

previous underlying id.

underlyingMidCurrent

public double underlyingMidCurrent(long index)

Gets the current mid market price for the underlying, or NULL if both the bid and ask are not present.

Parameters:

index - data row index.

Returns:

current mid market price for the underlying, or NULL if both the bid and ask are not present.

loadData

public void loadData(T fitData,
                     long index)

Description copied from interface: RowDataManager

Populates a data object with data from a table row.

This method should be called while the LTM lock is held. This can occur either during the update loop or the LTM lock can be acquired outside the update loop. If the LTM lock is not held, the loaded data can be inconsistent or corrupt.

Specified by:

loadData in interface RowDataManager<T extends EquityFitData>

Parameters:

fitData - data structure to populate

index - table index of the row to load data from
