在之前的文章中,笔者基本讲诉了所有大多数人认为的有关于交易策略的所有的部分,确实有了交易的设置,入场,离场及交易的机会成本考虑,我们便可以开始用自己找出的策略系统开始交易了。

然而,我们似乎忘记了一个最重要的事情,我们有了交易规则,并且这个规则能导致正值的期望收益,那我们每次该交易多少资本规模呢?

一个有正值的期望收益的系统,肯定不是每笔交易都是盈利的,也一定会有很多的亏损交易,有亏,有赚,最后总体赚钱,在这个长期的过程中,也一定会遇到连续亏损的情况(这很好理解,抛硬币一万次,正反面的概率趋于理论值50%,但是一定会出现连续好几次都是正面或反面的情况 ),在这种连续亏损的情况下,我们的交易规模需要做出何种改变吗?我们初始交易的交易规模定在何种范围是合适的?

笔者相信大多数交易者从未将这种问题的解决方案考虑在自己的交易系统里面,因此很多交易者居然会在亏损甚至在连续亏损的情况下加大交易规模,他们可能是想让亏损的单子摊低价格成本,又或者觉得连续亏损后,下一笔交易的赚钱概率会增大!

这些都是非常糟糕的操作手法,与那些真正做了几十年成功交易的职业玩家所用的资金管理方式大相径庭。科学的资金管理是在有利的时候加大风险暴露,在不利的时候减少风险暴露,简单来说,如果净值在增长,则可以适当增加交易规模,净值在减少,则应该减少交易规模。

这样的资金管理方式可能很多人不以为然,他们还是把预测价格作为自己的首要任务,然而笔者讨论了这么多交易系统的各个部分以及交易者所能做的应对,都是基于一个最基本的信念,即未来是不可以精准预测的,未来充满了各种不确定性,交易游戏不是一个做预言家的游戏。

在此笔者提供一个当年塞克塔提供的简单游戏供大家思考,游戏的规则如下:


规定起始资本规模为1000,每次押注需要选择一个固定百分比作为当前资本的下注比例,
风险回报比为1:2Winning rate50%,
胜负交替发生,最后需要使最后的资本尽量的变多。

大家可以自行模拟演练一下,以此感受一下押注所产生的巨大作用,笔者将在下一期的文章中公布结果。
