Features include…

Easy Stock Charting on iOS & Android

Create a financial stock chart on iOS/Android with technical indicators in just 10 lines of code:

// Swift (iOS)
func makeUIView(context: Context) -> SciFinanceChart {
    let chart = SciFinanceChart()
        
    let candleDataProvider = DefaultCandleDataProvider()
    chart.candleDataProvider = candleDataProvider
        
    fillDataProvider(candleDataProvider, with: DataManager.getCandles())
        
    chart.studies.add(PriceSeriesStudy())
    chart.studies.add(RSIStudy(pane: PaneId.uniqueId(name: "RSI")))
        
    chart.isCursorEnabled = true
        
    return chart
}
    
// Kotlin (Android)
override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)

    setContentView(R.layout.activity_main)

    SciChartSurface.setRuntimeLicenseKey("")

    val chart = findViewById(R.id.financeChart)
    val candleDataProvider = DefaultCandleDataProvider()
    chart.candleDataProvider = candleDataProvider
    fillDataProvider(candleDataProvider, DataManager.getCandles())

    chart.studies.add(PriceSeriesStudy(PaneId.DEFAULT_PANE))    
    chart.studies.add(RSIStudy(PaneId.uniqueId("RSI")))
    chart.isCursorEnabled = true
}

This results in the following output:

Built-In Studies (Technical Indicators)

Finance SDK contains 14 built-in studies (technical indicators), available out of the box. There is a special PriceSeriesStudy that displays candlesticks and volume bars. Others represent technical indicators, including:

• ADX Indicator
• Bollinger Bands Indicator
• ATR / Average True Range
• CCI / Commodity Channel Index
• EMA / Exponential Moving Average
• MACD / Moving Average Convergence Divergence
• OBV / On Balance Volume
• RSI / Relative Strength Index
• SMA / Simple Moving Average

… plus many more. It’s also possible to extend the library to add more studies & technical indicators. Take a look at the  IndicatorBase class and how this is used.

Multiple Chart Panes with Pane Resizing

The Finance.iOS and Finance.Android stock chart library also supports multiple panes for technical indicators. Panes can be resized by tapping and dragging the chart surface.

Cursors, Legends, Zooming, Panning

Our financial library is built for interactivity. Built-in, you will find rich zooming and panning. You can drag an axis to scale the axis, tap to pan, pinch to zoom and add or remove a cursor to the chart.

Watch the video below for a demo of the zooming and panning interactions on an iOS chart.

Data Provider & Data Manager

One of the most challenging aspects of building an Android or iOS stock chart app is handling data—whether that’s the updates or properties. Everything in the Finance.iOS and Finance.Android library is reactive, meaning if you change the input data, all technical indicators automatically update. If you change a property on an indicator or study, the chart will automatically update as well.

There’s a detailed description in the Finance.iOS Readme and Finance.Android Readme showing what the DataManager is and how it works.
