LSS系统是一个很好的短线技术指标。

为了便于使用起见，我把LSS系统放在我所喜欢的主图指标里面。经过一段时间的使用，我发觉，它对于短线操作十分有用。就是在做中线时，在进行买入或沽出操作时，也不无参考价值。

现在，我把这段源码贴在下面，希望喜欢的朋友能费心顶一下，以便让更多的人能够看到。

下跌值:=ref(H,1)-MA(ref(H,2)-ref(L,1),3);
买进低值:=ref(L,1)-MA(ref(L,2)-ref(L,1),3);
今天低点:=ref(L,1);
趋势回档买进值:=((ref(H,1)+ref(L,1)+ref(C,1))/3)*2-ref(H,1);
买进值:=(下跌值+买进低值+今天低点+趋势回档买进值)/4;
上涨值:=ma((ref(h,1)-ref(l,2)),3)+ref(l,1);
买进高点:=ma(ref(h,1)-ref(h,2),3)+ref(h,1);
今天高点:=ref(H,1);
趋势回档卖出值:=((ref(h,1)+ref(l,1)+ref(c,1))/3)*2-ref(l,1);{LSS轴点突破买入值}
卖出值:=(上涨值+买进高点+今天高点+趋势回档卖出值)/4;
