有两种办法实现根据tick数据触发信号。第二种值得推荐，代码简洁。

1. 时间邮戳

   
   

   extern bool EnterOpenBar = true; 
   int CurrentTime;
   int init(){
   CurrentTime= Time[0];
   return(0);
   }
   int start(){
   if (EnterOpenBar) = true)
   {
   if(CurrentTime != Time[0]){
   // first tick of new bar found
   // buy and sell conditions here
   CurrentTime= Time[0];
   return(0);
   }
   }

   
   

2. 成交量检查

   
   

   extern bool EnterOpenBar = true; 
   int start ()
   bool OpenBar=true;
   if(EnterOpenBar) if(iVolume(NULL,0,0)>1) OpenBar=false;
   if (OpenBar) {
   // first tick of new bar found
   // buy and sell conditions here
   return (0);
