    🔄 Changed

    • TotalProfitCriterion: If not NaN the criterion uses the price of the Order and not just the close price of underlying TimeSeries
    • Order: Now constructors and static sell/buyAt(..) functions need a price and amount parameter to satisfy correct be behaviour of criterions (entry/exit prices can differ from corresponding close prices in Order)
