virtual void OnChangeProperty ([CallerMemberName] string propertyName="")

Notifies subscribers when a property value changes.

Properties
virtual bool	AlertsEnabled = false `[get, set]`

bool	FullScreenMode `[get, set]`
	Gets or sets full screen mode for the indicator. Could be applied only to the vertical indicators('IsVerticalIndicator = true')

bool	DenyToChangePanel `[get, set]`
	Gets or sets a value indicating whether changing the indicator's panel is denied. For vertical indicators, it is always denied.

bool	SupportsCalculationTimeFrame `[get, set]`
	Gets or sets a value indicating whether the indicator can be calculated on a timeframe other than the chart's (Indicator.CalculationTimeFrame, PLAT-4527). Off by default: the "Timeframe" parameter is hidden and a timeframe restored from a template is ignored. Set it to `true` in the constructor of an indicator that only needs OHLCV candles of the higher timeframe (moving averages, oscillators, ATR-style ranges). Indicators bound to the chart's bar structure (cluster/footprint, order flow, DOM) must leave it off - the shadow higher-timeframe candles carry no cluster data. A type trait, not a user setting: never persisted.

bool	SupportsCalculationTimeFrameSmoothing `[get, set]`
	Gets or sets a value indicating whether the projected higher-timeframe values may be drawn as a smooth line (Indicator.CalculationTimeFrameSmoothing, PLAT-4527). On by default. Set it to `false` in the constructor of an indicator whose output is a set of levels rather than a curve (trailing stops, support/resistance, square/dot visuals): ramping between two levels draws values the indicator never had. The "Smooth line" parameter is then hidden and ignored. A type trait, not a user setting: never persisted.

bool	DrawAbovePrice `[get, set]`
	Gets or sets a value indicating whether custom painting should be performed on top of rendered bars.

bool	EnableCustomDrawing `[get, protected set]`
	Gets or sets a value indicating whether custom drawing is enabled for the indicator.

bool	IsLoading `[get, set]`
	Indicates that the indicator is still loading its data. While set, the chart indicators legend shows a loading marker next to the indicator name.

bool	ShowDescription `[get, set]`
	Gets or sets a value indicating whether the description of the indicator should be shown.

IIndicatorContainer?	Container `[get, set]`
	Gets or sets the container in which the indicator is hosted.

IIndicatorDataProvider?	DataProvider `[get, set]`
	Gets or sets the data provider for the indicator.

IIndicatorStorage	Storage `[get]`
	Gets path-free storage scoped to this indicator.

List< LineTillTouch >	HorizontalLinesTillTouch `[get]`
	Gets the collection of horizontal lines used to track touch points on the chart.

List< TrendLine >	TrendLines = new() `[get]`
	Gets the collection of trend lines on the chart.

List< DrawingRectangle >	Rectangles = new() `[get]`
	Gets the collection of rectangles on the chart.

SyncDictionary< string, DrawingText >	Labels = new() `[get, set]`
	Gets or sets the collection of named drawing text elements.

IEnumerable< MarketByOrder >	MarketByOrders `[get]`
	Gets a snapshot of the current market by order data.

DateTime	MarketTime `[get]`
	Current market time.

DateTime	UtcTime `[get]`
	Current UTC time.

static ? PerformanceDiagnoser	PerformanceDiagnoser `[get]`
	Indicator performance tracker.

static bool	UseProfiling `[get, set]`
	Set to `true` to measure the performance of all indicators.

IPropertiesEditor?	PropertiesEditor `[get, set]`

string	Name `[get, set]`
	Name of the indicator.

string?	CustomName `[get, set]`
	User-defined display name of this indicator instance. It is independent from other instances of the same indicator type and is used purely as a label. When `null` or empty, the auto-generated name (see ToString) is shown instead.

bool	IsDisposed `[get, set]`
	Gets or sets a value indicating whether the indicator object has been disposed of.

List< IDataSeries >	DataSeries `[get]`
	List of data series used by the indicator.

bool	SupportsExtendedSeries `[get]`
	Gets value indicating whether the data series can be drawn out of chart bars.

List< LineSeries >	LineSeries `[get]`
	List of line series used by the indicator.

string	Panel `[get, set]`
	The name of the panel where the indicator is placed.

bool	IsVerticalIndicator `[get, set]`
	Gets or sets a value indicating whether the indicator is intended to be displayed as a vertical indicator.

bool	UseCandles `[get]`
	Gets a value indicating whether the indicator uses candle data series.

bool	ExternalCalculation `[get, set]`
	When `true` the indicator's own OnCalculate pipeline is suppressed and its data series are filled by an external calculation service (the platform's multi-timeframe projection host, PLAT-4527). The host listens to ExternalCalculateBarRequested / ExternalRecalculateRequested to keep the series in sync. Not persisted; set by the host only.

int	CurrentBar `[get]`
	Bars number. All bars and the values of the corresponding data series have a serial number. The earliest bar of the chart is assigned the number 0; the next bar is assigned the number 1, and so on.

IDataSeries< decimal >?	SourceDataSeries `[get, set]`
	Gets or sets the data series used as the source for the indicator's calculations.

decimal	this[int index] `[get, protected set]`

Property Documentation

◆ AlertsEnabled

virtual bool ATAS.Indicators.ExtendedIndicator.AlertsEnabled = false

getset

◆ Container

IIndicatorContainer? ATAS.Indicators.ExtendedIndicator.Container

getset

Gets or sets the container in which the indicator is hosted.

◆ DataProvider

IIndicatorDataProvider? ATAS.Indicators.ExtendedIndicator.DataProvider

getset

Gets or sets the data provider for the indicator.

◆ DenyToChangePanel

bool ATAS.Indicators.ExtendedIndicator.DenyToChangePanel

getset

Gets or sets a value indicating whether changing the indicator's panel is denied. For vertical indicators, it is always denied.

◆ DrawAbovePrice

bool ATAS.Indicators.ExtendedIndicator.DrawAbovePrice

getset

Gets or sets a value indicating whether custom painting should be performed on top of rendered bars.

◆ EnableCustomDrawing

bool ATAS.Indicators.ExtendedIndicator.EnableCustomDrawing

getprotected set

Gets or sets a value indicating whether custom drawing is enabled for the indicator.

◆ FullScreenMode

bool ATAS.Indicators.ExtendedIndicator.FullScreenMode

getset

Gets or sets full screen mode for the indicator. Could be applied only to the vertical indicators('IsVerticalIndicator = true')

◆ HorizontalLinesTillTouch

List<LineTillTouch> ATAS.Indicators.ExtendedIndicator.HorizontalLinesTillTouch

get

Gets the collection of horizontal lines used to track touch points on the chart.

◆ IsLoading

bool ATAS.Indicators.ExtendedIndicator.IsLoading

getset

Indicates that the indicator is still loading its data. While set, the chart indicators legend shows a loading marker next to the indicator name.

◆ Labels

SyncDictionary<string, DrawingText> ATAS.Indicators.ExtendedIndicator.Labels = new()

getset

Gets or sets the collection of named drawing text elements.

◆ MarketByOrders

IEnumerable<MarketByOrder> ATAS.Indicators.ExtendedIndicator.MarketByOrders

getprotected

Gets a snapshot of the current market by order data.

◆ MarketTime

DateTime ATAS.Indicators.ExtendedIndicator.MarketTime

get

Current market time.

Implements ATAS.Indicators.IMarketTimeProvider.

◆ Rectangles

List<DrawingRectangle> ATAS.Indicators.ExtendedIndicator.Rectangles = new()

get

Gets the collection of rectangles on the chart.

◆ ShowDescription

bool ATAS.Indicators.ExtendedIndicator.ShowDescription

getset

Gets or sets a value indicating whether the description of the indicator should be shown.

◆ Storage

IIndicatorStorage ATAS.Indicators.ExtendedIndicator.Storage

getprotected

Gets path-free storage scoped to this indicator.

◆ SupportsCalculationTimeFrame

bool ATAS.Indicators.ExtendedIndicator.SupportsCalculationTimeFrame

getset

Gets or sets a value indicating whether the indicator can be calculated on a timeframe other than the chart's (Indicator.CalculationTimeFrame, PLAT-4527). Off by default: the "Timeframe" parameter is hidden and a timeframe restored from a template is ignored. Set it to true in the constructor of an indicator that only needs OHLCV candles of the higher timeframe (moving averages, oscillators, ATR-style ranges). Indicators bound to the chart's bar structure (cluster/footprint, order flow, DOM) must leave it off - the shadow higher-timeframe candles carry no cluster data. A type trait, not a user setting: never persisted.

◆ SupportsCalculationTimeFrameSmoothing

bool ATAS.Indicators.ExtendedIndicator.SupportsCalculationTimeFrameSmoothing

getset

Gets or sets a value indicating whether the projected higher-timeframe values may be drawn as a smooth line (Indicator.CalculationTimeFrameSmoothing, PLAT-4527). On by default. Set it to false in the constructor of an indicator whose output is a set of levels rather than a curve (trailing stops, support/resistance, square/dot visuals): ramping between two levels draws values the indicator never had. The "Smooth line" parameter is then hidden and ignored. A type trait, not a user setting: never persisted.

◆ TrendLines

List<TrendLine> ATAS.Indicators.ExtendedIndicator.TrendLines = new()

get

Gets the collection of trend lines on the chart.

◆ UtcTime

DateTime ATAS.Indicators.ExtendedIndicator.UtcTime

get

Current UTC time.

Implements ATAS.Indicators.IMarketTimeProvider.
