Error with functions using settlement_Date

[mariobajo]

Hi, I get an error with all the fctns that contain settlement_Date as a parameter, for instance bond.yield_to_maturity(settlementDate, cleanPrice).

This is the simple code and the error:

import numpy as np
import matplotlib.pyplot as plt
import datetime as dt

import financepy as fp

from financepy.utils import *
from financepy.products.bonds import *

issueDate = Date(15, 5, 2020)
maturityDate = Date(15, 5, 2035)
coupon = 0.02375
freqType = FrequencyTypes.SEMI_ANNUAL
accrualType = DayCountTypes.ACT_ACT_ICMA
face = 125000

Class bond

bond = Bond(issueDate, maturityDate, coupon, freqType, accrualType, face)

print(bond)

cleanPrice = 99.7808417 # if face is 1 then this must be 0.99780842

settlementDate = Date(15, 5, 2023)
print(bond.bond_payments(settlementDate, face))

#Bond Yield Measures

Current yield is the coupon over the price

current_yield = bond.current_yield(cleanPrice)*100
print("Current Yield %12.7f %%" % (current_yield))

ytm = bond.yield_to_maturity(settlementDate, cleanPrice)
print("Yield to maturity %12.7f %%" % (ytm))

the error:

File ~\AppData\Roaming\Python\Python39\site-packages\financepy\utils\date.py:244 in init
raise FinError("Year cannot be before 1900")

FinError: Year cannot be before 1900

Hi - in the latest release I removed facevalue from the bond constructor - it is no longer a class member but is an additional input when calculating accrued and principal. Because you passed in a face value of 12500, it is using this as the number of ex-div dates and this is why the date error is thrown. Remove facevalue and it should be fine.
