大概率（假設老川不發瘋），QQQ應該走個iv, 然後再衝v。但我說過很多次，subwave 不可靠。

490-510, in this range, anything can happen. Will need to see how market reacts. 

With elliot wave system, you want to get in the market in wave 1 and 2, and then just wait for market to run its course. It is ok if you miss the top (95% of time, you will miss the top), but if you bought QQQ at 400, 410, or even 430, it really does not matter if it stops at 490, or 500, or 510.
