Syntax

Copy

public abstract class BaseSimpleIndicator<T> : BaseInstrumentIndicator<T>, 
	ISimpleTradeSignal, ITradeSignal, ISimpleIndicator, IBaseIndicator
where T : new()

Type Parameters

T: Type of indicators value. It must be double if indicator has single return value else it must be Slice with all indicators value. Note: Indicator history store elements of this type. Note: T must has default public constructor.

The BaseSimpleIndicatorT type exposes the following members.

Properties

	Name	Description
	First	Get first(oldest) data element stored in container. Note: if there is not elements in queue it returns DefaltValue. (Inherited from HistoryDataQueueT.)
	FirstDateTime	Get first(oldest) data element DateTime stored in container. Note: if there is not elements in queue it returns DefaltDateTime. (Inherited from HistoryDataQueueT.)
	HistoryCapacity	Set or Get indicator's history capacity. Do not set capacity for indicator if you already add data to it. If indicators HistoryTimeManaged flag is set, this value equal to volume of buffers. If indicators HistoryTimeManaged flag is not set, than indicator store exact HistoryCapacity its values. (Inherited from BaseIndicatorT.)
	HistoryCount	Count of indicators values in indicator history. (Inherited from BaseIndicatorT.)
	HistoryTimeManaged	Indicates whether indicator safe it's history on time period or store specified values count. (Inherited from BaseIndicatorT.)
	HistoryTimePeriod	Set or Get time period, how long indicator save it's value. Do not set history period for indicator if you already add data to it. If you specify indicators HistoryTimePeriod, then indicators HistoryTimeManaged flag will be set. Indicator try to store all of its values on specified HistoryTimePeriod. (Inherited from BaseIndicatorT.)
	IndicatorNeedDateTime	Equal true if user have to specify DateTime in Add method. (Inherited from BaseIndicatorT.)
	ItemDateTime	Return historically latest element with smaller or equal DateTime. Note: do not try to use this method if you didn't specify DateTime to data elements. (Inherited from HistoryDataQueueT.)
	ItemInt32	Get data which was store "index" steps ago. (Inherited from HistoryDataQueueT.)
	Last	Get last data element stored in container. Note: if there is not elements in queue it returns DefaltValue. (Inherited from HistoryDataQueueT.)
	LastDateTime	Get last data element DateTime stored in container. Note: if there is no elements in the queue it returns DefaultDateTime. (Inherited from HistoryDataQueueT.)
	Previous	Get previous data element stored in container. Note: if there is such not elements in queue it returns DefaltValue. (Inherited from HistoryDataQueueT.)
	Ready	Ready flag is set if and only if queue contain something. (Inherited from BaseIndicatorT.)
	ResamplingFactor	Set this parameter if you whant to compress data series. It means that if you set this flag, then indicator will calculate it's values on ResamplingFactor-greater steps. (Inherited from BaseInstrumentIndicatorT.)
	ResamplingMethod	Get or Specify resampling Method. LastElement - mean that we use for calculation values equals to last value on resampling period, ArithmeticMean - mean that we use for calculation values equals to arithmetic mean of values on resampling period, (Inherited from BaseInstrumentIndicatorT.)
	Stable	Flag is set if and only if indicators values is stable. (Inherited from BaseIndicatorT.)
	TradeSignal	Trade signal. (Inherited from BaseInstrumentIndicatorT.)
	TradeSignalType	Characterize indicator trade signal values range and meaning. (Inherited from BaseInstrumentIndicatorT.)
	ValidationStrategy	Indicate what we must do with invalid input values. (Inherited from BaseIndicatorT.)
	Value	Returns value of indicator. For indicators which has more than one value, it returns a slice. (Inherited from BaseIndicatorT.)
	ValueDelayPointPeriod	Set Delay (in points) for indicators Value. (Inherited from BaseIndicatorT.)
	ValueDelayTimePeriod	Set Delay (in timespan) for indicators Value. (Inherited from BaseIndicatorT.)

Methods

	Name	Description
	Add(Double)	Add value to indicator. Note: Do Not use methods with and without DateTime for same instance. Also do not call this method for indicators which need datetime for calculation it's value. To determine do you need to specify DateTime, see IndicatorNeedDateTime flag.
	Add(Double, DateTime)	Add value to indicator. Note: Do Not use methods with and without DateTime for same instance. Note: if you specify time = DefaultTime then method ignore this parameter and call add with out time. To determine do you need to specify DateTime, see IndicatorNeedDateTime flag.
	Clone	Makes full copy of this instance. (Inherited from BaseIndicatorT.)
	CopyTo(Object)	Sets internal state to destination object. (Inherited from BaseIndicatorT.)
	CopyTo(Object, IL_Clone)	Gets internal state from source object. (Inherited from BaseIndicatorT.)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetIndexByTime	Get offset index of element by element time. If there no element with such time, we return latest element with time smaller than specified. If we can't find valid index, we return -1. (Inherited from HistoryDataQueueT.)
	GetTimeByIndex	Return time associated with specified point. (Inherited from HistoryDataQueueT.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	OfflineComputation(Double, T)	Performs offline computation using all data for period simultaneously. In some cases can be faster and/or use less memory than online (step-by-step) computation. Note: Indicator cannot be used before and after calling this method.
	OfflineComputation(Double, DateTime, T)	Performs offline computation using all data for period simultaneously. In some cases can be faster and/or use less memory than online (step-by-step) computation. Note: Indicator cannot be used before and after calling this method.
	SetOnPopDelegate	Set delegate that will be invoked every time a new element is dequeued. (Inherited from HistoryDataQueueT.)
	SetOnPushDelegate	Set delegate that will be invoked every time a new element is enqueued. (Inherited from HistoryDataQueueT.)
	SetQueueListener	Set listener to queue capacity. Queue will call OnPop method every time, when queue drop some element. And OnPush method, when queue store element. Do not use listener with single element queue. Queue support any number of listeners. (Inherited from HistoryDataQueueT.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
