ef
This function plots random portfolios based on their risk and returns and shows the efficient frontier.

| random_seed | Seed used to generate random portfolios | 123 | True | None |
| tangency | Adds the optimal line with the risk-free asset | False | True | None |
| plot_tickers | Whether or not to plot the tickers for the assets provided | True | True | None |
| risk_measure | Risk measure used to optimize the portfolio. Possible values are: 'MV' : Variance 'MAD' : Mean Absolute Deviation 'MSV' : Semi Variance (Variance of negative returns) 'FLPM' : First Lower Partial Moment 'SLPM' : Second Lower Partial Moment 'CVaR' : Conditional Value at Risk 'EVaR' : Entropic Value at Risk 'WR' : Worst Realization 'ADD' : Average Drawdown of uncompounded returns 'UCI' : Ulcer Index of uncompounded returns 'CDaR' : Conditional Drawdown at Risk of uncompounded returns 'EDaR' : Entropic Drawdown at Risk of uncompounded returns 'MDD' : Maximum Drawdown of uncompounded returns | MV | True | MV, MAD, MSV, FLPM, SLPM, CVaR, EVaR, WR, ADD, UCI, CDaR, EDaR, MDD |
| nan_fill_method | Method used to fill nan values in time series, by default time. Possible values are: 'linear': linear interpolation 'time': linear interpolation based on time index 'nearest': use nearest value to replace nan values 'zero': spline of zeroth order 'slinear': spline of first order 'quadratic': spline of second order 'cubic': spline of third order 'barycentric': builds a polynomial that pass for all points | time | True | linear, time, nearest, zero, slinear, quadratic, cubic, barycentric |
| historic_period | Period to get yfinance data from. Possible frequency strings are: 'd': means days, for example '252d' means 252 days 'w': means weeks, for example '52w' means 52 weeks 'mo': means months, for example '12mo' means 12 months 'y': means years, for example '1y' means 1 year 'ytd': downloads data from beginning of year to today 'max': downloads all data available for each asset | 3y | True | 1d, 5d, 1mo, 3mo, 6mo, 1y, 2y, 5y, 10y, ytd, max |

| end_period | End date to get yfinance data from. Must be in 'YYYY-MM-DD' format | True | None | |
| log_returns | If use logarithmic or arithmetic returns to calculate returns | False | True | None |
| return_frequency | Frequency used to calculate returns. Possible values are: 'd': for daily returns 'w': for weekly returns 'm': for monthly returns | d | True | d, w, m |
| max_nan | Max percentage of nan values accepted per asset to be considered in the optimization process | 0.05 | True | None |
| threshold_value | Value used to replace outliers that are higher to threshold in absolute value | 0.3 | True | None |
| risk_free | Risk-free rate of borrowing/lending. The period of the risk-free rate must be annual | 0.02924 | True | None |
| significance_level | Significance level of CVaR, EVaR, CDaR and EDaR | 0.05 | True | None |
| long_allocation | Amount to allocate to portfolio | 1 | True | None |
