Hey lispers

if you language is so productive as you claim it to be, why aren't there any stock market tools that rule the market?

Actually there was a company that wrote some software in CL which is used to generate code for FPGA's for high-frequency trading. I can't remember the company's name, but I think it wouldn't be that hard to find using google if one tried.

Because Lispers are bright enough to realize they can't predict the stock market. quantsrdum

That Lispers can't predict the stock market says more about Lispers than anybody else.

It depends on what kind of prediction. Long-term predictions can't be reliable, but very short-term (second/minute-long) ones can be accurate with a over 50% success rate. The trick is getting the data fast enough and processing it fast enough (hence people buying servers as close as possible to stock exchanges and even resorting to using FPGA's to do the processing). This is how certain big trading companies are making their money, constantly selling/buying the same stocks, predicting very small changes/fluctuations.

Enron.

Enron went under for inflating its own stock. This has nothing to do with algorithmic trading.

That's a very short sighted way of leeching money from the system; it's a zero sum game. This sort of game goes against what the stock market was originally intended for: to attract capital to profitable and efficient companies.

Idealism and money don't mix very well, kiddo

>>12
Idealism is long term pragmatism. Time and time again, history shows that loose, shifty, and short sighted games (such as this example of stock manipulation) eventuates in catastrophes. Just take a look at the current Australian financial markets and Australian economy for an example of sensible prudential regulation and business affairs - the system as a whole has proven resilient to the various international financial problems.

I perceive the biggest weakness for Australia are China and Japan, Australia's largest trading partners. I predict that China's and Japan's problems will eventually catch up with them (I used to predict this would take 'a number of decades' but now I'm tending for two or three decades) causing damage in their capacity to trade with Australia which would cripple Australia's export market.

I think >>12 was just being sarcastic.

>>14
I know. I'm just too sensitive to the global financial problems eating away at my investments ;~;.

In that case you need a better algorithm

It's just how the system is. It's also considered an okay thing since it adds liquidity to the market. In the past, larger players used to cheat by buying early access to the stock exchange ( milliseconds/seconds... ), but that was deemed similar to insider trading, so they don't do it anymore. I don't think it it will lead to any sort of economic collapse, it's just a form of "skimming from the top" - like how you pay a small precentage to your bank/billing company/etc when making transfers. A similar kind of profit to that of being a market maker.

Don't change these.
