做波段很不错的指标通达信指标公式源码通达信（TDX）是国内知名的股票分析软件，采用C语言开发。
在TDX中，可以通过编写指标公式实现自定义技术指标。
下面是一个使用通达信指标公式源码实现的简单的波段指标示例。
```javascript#include "stdio.h"//定义波段指标计算函数void BollingerBands(int n, double *close, double *upper_band, double *middle_band, double *lower_band)int i, j;double sum, sum_squares, sd, temp;//计算SMA（简单移动平均线）for(i=n-1; i<total_bars; i++)sum = 0;for(j=i-n+1; j<=i; j++)sum += close[j];}middle_band[i] = sum/n;}//计算标准差for(i=n-1; i<total_bars; i++)sum = 0;sum_squares = 0;for(j=i-n+1; j<=i; j++)temp = close[j] - middle_band[i];sum += temp;sum_squares += temp * temp;}sd = sqrt(sum_squares / n);upper_band[i] = middle_band[i] + 2 * sd;lower_band[i] = middle_band[i] - 2 * sd;}int maiint n = 20; // 计算波段指标使用的周期长度double close[] = {1.2, 1.5, 1.4, 1.6, 1.8, 1.7, 1.9, 1.8, 1.7, 1.6}; // 收盘价数据//计算波段指标double upper_band[10], middle_band[10], lower_band[10];BollingerBands(n, close, upper_band, middle_band, lower_band);//打印波段指标结果printf("Upper Band:\n");for(int i=0; i<10; i++)printf("%.2f ", upper_band[i]);}printf("\n");printf("Middle Band:\n");for(int i=0; i<10; i++)printf("%.2f ", middle_band[i]);}printf("\n");printf("Lower Band:\n");for(int i=0; i<10; i++)printf("%.2f ", lower_band[i]);}printf("\n");return 0;```以上代码实现了一个简单的波段指标计算函数BollingerBands，并在主函数中进行了调用和打印结果。
天赐良机一副图波段参考王参考副图屮，红色波段意为持股，浅蓝色波段意为持币，深蓝色波段中线趋势走势，提供支撑阻力参考位，另亮点是副图指标10区域下方的黄色片区，意为买入信号，90区域上方的红色片区，意为卖出信号，可根据黄色、红色片区面积大小做参考。
