求教！！！一个从不同周期取指标值的 新问题
原因可能是在M1中，同一个bar中首先出现了金叉后进行了标记，然后不久价格降低，金叉不成立，而你的指标没有重画的功能，之前的标记没有消失。
我想应该没有你说的情况，你想我能在M1标出，应该就能在M5标出才对啊，不管它是不是真的金叉或假金叉，M5只是取M1的数据，不是取M5自身的数据
也许原因出现在我的M1数据是不全的，即不是很连续的，有时会丢失1MN，或2MN的
不知你的数据是否完整，能帮我试试吗，看是数据的问题，还是程序问题，你可以试试这个新程序，直接把均线画在M5上，另外，原来iBarShift(NULL,1,time,true)的 true 现改为false，这样就跳过不连续数据，你可以试 true 的情形又是怎样，谢谢！！！

始终用timeframe周期k线计算，就不会有交叉点丢失的现象。屏幕显示的k线，不用做为计算依据，仅做为画线的背景图。
用M1[2]、M2[2]替换了M1[]、M2[]，减少了内存使用量。
