How to use

Quick start

final BarSeries barSeries = loadAppleIncSeries(); // create a ta4j bar series
TacChartBuilder.of(barSeries)
        .buildAndShow("AAPL");

Build a chart with custom indicators and a trading record

// 1 Create a barSeries, indicators and run your strategy with ta4j
final BarSeries barSeries = loadAppleIncSeries();
final VolumeIndicator volume = new VolumeIndicator(barSeries);
final ParabolicSarIndicator parabolicSar = new ParabolicSarIndicator(barSeries);
final ClosePriceIndicator closePrice = new ClosePriceIndicator(barSeries);
final EMAIndicator longEma = new EMAIndicator(closePrice, 12);
final EMAIndicator shortEma = new EMAIndicator(closePrice, 4);
final CrossedDownIndicatorRule exit = new CrossedDownIndicatorRule(shortEma, longEma);
final CrossedUpIndicatorRule entry = new CrossedUpIndicatorRule(shortEma, longEma);

final Strategy strategy = new BaseStrategy(entry, exit);
final TradingRecord tradingRecord = new BarSeriesManager(barSeries).run(strategy);

final Returns returns = new Returns(barSeries, tradingRecord, Returns.ReturnType.ARITHMETIC);

// 2 Use the ChartBuilder to create a plot with barSeries, indicators and trading record
TacChartBuilder.of(barSeries)
    .withIndicator(
        of(shortEma)
            .name("Short Ema")
            .color(Color.BLUE)) // default: ChartType.LINE, PlotType.OVERLAY
    .withIndicator(
        of(volume)
            .name("Volume")
            .plotType(PlotType.SUBPLOT)
            .chartType(ChartType.BAR)
            .color(Color.BLUE))
    withIndicator(
        of(parabolicSar)  // default name = toString()
            .plotType(PlotType.OVERLAY)
            .chartType(ChartType.LINE)
            .color(Color.MAGENTA))
    .withIndicator(
        of(longEma)
            .name("Long Ema")
            .plotType(PlotType.SUBPLOT)
            .chartType(ChartType.LINE)) // random color
    .withIndicator(
        of(returns)
            .name("Returns")
            .plotType(PlotType.SUBPLOT)
            .color(Color.BLACK)) // default: ChartType.LINE
    .withTradingRecord(tradingRecord)
    .buildAndShow(); // Creates and displays the JPanel in a JFrame

You can also use a dark theme:

TacChartBuilder.of(barSeries, Theme.DARK).buildAndShow();
