回测如何设置手续费和保证金率

可以在Initial函数中通过context的set_commission设置

def initialize(context):
    """初始化"""
    print("initialize")    

    # 股票设置费率的示例
    context.set_commission(equities_commission=PerOrder(buy_cost=0.0003, sell_cost=0.0013, min_cost=5.0))    

    # 期货设置费率的示例
    comm_dict = {
        # 开仓,平仓,平今手续费
        'I':(0.00012, 0.00006, 0.00012),
        'RB':(0.000045, 0.000045, 0.000045)
    }
    context.set_commission(futures_commission=PerContract(comm_dict))

    # 期货设置保证金率
    context.set_margin('RB', 0.05)
