Classes
class	BaseDataSeries
	Base generic data series class providing common functionality. More...

class	BaseIndicator
	Base class for custom indicators in a chart. More...

class	Candle
	Represents a candle in trading, which includes open, high, low, and close prices. More...

class	CandleDataSeries
	Represents a data series of candles. Each element in the series is a Candle. More...

class	CandlePartSeries
	Represents a data series of decimal values derived from specific parts of an IndicatorCandle created by an ICandleCreator. More...

struct	CandleSeriesInstrument
	Identifies an instrument for a candle series request. Provide any one of the keys; they are tried most-specific first: ContractId, SecurityId, Code + Exchange, then Code alone. A plain string converts implicitly to a code-only descriptor. More...

class	CandleSeriesRequest
	Describes a candle series to request: the timeframe and, optionally, another instrument. More...

struct	CandleSeriesTimeFrame
	A candle series timeframe: aggregation type plus its numeric parameter (minutes, seconds, ticks, lots or price-range ticks depending on the type). Create instances via the factory methods. More...

class	CandleSeriesTimeFrameJsonConverter
	Round-trips CandleSeriesTimeFrame as a compact "PeriodType:Value" string (e.g. "Minutes:5"). The struct exposes only factory methods and a private constructor, so default Newtonsoft handling (parameter-name matching) would be fragile across refactorings; templates persist these values. Reading tolerates the legacy object form and returns the default (unset) value for anything unparsable. More...

class	ChartObject
	Base class for objects in a chart. More...

class	Container
	Represents a container with a defined region on the chart. More...

	Represents a custom value with associated properties. More...

class	CustomValueDataSeries
	Represents a custom data series that holds CustomValue objects. More...

class	DataSeriesTypeConverter

class	ExoticCandleSeriesTimeFrame
	An exotic candle series timeframe. Create instances via the factory methods. Kept separate from CandleSeriesTimeFrame: these types carry extra parameters, and the common struct stays two-field forever. More...

class	ExoticCandleSeriesTimeFrameJsonConverter
	Round-trips ExoticCandleSeriesTimeFrame as a compact "Kind:Value[:Value...]" string (e.g. "RangeUS:4:2:2"). More...

class	ExtendedIndicator
	An extended base class for custom indicators that provide additional functionality for drawing, alerts, market data handling, etc. More...

class	Extensions
	Contains extension methods for various types.

class	FavoriteByDefaultAttribute
	Adds the indicator to the user's favorites once, when it first appears in the indicators catalog. Honored only for indicators the platform installed as personal-account modules; any other custom indicator ignores it. Each indicator is seeded at most one time, so a user who removes the star afterwards is not overridden on later launches. More...

class	MtfCalculationHost
	PLAT-4527: computes an indicator on a different timeframe and projects the values onto the chart bars as steps. Owned by the visible Indicator (V): a hidden shadow clone of V calculates on the MTF candle series (obtained through V's ICandlesDataProvider); this host copies the shadow's output series into V's series. V itself runs in BaseIndicator.ExternalCalculation mode. Semantics: historical chart bars take the value of the last CLOSED MTF candle (no lookahead); the last chart bar tracks the forming MTF candle until it closes. The projection is deterministic, so live values match a post-reload chart exactly.
