void OnDeinit(const int reason) { //--- destroy timer EventKillTimer(); Comment(""); }
在停止时，用空字串清空屏幕，确实有用。
int OnInit() { //--- create timer EventSetMillisecondTimer(60); //--- return(INIT_SUCCEEDED); }
我觉得用 Tick + Timer 更有效率，Timer 间隔较长，Tick 变化快时，同样可以触发。
当市场不活跃时，由 Timer 触发。
int OnInit() { //--- create timer EventSetTimer(UpdateTick); //Comment(""); // clear all. myTick=UpdateTick; orderChkPos=0; //--- return(INIT_SUCCEEDED); }
void OnTick() { //--- myTick++; // when makrt on hot, tick is go up fast. if (myTick>UpdateTick) { myTick=0; checkOrders(); } } //+------------------------------------------------------------------+ //| Timer function | //+------------------------------------------------------------------+ void OnTimer() { //--- myTick=0; checkOrders(); }
