用法：通过500次离差相减 表明走势强度
原理：
1、微积分中△y/△x 由于走势中时间变量是常数sum(1,0)
当涉及到△y/△x求导时只涉及到价格这个唯一变量 时间变量被抵消
因此我采用了两两相减求导的方法 可能错误 可能正确 对错他人评
2、从这个角度来看MACD(Moving Average Convergence Divergence)似乎是二阶求导，因此能够拟合走势变化
3、之所以代码中除以2是在于原计算参数太大造成无法正常显示，起调整作用，变量仍是价格
注意：本公式中并不包含未来函数变动
4、虽然引用Refxv这个函数 但最后采用了Ref(x,250)进行抵消
5、两年前的研究成果 现以兹后人
