1分钟图表策略指标不显示

1分钟图表策略指标K线数多时几万K容易不显示,5550K线时显示正常的，但走着走着不定时会不显示,开平仓也不开平了,策略用行几个月别的分钟图表没发现这情况,信号也没有闪烁现象，策略用的是开盘价和前1最高最低价,老师帮看看是什么原因。下面是我策略用到的数据和公式， n3n = RoundDown (n3*0.1, 0); n2n = RoundUp (n2*0.1, 0); n2r = RoundUp (n2*0.7, 0); n1r = RoundUp (n1*0.7, 0); hi = h[1]; li = l[1]; ma3 = Average( open, n3 ); Q3 = AvgDeviation(open,n3)*1.5; q3r = Average(q3,n3n); H3 = MA3+Q3; L3 = MA3-Q3; ma2 = Average( open, n2); a1 = XAverage( open, n2) - XAverage( open, n3 ) ; a2 = xAverage( a1,n2r); Q2 = AvgDeviation(open,n2)*1.5; Q2r = Average(q2,n2n);//轨道线 H2 = MA2+Q2; L2 = MA2-Q2; n1h = Highest(Hi, n1); n1l = Lowest(Li, n1); ma1 = Average( open, n1); b1 = XAverage(open, n1) - XAverage(open, n2 ) ; b2 = xAverage( b1,n1r); b3 = ma1+(b1-b2)*2; ba1 = NthCon(CrossOver(b1,b2),1); bv1 = NthCon(CrossUnder(b1,b2),1); 35000K不显 5550K显示正常的
