怎样建立自己的交易系统之三：
我历来反对有人说“会买是徒弟，会卖是师傅。”这纯粹是本末倒置信口开河、绝对的大忽悠。你连在哪买的大门都找不到，何谈“会卖的是师傅。”？！
只要学会买，你可以在拉升中的任何时间卖出都可以，只是赚多赚少问题！
这次经过进一步修改调整，这次把A15D做的更完美。A15D下插线在原基础上不仅做成下插后不仅变红，更重要的是当主图K线在下跌临近坑底时，由蓝色变成红色。当股价拉升接近顶部时，该线由红色变成蓝色。
低位蓝色和高位蓝色都是转折预警信号。
我喜欢追求完美。尽管为了这条变色线彻夜未眠，成功的结果让我喜出望外。
我敢说像这样在一条线上出现三种颜色，并赋予新的、明确的市场操作指导意义，不管是买卖股票、还是做多做空期货都是极少见的优秀指标信号。自认为是我所有修改过的源码中的最精华之笔！
