Range Rover Sport is V8, and Porsche Cayenne is V6. Range Rover is about 20K more
expensive than Porsche. Anybody
in this board bought Range Rover recently? Any price sample I could use to negotiate with the dealer?

但range stock 特别考验你的信心和耐心:
信心:买的时候一般会有很多负面新闻, 没有信心就很难作range

要有信心)就很重要

来自主题: Stock版 - Trending stocks vs. range stocks
To trade ranging stocks, the expectation is that the stock would not break
the current range. The more closer
it approaches to the ceiling, the higher risk it has. The basic assumption
is buying into support and selling
into resistance. Once a stock breaks out, it enters a new trading range,
which becomes another story.
I will post some backtest results later.

Alibaba's $80-$83 Opening Range in Context
by Maureen Farrell
We now know the opening range for Alibaba’s stock: $80 to $83 per share.
If Alibaba’s shares stayed in that range for the rest of the day, the pop
from its IPO price would be between 17% and 22%.
That’s below the average one-day pop for U.S. listed Tech or Internet IPOs
this year, which is 26%, according to Dealogic.
The average one-day pop for IPOs from all sectors this year is 13%.

It's really not how many times or how many balls you hit at the range, it's
the quality each practice session can produce.
I used to go to range everyday (or every 2 days), 70 balls each time.
However, I didn't have a purpose other than finishing these 70 balls and go
home and thinking you are practicing and improving. Yes, I did improve, but
at a very steadily slow pace - and often, improved in the wrong way, which I
had to correct in months (or years) to come.
In recent years, I go to range 1

Thanks everyone.
My biggest problem with irons on the course is losing distance, I can hit
straight on the course and range.
I agree that I do not hit down steep enough for iron, but that does not
explain why I have problem with woods on the range.
Maybe somehow, my plane is more steep on the range than on the course. I
will pay attention to that next time I step on the course.

来自主题: Golf版 - RANGE VS COURSE
对range上的球不要太看重就可以。 就不要想把RANGE上的成果转化在实战。这样实际
上给自己压力了。 everybody want to shoot lower score, but score is not
something to focus on. focus should be good decision, then commit to make a
good SWING.
range 只能用来在时间很少的情况上, 保持或work on swing mechanics on
standard lie. 作用有限。
我上次9洞看那个high school team player, 基本在场上练, hit a lot of second
balls, 看上去是在work on how to hit a better putt, better chip, better 2nd
shot.
场地不拥挤,一般9洞花时间并不多, anywhere from 1- 2 hour.

因为在HDR入门阶段,经常会作出很多效果很夸张的照片,摄影刚起步的时候往往会过
