当然，上面这个是以价格在均线上下方为条件的，我们也可以以MACD、KDJ、RSI等指标作为均线变色的条件。我们还可以更进一步，把双色线改为三色线等等
===================================================
语句简要解释如下：
===================================================
#property indicator_chart_window
指标放在主图
#property indicator_buffers 2
设置指标线数组为2个
#property indicator_color1 Red
#property indicator_color2 Green
设置第一条指标线颜色值为Red，第二条颜色值为Green
extern int 变色均线=18;
设立一个自定义变量,允许外部值修改,整数形,变量名为"变色均线",默认值18
double duo[];
设立一个自定义数组,双精度型，名称为duo
该数组在后面用于存储红线数据
double kong[];
设立一个自定义数组,双精度型，名称为kong
该数组在后面用于存储绿线数据
int init()
设立初始化函数init。init为系统规定函数名，函数内容自定义。该函数在指标被加载时运行一次
{
SetIndexBuffer(0,duo);
SetIndexBuffer(1,kong);
设置第一、二条指标线的数组为duo和kong
SetIndexStyle(0,DRAW_LINE);
SetIndexStyle(1,DRAW_LINE);
设置第一、二条指标线的样式，线型为连续曲线
SetIndexDrawBegin(0,变色均线);
SetIndexDrawBegin(1,变色均线);
设置第一、二条指标线的最左边的起始划线位置
IndicatorDigits(Digits);
设置指标精确到的小数位数
Digits是当前汇率小数位，日系Digits=2，其他币对Digits=4
return(0);
init函数结束，返回零值
}
int start()
设立触发函数start。start为系统规定函数名，函数内容自定义。当数据变动时，start函数被触发
{
double temp0,temp1;
设立双精度型自定义变量temp0、temp1
int limit;
设立自定义变量limit，整数型
int counted_bars=IndicatorCounted();
设立整数型自定义变量counted_bars，并将IndicatorCounted()的值赋给counted_bars
IndicatorCounted()为缓存数，即已经计算过值的烛柱数
if(counted_bars<0) return(-1);
如果counted_bars值小于零，start函数结束
if(counted_bars>0) counted_bars--;
如果counted_bars值大于零，则counted_bars值减掉1。这是为了配合下一句，以避免limit相差1而出错
limit=Bars-counted_bars;
给limit赋值
Bars为图表中的烛柱数
counted_bars为缓存数，即已经运算过的烛柱数
这样limit的值就是未经运算的烛柱数
这样做的目的是避免重复运算，优化程序
for(int i=limit; i>=0; i--)
循环语句，括号中有三个语句：
第一句int i=limit; 表示循环从i=limit开始
第二句i>=0; 这是循环的条件，如果条件满足则执行大括号中的循环体，如果条件不满足，则中止循环，跳到大括号下面的语句执行
第三句i--，这是循环步调控制语句，每循环一次后执行一次此语句。
i--相当于i=i-1，即i值在原有数值上减少1
{
duo[i]=EMPTY_VALUE;
kong[i]=EMPTY_VALUE;
给数组duo和kong在i位置上赋空值
EMPTY_VALUE：空值
temp0=iMA(NULL,0,变色均线,0,MODE_SMA,PRICE_CLOSE,i);
temp1=iMA(NULL,0,变色均线,0,MODE_SMA,PRICE_CLOSE,i+1);
把均线在i和i+1位置上均线值，分别赋给temp0和temp1
这是为了使后面的语句看起来简洁
if(iClose(NULL,0,i)>=iMA(NULL,0,变色均线,0,MODE_SMA,PRICE_CLOSE,i))
判断条件语句：如果价格高于均线
{duo[i]=temp0; duo[i+1]=temp1;}
判断执行语句：给数组元素duo[i]、duo[i+1]分别赋值
else {kong[i]=temp0; kong[i+1]=temp1;}
如果判断条件不成立，即价格低于均线：则给数组元素kong[i]、kong[i+1]分别赋值
}
return(0);
start函数结束，返回零值
}
