Provides a method (discrete_allocation) that can be converted into an actual allocation available for purchase by entering the latest price and desired portfolio size ($ 10,000 in this example)

from portfolio_backtest import Backtest
bt = Backtest(
    tickers={
        "VTI": 0.6,
        "AGG": 0.25,
        "GLD": 0.15,
    }
)
print(bt.discrete_allocation(total_portfolio_value=10000))

{'Discrete allocation': {'VTI': 28, 'AGG': 21, 'GLD': 9}, 'Funds remaining': '$109.45'}
