第四节 震荡指标/PIVOT系统/整数框架(5)
手工计算轴心点数据是非常麻烦的，有些网站提供了相应的计算数据，比如Mataf.net，同时我们也在下面提供了一个在MT4.0上使用比较广泛的轴心点源代码：
#property indicator_chart_window
//#property indicator_separate_window
#property indicator_buffers 7
#property indicator_color1 Orange
#property indicator_color2 DarkBlue
#property indicator_color3 Maroon
#property indicator_color4 DarkBlue
#property indicator_color5 Maroon
#property indicator_color6 Green
#property indicator_color7 Green
//----input parameters
//----buffers

int counted_bars=IndicatorCounted();
int limit,i;
//----indicator calculation
if(counted_bars==0)
{

if(x>240)return (-1);
if (counted_bars<0)return(-1);
//---- last counted bar will be recounted
//if (counted_bars>0)counted_bars--;

for(i=limit;i>=0;i—-)
{
if(High[i+l]>LastHigh) LastHigh=High[i+l];

{
