### Question:
CrossedUpIndicatorRule extends AbstractRule { @Override public boolean isSatisfied(int index, TradingRecord tradingRecord) { final boolean satisfied = cross.getValue(index); traceIsSatisfied(index, satisfied); return satisfied; } CrossedUpIndicatorRule(Indicator<Decimal> indicator, Decimal threshold);  CrossedUpIndicatorRule(Indicator<Decimal> first, Indicator<Decimal> second); @Override boolean isSatisfied(int index, TradingRecord tradingRecord);  }### Answer:
@Test public void isSatisfied() { assertFalse(rule.isSatisfied(0)); assertFalse(rule.isSatisfied(1)); assertFalse(rule.isSatisfied(2)); assertTrue(rule.isSatisfied(3)); assertFalse(rule.isSatisfied(4)); assertTrue(rule.isSatisfied(5)); assertFalse(rule.isSatisfied(6)); assertFalse(rule.isSatisfied(7)); }
