怎么实现在K线收盘前几秒触发OnBarClose

怎么实现在K线收盘前几秒触发OnBarClose我像下面这样写的，还不行，请指点一下 OnInit() { } OnReady() { Range[0:DataCount-1] { Array<String> TimeArr; //各个交易时段提前秒数 ArrayPushBack(TimeArr,\"22:59:55\"); //夜盘收盘(0.2300)K线收盘前10秒触发 ArrayPushBack(TimeArr,\"10:14:55\"); //早盘收盘(0.1015)K线收盘前10秒触发 ArrayPushBack(TimeArr,\"11:29:55\"); //午盘收盘(0.1130)K线收盘前10秒触发 ArrayPushBack(TimeArr,\"14:59:55\"); //日盘收盘(0.1500)K线收盘前10秒触发 Array<Numeric> timePoint; Integer i; Print(\"GetSessionCount:\" + Text(GetSessionCount)); For i = 0 To GetSessionCount() - 1 { Numeric ret = StringToTime(TimeArr[i]); Print(\"SetTriggerBarClose:\" + Text(ret)); ArrayPushBack(timePoint, ret); } SetTriggerBarClose(timePoint); } //Bar更新事件函数，参数indexs表示变化的数据源图层ID数组 OnBarClose(ArrayRef<Integer> indexs) { PlotBool(\"收盘触发\",True); If (BarStatus==2) Print(\"收盘触发时间：\"+Text(Time())); If (Close>Open) { Buy(0,Close); } If (Close<Open) { SellShort(0,Close); } }
