qmt position对象里面有哪些属性？

查看属性的代码：
 

    obj_list = get_trade_detail_data(ACCOUNT,'stock','position')

    for obj in obj_list:

        print(obj.m_strInstrumentID,obj.m_strInstrumentName,'----')

        # 查看有哪些属性字段

        print('='*10)

        for item in dir(obj):

            if not item.startswith('__'):

                print(item)

                

        print('='*10)
