【飞　狐】请高手看一下，我写的是否不太正确？

假若用以下四条均线选这样的股票。
M50:=MA(C,50);
M100:=MA(C,100);
M150:=MA(C,150);
M500:=MA(C,500);
M50L:=(L<=M50 and BARSCOUNT(c)<=50);
M100L:=(L<=M50 and L<=M100 and BARSCOUNT(c)<=100);
M150L:=(L<=M50 and L<=M100 and L<=M150 and BARSCOUNT(c)<=150);
M500L:=(L<=M50 and L<=M100 and L<=M150 and L<=M500 and BARSCOUNT(c)<=500);
最低价小于所有均线:M50L or M100L or M150L or M500L;股票论坛 www.55188.com
