Example 31 with MockBar

use of org.ta4j.core.mocks.MockBar in project ta4j by ta4j.

the class MMAIndicatorTest method stackOverflowError.

@Test
public void stackOverflowError() throws Exception {
    List<Bar> bigListOfBars = new ArrayList<>();
    for (int i = 0; i < 10000; i++) {
        bigListOfBars.add(new MockBar(i));

    MockTimeSeries bigSeries = new MockTimeSeries(bigListOfBars);
    ClosePriceIndicator closePrice = new ClosePriceIndicator(bigSeries);
    Indicator<Decimal> actualIndicator = getIndicator(closePrice, 10);
    // if a StackOverflowError is thrown here, then the RecursiveCachedIndicator does not work as intended.
