求教解释股票公式ABS(ma(c,20)-ma(c,90))/ma(c,60);

1. 求教解释股票公式ABS(ma(c,20)-ma(c,90))/ma(c,60);

朋友，不是除以60，而是除以60天的均线。
其中：MA表示均价，ma(c,60)就是60天收盘的平均价格了。
          ABS表示绝对值。

2. ABS(MA(C,20)-MA(C,90))是怎样进行选股，是怎样在通信达软件里面自动选股？

源码的意义：收盘价的20日简单移动平均-收盘价的90日简单移动平均的绝对值。
收盘价的20日简单移动平均为短期慢线，收盘价的90日简单移动平均为中期慢线。短期慢线大于中期慢线，多头趋势；反之则空头趋势。单单用这一段源码选股，条件不充分。

3. 股票预警公式 5 10 20均线最小口径或是粘合 报警的公式 谢谢！！！！

AA:=MA(C,5)>REF(MA(C,5),1);BB:=MA(C,10)>REF(MA(C,10),1);CC:=MA(C,5)>MA(C,10);{均线勾头向上}
 
CDJZ:=ABS(MA(C,20)-MA(C,120))/MA(C,120)<0.4;{长短均线距离绝对值越小越好}

8. C语言中如何用rand（）函数产生20-90的随机整数

rand和srand的用法
首先我们要对rand＆srand有个总体的看法:srand初始化随机种子,rand产生随机数，下面将详细说明。

rand（产生随机数）
表头文件: #include

定义函数 :int rand(void)

函数说明 :
因为rand的内部实现是用线性同余法做的，他不是真的随机数，只不过是因为其周期特别长，所以有一定的范围里可看成是随机的，rand()会返回一随机数值，范围在0至RAND_MAX 间。在调用此函数产生随机数前，必须先利用srand()设好随机数种子，如果未设随机数种子，rand()在调用时会自动设随机数种子为1。rand ()产生的是假随机数字，每次执行时是相同的。若要不同,以不同的值来初始化它.初始化的函数就是srand()。

返回值:
返回0至RAND_MAX之间的随机整数值，RAND_MAX的范围最少是在32767之间（int），即双字节（16位数）。若用unsigned int 双字节是65535，四字节是4294967295的整数范围。
0~RAND_MAX每个数字被选中的机率是相同的。

范例：
/* 产生介于1 到10 间的随机数值，此范例未设随机数种子，完整的随机数产生请参考
srand（）*/
#include
main()
{
int i,j;
for(i=0;i<10;i++)
{
j=1+(int)(10.0*rand()/(RAND_MAX+1.0));
printf("%d ",j);
}
}
   执行：

9 4 8 8 10 2 4 8 3 6
9 4 8 8 10 2 4 8 3 6 //再次执行仍然产生相同的随机数


srand（设置随机数种子）
表头文件：#include

定义函数：void srand (unsigned int seed);

函数说明：
srand()用来设置rand()产生随机数时的随机数种子。参数seed必须是个整数，通常可以利用geypid()或time(0)的返回值来当做seed。如果每次seed都设相同值，rand()所产生的随机数值每次就会一样。

范例
/* 产生介于1 到10 间的随机数值，此范例与执行结果可与rand（）参照*/
#include
#include
main()
{
int i,j;
srand((int)time(0));
for(i=0;i<10;i++)
{
j=1+(int)(10.0*rand()/(RAND_MAX+1.0));
printf(" %d ",j);
}
}
     执行：与rand范例比较
5 8 8 8 10 2 10 8 9 9
2 9 7 4 10 3 2 10 8 7
又或：
用"int x = rand() % 100;"来生成 0 到 100 之间的随机数这种方法是不或取的，比较好的做法是： j=(int)(n*rand()/(RAND_MAX+1.0))产生一个0到n之间的随机数
int main(void)
{
   int i;
   time_t t;
   srand((unsigned) time(&t));
   printf("Ten random numbers from 0 to 99\n\n");
   for(i=0; i<10; i++)
       printf("%d\n", rand() % 100);
   return 0;
}
除以上所说的之外，补充一点就是srand这个函数一定要放在循环外面或者是循环调用的外面，否则的话得到的是相同的数字。

MSDN中的例子。
// crt_rand.c
// This program seeds the random-number generator
// with the time, then displays 10 random integers.
//
#include 
#include 
#include 
int main( void )
{
   int i;
  
   // Seed the random-number generator with current time so that
   // the numbers will be different every time we run.
   //
   srand( (unsigned)time( NULL ) );
   // Display 10 numbers.
   for( i = 0;   i < 10;i++ )
      printf( "  %6d\n", rand() );
  printf("\n");
  // Usually, you will want to generate a number in a specific range,
  // such as 0 to 100, like this:
  {
     int RANGE_MIN = 0;
     int RANGE_MAX = 100;
     for (i = 0;    i < 10; i++ )
      {
         int rand100 = (((double) rand() /
                        (double) RAND_MAX) * RANGE_MAX + RANGE_MIN);
         printf( "  %6d\n", rand100);
      }
  }
总结：
我们知道rand()函数可以用来产生随机数，但是这不是真真意义上的随机数，是一个伪随机数，是根据一个数，我们可以称它为种了，为基准以某个递推公式推算出来的一系数，当这系列数很大的时候，就符合正态公布，从而相当于产生了随机数，但这不是真正的随机数，当计算机正常开机后，这个种子的值是定了的，除非你破坏了系统，为了改变这个种子的值，C提供了 srand()函数，它的原形是void srand( int a) 功能是
初始化随机产生器既rand()函数的初始值，即使把种子的值改成a; 从这你可以看到通过sand()函数，我们是可以产生可以预见的随机序列，
那我们如何才能产生不可预见的随机序列呢？我们可能常常需要这样的随机序列，是吧。利用srand((unsign)(time(NULL))是一种方法，因为每一次运行程序的时间是不同的，对了，你知道time() 函数的功能是返回从1970/01/01到现在的秒数的吧，可能这个起始时间不正确，你查一下对不对吧，C还提供了另一个更方便的函数， randomize()
原形是void randomize()，功能是用来始初rand() 的种子的初始值，而且该值是不确定的，它相当于srand((unsign)(time(NULL)) 不过应注意的是randomize()的功能要通过time来实现所以在调用它时头文件要包含time.h罢了
