backtestEnabled

public InstrumentMapTickerSourceRTIndicator backtestEnabled(boolean backtestEnabled)

cacheSelector

protected String cacheSelector()

Description copied from class: InstrumentMapRTIndicator

Which field of the incoming data this map extracts for scalar indicators, as a stable string.

Abstract rather than defaulted on purpose: a subclass that reads a different field and forgot to say so would share memoized series between streams that never produced the same numbers, and a compile error is a far better way to find that out than a wrong leaderboard.

Specified by:

cacheSelector in class InstrumentMapRTIndicator

Returns:

the selector name, never null

updateFrom

public void updateFrom(Ticker source)

Propagates a ticker update to all registered indicators and to this map itself. In backtest mode, the ticker's timestamp is used to set a fixed clock on all clock-aware indicators before the update. Each child indicator is updated via RichRTIndicator.updateFrom(T) if it implements that interface, otherwise via TickerSnapshots.update(RTIndicator, MarketSnapshot, TickerValueSource) which extracts the configured value source field.

Specified by:

updateFrom in interface RTIndicatorSource<Ticker>

Parameters:

source - the ticker data to propagate

hashCode

public int hashCode()

Overrides:

hashCode in class InstrumentMapRTIndicator

equals

public boolean equals(Object obj)

Overrides:

equals in class InstrumentMapRTIndicator

getValueSource

public TickerValueSource getValueSource()

isBacktestEnabled

public boolean isBacktestEnabled()

Specified by:

isBacktestEnabled in interface Backtestable

setBacktestEnabled

public void setBacktestEnabled(boolean backtestEnabled)

Specified by:

setBacktestEnabled in interface Backtestable
