交易者的窘境
(本篇阐述的交易者仅为依靠价格本身建立的短期策略)
一 沉默成本
每一个交易策略的生命周期都呈现着前期从思路的启发再到逻辑的推敲直到策略的验证和回测这期间投入了许多的时间金钱,从概率来讲你需要重复很多这样的路径才有可能做出一段时间内持续盈利的策略但前者付出的成本无形中烫平了你后期盈利的收益。
二 不可持续性
经历过策略衰退和失效的兄弟应该会懂得每个策略试错得出的逻辑或规则仅适用于建立的策略这些成果不适用其它或会变成新开发策略时的思维障碍这导致长时间的付出没有积累效应,市场价格现象不断演变进化现阶段盈利的策略就会陷入衰退和最终失效淘汰然而人的创造力会随着年龄的增长或许是因为思维的僵化和惯性等等而衰退这就注定了重复开发策略和成功的概率越发减少慢慢的出现长时间的盈利断层直到无法突破或无法再接受日益增长的付出成本而放弃。
