Thanks for the feedback
I looked at the links you sent and after writing a small testbed I found a post similar to mine here

However I cannot match the yield… For the value of yieldFromDirtyPrice I would have expected 1.981424 but I get -0.34982041294362526 instead

Why is the result so OFF the real value? I must be doing something wrong in the code (see below)

CleanPrice=141.505,
coupon=0.0575,
issueDate=1998-02-02,
maturityDate=2029-06-01,
settlementDate=2016-12-06,

dirtyPriceFromCleanPrice: 141.50578767123287
yieldFromDirtyPrice: -0.34982041294362526

	PeriodicSchedule accrualSchedule = PeriodicSchedule
	.builder()
		.startDate(issueDate)
		.endDate(maturityDate)
		.lastRegularEndDate(maturityDate)
		.businessDayAdjustment(businessDayAdj)
		.frequency(Frequency.P6M)
		.stubConvention(StubConvention.SHORT_INITIAL)
		.rollConvention(RollConventions.EOM)
			.build();

	FixedCouponBond fcb = FixedCouponBond
	.builder()
		.accrualSchedule(accrualSchedule)
		.currency(Currency.CAD)
		.securityId(SecurityId.of("CUSIP", "135087WL4"))
		.notional(1000)
		.fixedRate(coupon)
		.dayCount(DayCounts.ACT_365_ACTUAL)
		.yieldConvention(FixedCouponBondYieldConvention.US_STREET)
		.legalEntityId(StandardId.of("LegalEntity", "DUMMY"))
		.settlementDateOffset(DaysAdjustment.ofBusinessDays(3, HolidayCalendarIds.CATO))
			.build();

	ResolvedFixedCouponBond resolvedBond = fcb.resolve(ReferenceData.standard());

		dirty = DiscountingFixedCouponBondProductPricer.DEFAULT.dirtyPriceFromCleanPrice(resolvedBond, settlementDate, initialPrice);
		yield = DiscountingFixedCouponBondProductPricer.DEFAULT.yieldFromDirtyPrice(resolvedBond, settlementDate, dirty);
