通达信顶指标(绿顶红底指标怎么看？)
1. 绿顶红底指标怎么看？
绿顶红底指标，是通达信里面的一个副图指标公式，输入后可以看到该指标，该指标显示绿色时说明走势已经但顶部了，显示红色时表明走势已经到了底部，但是指标有延迟。
2. 求高手帮我编写通达信的KDJ顶背离和低背离选股公式？
J交叉:=CROSS(KDJ.J,KDJ.K) AND CROSS(KDJ.K,KDJ.D);{底背红买}K值:="KDJ.K";DD:=C=LLV(C,60);DDSJ:=BARSLAST(REF(DD,1));{上一低点时间}DDGJ:=REF(CLOSE,DDSJ+1)>CLOSE;KDZB:=REF(K值,DDSJ+1)
3. 请高手帮忙修改一下通达信的“XT箱体”公式？
【箱顶】:PEAK(3,N,1)*0.98;
【箱底】:TROUGH(3,N,1)*1.02;
下一行
【箱高】:100*(【箱顶】-【箱底】)/【箱底】;
可以不要，因为显示不好协调。
用作选股指标，可编成两个指标。
显示：
【箱顶】:PEAK(3,N,1)*0.98;
【箱底】:TROUGH(3,N,1)*1.02;
【箱高】:(【箱顶】-【箱底】);
选股：
【箱顶】:PEAK(3,N,1)*0.98;
【箱底】:TROUGH(3,N,1)*1.02;
【箱高】:100*(【箱顶】-【箱底】)/【箱底】);
4. 不小心碰了什么键，通达信顶栏没有了，什么系统，工具什么的，都看不到了，如何恢复？
通达信的菜单栏不见了，是因为通达信启用了屏幕管理中的全屏显示功能。快捷键是CTRL+P。要想恢复原最大化显示，再一次按组合键CTRL+P键即可。
5. 有没有百分百买入就涨的通达信选股指标公式？
这个指标有未来函数，就是假如今天出现了拉高的大阳线，买入信号就会在前天出现，这个是100%准确的指标，也就是非常不可靠的指标，等这个买入信号出现的时候，股价已经在顶位了！
