快几十倍(c++ vs php)。新系统我准备每天扫描所有股票3到10遍，从所有股票中找到
100只以内值得做
的做5分钟的跟踪。其他都是按天分析。
系统做好以后是可以实时通知的(email, sms等)，甚至可以直接交易（做成功了准备上
ib）。如果版上有
哪些牛牛们对这个东西有兴趣可以和我联系，给我提供点意见和算法。做好以后可以为
大家服务，提供
email list。
我的gmail是p*******[email protected]，或者msn:p******[email protected]
PS:旧的系统大家可以看下 phoenix.linkpc.net，现在这个系统里面没什么数据，因为
要重写才放上来
对照的。系统界面做的比较简陋，因为大部分都是后台运行，前台只是一个调控。大家
可以去stock
portfolios 下real panel看下，这里面都是可以追踪的原始数据。

华为硬件很好，软件系统太封闭，举个例子
1.mate20居然不支持双击亮屏，从去年上市
用户就在花粉俱乐部反映，始终没有，最恶心的是后来的p30居然有双击亮屏，同代产
品不同待遇，mate系列比p系列还高一点点
2，google语音用之前要手动打开，关机再开机，系统会偷偷把语音助手自动改成none
3.经常来电来短信不提示，这一点最可怕，别的功能再牛逼，不提示电话和短信，这个
手机就不是个合格的手机
4.小艺助手是个没啥用的骚货，我叫它设个40秒倒计时它都不会，更别指望开车时候让它
帮我找最近的加油站了
两句话总结，好用的时候真好用，不好用的时候想砸了。

1. fundamental数据有，但是只有profit,book value一些基本的，没有预测。
2. finance yahoo不会告诉你哪知股票要涨，哪知要跌
3. 现在同时跟踪2000只股票只要大概1个月数据库就很慢了，新系统做好后我只打算留
6个月的5min数据，剩下的都放到daily data里面。
4. 云计算什么的都是个形势，主要是算法和数据，以后升级很容易的。现在我的服务
器是双xeon 3.2gh 4gb ram, 10000rpm。对于目前开发测试我觉得差不多了。
5. 现在我的broker不支持auto trade，所以这个只能算个push alert,不过改auto
trade很容易。
6. 我看看couchDB，现在考虑为每个stock每月建个表
7. 由于是改写，进度很快，估计到下周新系统就可以接收数据了，之后就要写
indicator和signal了。我个人对ta还不是很了解，还指望nns不吝赐教。

谢谢大家关心
1. 我知道这个东西一个人做很困难，所以才来版上请教各位大牛。我觉得现在就已经
有很多人给了我很好的新思路。如果有志同道合的也可以一起探讨合作。
2. computer can beat human brain in the market是我的信仰，
3. 像本版大夫这样的牛人更加强了我对有一些人可以beat the market的信心。
4. 这个系统倒不是一定是要短期交易。我认为交易时间段是由利润和交易成本决定的
（commission，spread等，有margin还有interests）。
5. 现在可以说是一个real time screen,但自己的程序可以写自己的screen criteria.
上一个程序流产的时候我正在写一个identify trend & pattern, resistance &
support的程序，虽然也是screen,但我想很少有软件有这个功能吧
6. 而且这个软件还包含portfolio管理，就是说它不光告诉你买卖什么，还会告诉你多
少，根据不同的strategy控制风险和利润
7. 这个软件的最终产物将会是trading signal,即买卖和数量。对于软件来说会screen
,会analyze,但对于user来说只有买卖和数量，其他神马都是浮云，要不也就不叫auto
trade了。
8. 我要求5min信息主要是因为我认为每笔交易对于股市都是由影响的，得到的信息越
多预测的越准。比如说一个股票一天一直升到最高点和到盘尾一下窜到最高点从daily
chart看是一样的，但对于以后的预示可能完全不一样。
9. 如果我能证明我的模型能挣钱，你认为我会发愁没钱运作么。
10. yahoo里面也有fundimental信息，我那个表上的信息都是从yahoo搜集的，从其它
网站的信息不在那个地方。
11. 我过两天试试看纯文本。我专业是会计，对计算机都是初中开始自己慢慢学的，很
多地方还不是很懂。不过我现在的系统一些简单的常用数据都是用文本(track的股票，
信息什么的)。如果信息比较复杂如何很快查询呢(比如有bid, ask, volume, trade，
我想查所有trade between $x and $y)。还望牛刀兄多多指教

看你这么热情，就说两句。
这板上90%以上是挖苦和讽刺，还有就是来寻求虚荣心的。从你总结的那么多点看。
你要走的路还好远好远，我从一无所知到build你这样的system大概两三个礼拜的样子。刚开始也
很热情，如果只是把make money作为动力，恐怕热情不会持续这么久，如果当作一种消遣，可能对
身心更有益。
2. beat the market做信仰可不行，beat market概念上，只要买write covered SPY
call就by definition beat the market了。。。。
4. 频率是由你想找什么样的inefficiency决定的，高频对于licensed member的机构比
较实
际，他们不需要交commission，还可以拿到大量liquidity rebate，如果你想花M（不
记得具体
多少了）买一个交易所的membership也可以。如果叫commission的话，越高频越难做，没
commission的情况下，SR达到上千上万都有可能，有commission，。。。。如果想入门
，可以参
考一下Irene写的那本Introduction to HFT
5. 看你的描述似乎是想做swing style的，这样做个beat market的strategy挺多，也
不难
做，比较beginner的做法大部分是static的思路，最多每天开盘前必要情况下重新
evaluate一下
结果，adjust parameters一下。我在刚学习的第二个月做过static的backtest。
6. PM的model很多，而且一直在发展，我前面推荐的paper里面有reference很多流行的
model。那些用online PAC learning+boost可以显著地beat传统的PM model。
7. 比你想的要复杂，execution值得优化的方面很多很多，可以参考一下这本书，
Kissell, Robert (2003), Optimal Trading Strategies.
SAC capital的人作序的，比较经典。
8. 做swing，5min对你帮助有限，做day trading，5min只能分析走势，做signal不够。
9. 如果我能证明我的模型能挣钱，你认为我会发愁没钱运作么。
你会，因为卖模型的人太多了。看看C2上面的strategy，或者你看看wealth-lab上的，
反正现成
的strategy没有十万种也有一万种了。你是无法prove的，即便你能拿得出非常好的
track
record，非常漂亮的各种risk/reward指标（这个也一直在发展），如果自己没有一定
规模的资金
实际地操作半年一年，没有人会买你的帐。例外我也遇到过，不细说了。
11. 很多人都说了，strategy远重要于技术细节，技术细节属于慢慢tuning的工作，有
时间了可
以RAID存储，快很多，SSD也快可以RAID了。或者可以尝试一下GPU computing。挺多大
公司已
经用这个做simulation相关的计算了。

1. 你推荐的东西我一定会去看的
2. 我从php改c++还有一个原因就是要gpu加速。我一个朋友就是做这个的，他答应我以

3. 做这个算是个课余爱好吧。白天上班，晚上和周末就做这个。除了想赚钱以外，也
希望通过做这个程序在trade这方面有点研究，以后可以进个ib,hf，或者申请个phd什

My experience of data mining shows that indeed sophisticated systems
sometimes tend to overfitting the data. And for black box models you don't
know what is going on in there. Just like blindly following GPS may lead you
to a wrong place. So I think simpler but more intuitive ones tend to be
more robust and might be helpful in decision making - not necessarily auto
trading, but as a facilitating tool.

The market is "simple" in the sense that it's always about demand and
supply and history repeats itself again and again in a very broad base.
Beyond that, we can only say market is extremely complicated. The
information presented and digested by the market is way way beyond
human technology to ever process.
Actually, human being can never master financial market because the
purpose of observers is always to interfere. And the resulted interference
by its nature is to invalid the original observation. It's like a cat
chasing its own tail. In that sense, astronomy has a much brighter

there's lot of evidence that the market in US is at least weak efficient
which means by looking at historical price, no one can gain anything from it. I believe with the wide availability and current speed of tools for mining and analyzing data from public filing. The US market has already been or will be semi-efficient soon, which means on one can gain after looking at public data filed by companies such as fundamental data derived from sec filing.

I agree with you that "human being can never master financial market because
the purpose of observers is always to interfere" and we can never
completely predict the system behavior. However, the system has its own
momentum and inertia, besides, the mass majority of the participants are
followers, not leaders or active participants like frogs on this board. So I
believe it is possible to predict the direct of a trend in a SHORT FUTURE
HORIZON.If the majority of the money is controlled by MM equipped with
sophisticated trading strategies, then it would be much more difficult for
individuals to make money in this market.

I agree with you that market has its momentum and inertia. That actually has

But note that chasing momentum is itself re-enforcing the momentum, or in
other words it's a positive feedback. We know positive feedback only makes
the system increasingly unstable. So when you loss, you loss big. It
eventually becomes a game about getting in and out ahead of the crowd,
while participators are actually the crowd. Like all games, there are always
winners and losers. But can there be a constant winner? I doubt.
The only way to beat the market to bet against the crowd. However, this is

Okay, here is what I suggest (and also what I am practicing):
1. The first of first is to keep in mind that winning in a trade in
financial market is a matter of probablity but never a sure thing.
Now everybody will say "I don't need you to tell me this, I know
from the beginning." Well, I know you know, but you didn't really
keep it mind, because when it comes to the next question, not many
people really use their brain.
The next question is: if somebody made some money in one trade or a
few trades, is it because they had a right strategy? or because they
are nothing but lucky.
When people think carefully, they all know how important the answer is
to the above question. But the reality is: People are so used to their
daily physical world, where good method produces good result and bad
method produces bad result in sort of certainty or at least a very high
probability. This gives them an instiction to make judgement that
good results must come from good method and bad results come from bad
method, without even think twice. Unfortunately, in financial markets,
good results can very much likely come from bad method, not forever,
but within some period. Of course, bad method will eventually yield
bad result in total, but the effect can take some time to show up.
It took sometime for people to get rid of this instinction when making
judgement in the market, yet for some people they never really understand.
If you agree with what I said above, you can keep reading the rest part.
Otherwise, forget all negative things I have said, no bad feeling and
keep on your happy trading.
So what the hell this bullshit has anything to do with trading? Well,
it is very related because it will yield a series of negative conclusions
about what you probably have trusted.
The first one I am going to challenge is Technical Analysis, which I am
sure everyone know and 95% of people on this board are putting their
full faith on. My conclusion will be -- TA is an illusion which only
works when you look back but never really works when you look forward.
To be continue...

TA中有一些东西是具有高概率的预测作用的，当一些条件苛刻时，出现的几率下降，而
成功的概率上升，，，完全否定是肯定不对的。当然现在太多人并不真正懂得技术分析
的作用和有效性。
一个技术指标或形态，如果被许多人知道，那有效性就会大大减弱。但是有些东西是和
大众心理直接相关的。因此，即使很多人知道，但大多数人的心理还是和100年前的散

来晚了，先支持下。
我也在做一个自动交易系统，第一步的目标和你类似，也就是一个screener。
数据从Yahoo Finance上抓，目前抓的是S&P 1500大概1500个股票的EOD数据。
split和dividend数据。刚作完adjusted close。下一步打算作stragegy和backtesting。
目前的系统用的Ruby写的，目前用CSV存EOD，下一步打算用C#重写一下（Ruby确实比较
慢）和Tokyo Cabinet （一种Key-Value store)存10min or 5min。
和前面几位的建议一样，如果是要作自动交易系统的话，strategy是最重要的，you
must have an edge. 另外从我做的research来看，tick data cleansing和order
management要比想象中的要难。

All right, part 2, Technical Analysis.
I threw out a little hint at the end of part 1 by saying TA doesn't
work, and it got some defensive words back already. It will be
interesting to see what happens after I finish this part, because
if you accept what I am going to say, you probably will have to start
over in your trading adventure (which I think you should).
It is worth a few words to talk about what TA is trying to solve
first. Market price, no matter what the underlying product is, all
comes down to supply and demand. FA usually tries to evaluate the
underlying product and believes that supply and demand will eventually
converge to the true value. But evaluation itself is a very difficult
job if can be done at all, not even ask if the market price ever
converges to the true value. (I'll talk more about FA in next part.)
TA, in a broad sense, is trying to get around this evaluation part,
leave the job for other smart guys, and look at supply and demand
directly to guess the next move. I have to say it WAS a brilliant
idea, at least a good try, in the good old days (maybe 120 years ago).
In old days, people don't even have a chart in front of them. Drawing
the basic price chart at that time was a very professional job that
only a handful people or trading house can do. Being able to read a
chart was a huge advantage not many people can enjoy, that's why I
guess maybe it could work at that time. (Even though, the famous Dow
Jones Theory, the grand father of all TAs, born in 1890s, had been
already proved worse than simple buy-and-hold by 1920s.)
TA methods today can be roughly divided into two categories. I call
them 'chart TA' and 'book TA'. Chart TA is a set of methods based on
historical prices and volumes. Book TA is a set of method based on
exchange books (e.g. Nasdaq Level II quotes.) Chart TA can be further
divided into two sub-categories. I call them vertical analysis and
horizontal analysis.
Vertical analysis is the one attracting the enthusiasm from most of
you, i.e. look at the historical price and volume of a stock or index,
try to dig some information from it, be it patterns (e.g. head-shoulder,
flags, candlesticks, etc.), lines (e.g. trend lines, moving averages,
resistance/support, Elliott levels, Fibonacci, etc.), and their derivatives
(e.g. A/D lines, Arms index, MACD, etc.) I cannot list them all because
there are hundreds of them. If you read Technical Analysis of Stocks &
Commodities Magazine, you'll see new TA indicators are being invented by
somebody somewhere every single day, and they all look great!
Vertical analysis has been applied by traders in all time frames,
from years to ticks. John Magee in his legendary book Technical Analysis
of Stock Trends (first published in 1940s, still being read by readers
overall the world today) suggested that round top and SHS are only
meaningful when formed over 1 or 2 years, and round bottom can take
even much longer. And he gave very attention to the volume pattern
accompanying these price patterns, claiming that without the correct
volume setup the price pattern cannot be trusted. Yet after so many
years of 'evolution', I see people commonly refer to these patterns
in minute charts without even look at the volume. (I am not trying to
say John Magee is right, just to present a spot that many popular
TA methods actually come from nowhere, not even the original idea
of the inventor.)
Horizontal analysis is a group of methods trying to profit from the
correlation between stocks or markets. It includes a lot of different
methods. (You may be thinking long short hedge fund, but no, they
are actually more on the FA side.) I have seen people doing things
from as simple as plotting the charts of two stocks together and
visually identify the correlation to as complicated as using some
statistic theory that I never heard of and a few 16-cpu servers to
trade a basket of stocks and commodities. There might be dozens of
ways being tried but they all come down to one idea: correlation
in prices without fundamental.
Book TA is probably more advanced to most of people on this board
although some of you might have tried to learn reading Level II or
ECN book. The idea is to look at the book or market depth at the moment
to identify the location of liquidity, either to execute large chunk of
order or to predict the movement for the very next moment. This type of
TA by its nature can only be applied to high frequency trading. However,
it's pretty much all they care in many sell-side trading house and market
makers (where the word MM comes from and very much associated with market
manipulation, although they are absolutely not most of you have thought),
and thus an area of real professionals. This is an extremely competent
battle field which has absolutely no space for civilian traders. I knew
trading houses full of PhDs paying millions of dollars a year just to get
milli-seconds ahead of others to access certain market. You get the idea.
Book TA is a pure mathematic science. Which stock you are trading or even
what you are trading is actually not relevent. The touch of this area
is both out of retail traders' capability and out of their interest. So
I am not going to talk about it any more. There are always somebody
believe that they are smart enough to try it. I'll say that's like a
civilian with or even without a gun trying to fight an army.
I'll go back to talk about chart TA again.

Thanks for the post, very informative. It deserves to be a seperate blog

If I understand you corretly, the book TA you mentioned is actually
quantative trading, where you can apply some more sophisticated strategies
over a relative bigger number of stocks or other instruments. Though myself
is a very newbie in this arena, I personally don't think those a bit more
advanced topics such as pair trading, risk management, Sharpe ratio,
backtesting are beyond the capability of retail traders like us. You do need
to know what a game you're going to play tho.
Just my 2c, look foward to your part3.

Book TA is not what you have mentioned, not at all. I don't know why
you get that impression... please read again. If you are interested
what it's really about, you have to look at the market depth, Nasdaq
Level II quote, or ECN books. If you don't really know what these
things are, it's okay to forget them altogether. As I said, it's not
a field for retail traders.
Pair trading 应该在 horizontal chart TA 的范畴里。Just remember,
whenever you forget fundamental and look into historical price for
answers, you are in chart TA.
Risk management is another story, not related to what I am trying to
solve here. Backtesting is not only in the capability of retail traders
but also something they should have done before they use any TA indicators.
If they ever do that seriously, they will understand none of TA works.
I'll talk about it in more detail later.
