Example 5: Macaulay Duration

from riskoptima import RiskOptima
cf = RiskOptima.bond_cash_flows_v2(4, 1000, 0.06, 2)  # 2 years, semi-annual, hence 4 periods
md_2 = RiskOptima.macaulay_duration_v3(cf, 0.05, 2)
md_2

ANALYSIS_START_DATE = RiskOptima.get_previous_year_date(RiskOptima.get_previous_working_day(), 1)
ANALYSIS_END_DATE   = RiskOptima.get_previous_working_day()

df_signals, df_exits, returns = RiskOptima.run_index_vol_divergence_signals(start_date=ANALYSIS_START_DATE, 
                                                                            end_date=ANALYSIS_END_DATE)
