Method Details

clear

public void clear(Instrument instrument)

getFilledBuy

public Optional<ExecutionResult> getFilledBuy(Instrument instrument)

getFailedBuy

public Optional<ExecutionResult> getFailedBuy(Instrument instrument)

getFilledSell

public Optional<ExecutionResult> getFilledSell(Instrument instrument)

getFailedSell

public Optional<ExecutionResult> getFailedSell(Instrument instrument)

getPartialBuys

public List<ExecutionResult> getPartialBuys(Instrument instrument)

getPartialSells

public List<ExecutionResult> getPartialSells(Instrument instrument)

getCompleteAmount

public Optional<Amount> getCompleteAmount(Instrument instrument)

onFilledBuy

public void onFilledBuy(ExecutionResult result)

Records a filled buy execution and emits a chart marker signal (green arrow) for visualization in the trading UI.

Specified by:

onFilledBuy in interface ExecutionCallback

onPartialBuy

public Optional<MarketHintSignal> onPartialBuy(ExecutionResult result)

Specified by:

onPartialBuy in interface ExecutionCallback

onFailedBuy

public Optional<MarketHintSignal> onFailedBuy(ExecutionResult result)

Specified by:

onFailedBuy in interface ExecutionCallback

onFilledSell

public void onFilledSell(ExecutionResult result)

Specified by:

onFilledSell in interface ExecutionCallback

onPartialSell

public Optional<MarketHintSignal> onPartialSell(ExecutionResult result)

Specified by:

onPartialSell in interface ExecutionCallback

onFailedSell

public Optional<MarketHintSignal> onFailedSell(ExecutionResult result)

Specified by:

onFailedSell in interface ExecutionCallback

onComplete

public void onComplete(ExecutionResult enterResult,
 ExecutionResult exitResult,
 Amount yieldAmount)

Handles a completed buy-sell cycle by recording the yield amount and emitting a yield event for downstream consumers (metrics, UI). The emitted yield's output is input + yieldAmount so getYield() agrees EXACTLY with the authoritative amount computed by StrategyExecutorManager.processYield — previously the gross exit traded amount was emitted, so the yield stream disagreed with the accounted PnL whenever fees existed.

Specified by:

onComplete in interface ExecutionCallback

emitSignal

protected void emitSignal(StrategySignal signal)

emitYield

protected void emitYield(StrategyYield yield)

onPositionUpdated

public void onPositionUpdated(PositionSnapshot position)

Specified by:

onPositionUpdated in interface ExecutionCallback

onStopLossPlaced

public void onStopLossPlaced(Instrument instrument,
 String orderId,
 BigDecimal stopPrice)

Description copied from interface: ExecutionCallback

Called when a stop-loss order has been successfully placed on the exchange.

Specified by:

onStopLossPlaced in interface ExecutionCallback

onStopLossTriggered

public void onStopLossTriggered(Instrument instrument,
 ExecutionResult exitResult)

Description copied from interface: ExecutionCallback

Called when a stop-loss order has been triggered (filled) by the exchange.

Specified by:

onStopLossTriggered in interface ExecutionCallback

onStopLossCancelled

public void onStopLossCancelled(Instrument instrument)

Description copied from interface: ExecutionCallback

Called when an active stop-loss order has been cancelled (e.g., before a manual sell).

Specified by:

onStopLossCancelled in interface ExecutionCallback

getStateStore

protected Optional<StateStore> getStateStore(ExecutionResult result)
