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);
		}
	}
