What's in Finance.iOS and Finance.Android?
Finance Charts SDK adds professional-grade financial & stock charting capabilities for native iOS & Android apps.
It is built on top of the SciChart – an award-winning, high-performance chart library for iOS, Android, Windows, and JavaScript apps.
Features include...
Easy Financial / 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 & dragging the chart surface.
Cursors, Legends, Zooming, Panning, Pinch zooming
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. Add or remove a cursor to the chart.
Data Provider and Data Manager
One of the most challenging aspects of building a stock chart app on iOS or Android is handling data, updates of data and properties. Everything in the Finance.iOS and Finance.Android library is reactive, meaning if change the input data, all technical indicators automatically update. If you change a property on an indicator/study then the chart will automatically update as well.
There's a detailed description in the Finance.iOS readme and Finance.Android readme showing what DataManager is and how it works.
