I have a friend, a great trader, who also publishes
research papers, which in his own opinion, do not have any real value
for trading. In general, people will never publish something for real.
The same is true for trading programs. If a program works, no one will
sell it to you for a million dollars!
There are many trading programs on the market for a few thousand
dollars a piece. Those programs are usually incorrectly optimized.
They are not statistically verified and will only help you to
lose money. Garbage in, garbage out, there are indeed too many of them.
I myself have never spent a penny on them.
Nevertheless, reading papers and books is important, as it may provide some
useful ideas. If you read 10 papers and 5 books and obtain one useful
idea, it is good enough.
A fund manager said that he had bought many many trading systems with source
code and only found one that worked and that was good enough. But most retail
traders don't want to invest so much with so small a chance.
What I want to say is that before spending some real money on this,
you really should think twice. It is much better you just get some vague
ideas and develop your own systems. Small managers are very reluctant
even to out source the coding job lest their ideas be stolen.
Large funds hire many people so that each individual knows very little
about the whole system. |
