Introduction介绍 鉴于许多中国的交易者对交易系统了解不多,本文解释使用MQ4语言编制自动交易系统的基本知识. Title 编制自动交易系统的基本知识 一个交易系统大致包括以下几个方面: 1 开仓策略,即什么条件满足时开仓, 如某条线和某条线上交叉或下交叉, 2 平仓策略,即什么条件满足时平仓, 包括止赢设置,止损设置,和跟踪止赢设置三个方面. 3 资金管理, 其中一个方面就是下单的大小 4 时间管理, 如持仓时间,开平仓时间间隔等 5 账户状态分析,如交易历史,当前资金/仓位/各仓为盈亏状态等. 当然一个交易系统不必包括全部内容,本文做为入门知识也仅通过实例介绍交易系统程序的基本构成.

复制代码Conclusion 结论本例 介绍了自动交易系统程序文件的基本构成, 略加修改就可以用于建立你自己系统. 比如根据你的下单策略修改buyorSell()函数.
注: 本人2006比赛的系统就是这样的框架, 2007 比赛当然也将是这样的框架
