    你会持仓多久?是几分钟,几小时,还是一天内平仓呢?


    持仓多久,多因人而异。让我们单从交易成本分析一下,多久交易频率才是做划算。


    从交易成本来算

    最高的交易频率是一分钟,如果以一分钟作为交易区间,大约每隔十分钟完成一笔交易,每一笔交易的价格变动区间最多在十点或十五点,扣去三点的点差,最完美的操作,每笔交易点差部份已占三分之一,从风险和报酬的观点上来说,摩擦损失实其实甚高,所赚得的都必须一半分享和交易商分享,其实并不划算。

    较低一点的交易频率是五分钟,大约每小时交易一次,估计这其间价格波幅有40点,扣去五点点差,最完美的操作,每笔交易点差占据利润的1/10,甚至更多,从风险和报酬的观点上来说,其实也并不划算。

    再低一点的交易频率是60分钟,这样的话大约每10小时交易一次,估计每个升降幅度各有80点,扣去五点点差,最完美的操作,每笔交易点差占据利润的 6%,合理与否,看个人观点。但对于只能下班之后看盘的人,使用60分钟作为交易区间的话,常常无法当日平仓,也不能留仓过夜,容易陷入进退两难的困境。

    再低一点的交易频率是日计,大约每10日交易一次,估计每个升降幅度各有400点,扣去五点点差,最完美的操作,每笔交易点差占据利润的1.25%。这是一个很理想的百分比,而且每一格交易循环长达十日,适合专业或业余的交易人,不紧迫看盘,压力较轻。

    那是否说明交易频率越低越好呢?那却不一定。如果交易频率以周或是月算的话,这样相隔的交易时间太长,过长的等待可能干扰交易人的判断,过长的交易时间会忽略中期的走势,反而丧失理想的交易机会,而且需要很大的交易保证金,所以也不是理想的交易频率。

    从俺多次爆仓的体会来说,最好不要刻意为做单而做,主要是要学会等待,有机会就做,没机会就不做,宁肯错过,也别做错。频率太频繁确实不好,我好多次就是超短线,折腾来折腾去,死掉了。

    都长时间交易有时是看你手中的资金大小,小的一般交易时间普遍偏短,25刀只能经历25点风险(实际是不到23点)这种情况下有微小的盈利就都跑了,以后随着资金的增长抗风险的能力加强,不赚100点我认头陪50点这样持仓时间就长了。

    楼主的出发点是点差成本计算
    而你的出发点是没有考虑这个交易成本的

    这也就是说重仓适合短线了哦?
