Record Class Ticker

java.lang.Object
java.lang.Record
com.wualabs.qtsurfer.engine.core.Ticker
public record Ticker(Instrument instrument, BigDecimal bid, BigDecimal bidSize, BigDecimal ask, BigDecimal askSize, BigDecimal open, BigDecimal high, BigDecimal low, BigDecimal last, BigDecimal vwap, BigDecimal volume, BigDecimal quoteVolume, BigDecimal percentageChange, long timestamp) extends Record
Engine-owned, exchange-agnostic ticker. Canonical precision model (BigDecimal) for a point-in-time market snapshot; the primitive-double TickerSnapshot is derived from it for the indicator hot path.

Pure domain record with no XChange dependency. Conversion to/from XChange DTOs lives in the exchange-adapter boundary (XChangeConvert in qtsurfer-engine-exchange), keeping XChange out of engine-core. Fields may be null when the source exchange does not report them.

  • Method Details

    • toString

      public final String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object

    • hashCode

      public final int hashCode()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      Specified by:
      hashCode in class Record
      Returns:
      a hash code value for this object

    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with the compare method from their corresponding wrapper classes.
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
