 * typically work with {@link FixedCouponBondTrade}. Call
 * {@link FixedCouponBondTrade#resolve(com.opengamma.strata.basics.ReferenceData) FixedCouponBondTrade::resolve(ReferenceData)}
 * to convert {@code FixedCouponBondTrade} to {@code ResolvedFixedCouponBondTrade}.

 * <h4>Price</h4>
 * Strata uses <i>decimal prices</i> for bonds in the trade model, pricers and market data.
 * For example, a price of 99.32% is represented in Strata by 0.9932.
