RSI有时管用有是不对。这个大家都知道，RSI还没有死说明它在特定条件下有用。
本人对QQQ20年数据进行了分析。方法：先把RSI分为3个区，1： less than 30, 2: 30 to 70, 3: larger than 70.
1）： 然后mark the zone changing point. (转区时间点）， 计算跨区以后，1，3， 5， 10 天的表现。 比如，从1区跨到2区的日子是 12/5/2016 （谁便举例）， 那么从这一天算起，随后1，3，5， 10 会如何呢？你可以认为是要起飞了。也可以认为不见得。 Another example : someday the RSI changed its zone from 3 to 2, do you think the down trend will follow in next few days?
2）： 每次转区以后都有个表现，比如+、- percentage and average +/-. And same time, I will calculate the +/- distribution in time series. Thus you may find what you might take action when zone changing happens, and what was happened in last few times for this kind of zone changing.
If you want to know a specific stock result, then simply tell the ticker name, I can calculate for you as well.
if you interested in the calculation result, PM to me. Same time, get ready to share your most comfortable secret as trade. I may not respond you if you do not share your secret or experience. Good luck！
