SCIFibonacciRetracementAnnotation

@interface SCIFibonacciRetracementAnnotation : SCIMultiPointAnnotationBase

Defines a Fibonacci Retracement annotation, a technical analysis tool placed on the chart using two anchor points which marks the retracement levels between them.

Levels are drawn as horizontal lines with filled regions in between, each labelled with its ratio and the price it corresponds to.

Note

The level lines take their thickness and dash pattern from the inherited stroke, and their colour from regionColors.

levels
Defines the Fibonacci ratios at which levels are drawn.

Note
Defaults to 0, 0.236, 0.382, 0.5, 0.618, 0.786, 1, 1.618, 2.618, 3.618, 4.236.
Declaration
Objective-C

@property (nonatomic, copy) NSArray<NSNumber *> *_Nonnull levels;
Swift

var levels: [NSNumber] { get set }
regionColors
Defines the colours used to fill the regions between levels.

Note
The supplied colours are treated as a ramp and interpolated to thresholds.count - 1 entries, so any number of colours may be provided.
Declaration
Objective-C

@property (nonatomic, copy) NSArray<UIColor *> *_Nonnull regionColors;
Swift

var regionColors: [UIColor] { get set }
fillOpacity
Defines the opacity applied to the filled regions, in the range 0.0 - 1.0.
Declaration
Objective-C

@property (nonatomic) float fillOpacity;
Swift

var fillOpacity: Float { get set }
showConnectorLine
Defines the value indicating whether a connector line is drawn between the two base points.
Declaration
Objective-C

@property (nonatomic) BOOL showConnectorLine;
Swift

var showConnectorLine: Bool { get set }
connectorLineStroke
Defines the SCIPenStyle used to draw the connector line between the two base points.

Note
When nil, a dashed pen in the first region colour is used.
Declaration
Objective-C

@property (nonatomic, strong, nullable) SCIPenStyle *connectorLineStroke;
Swift

var connectorLineStroke: SCIPenStyle? { get set }


                        
                        
                        fibonacciLabelPlacement

Defines where the level labels are placed relative to their level line.

Declaration

Objective-C

@property (nonatomic) SCIFibonacciLabelPlacement fibonacciLabelPlacement;

Swift

var fibonacciLabelPlacement: SCIFibonacciLabelPlacement { get set }


                        
                        
                        fibonacciLabelColorMode

Defines how the level labels are coloured.

Declaration

Objective-C

@property (nonatomic) SCIFibonacciLabelColorMode fibonacciLabelColorMode;

Swift

var fibonacciLabelColorMode: SCIFibonacciLabelColorMode { get set }

labelStyle
Defines the SCIFontStyle used by the level labels.

Note
Its text colour is only used when fibonacciLabelColorMode is SCIFibonacciLabelColorMode_SingleColor; otherwise each label matches its level line.
Declaration
Objective-C

@property (nonatomic, strong) SCIFontStyle *_Nonnull labelStyle;
Swift

var labelStyle: SCIFontStyle { get set }
