Why do I see "Trends" in Randomly Generated Data?

    That is very interesting. I too have noticed a similar characteristic. I like to think of it as the decisions and events of the higher periods are randomly distributed in the period below. Though that theory would somewhat assume that the closer you go to the tick level, the more random the sequence becomes. Has anybody read anything about this?

    I would love to discuss more in PMs if you are interested, spike500.

    What cannot be? A trend? As I said, I believe a trend is an imbalance between buyers and sellers. I believe that imbalances derive from interpretation of news events and emotion (fear and greed at extremes). Ever wonder why the only thing that goes up in a down market is correlation? That is a pretty consistent trend...

  3. yes. Maybe back in the day prior to behemouth funds crowd behaviour and mass psych could be used as an argument for tech analysis and behaviorial finance. Now. The whims of one person SAC for example holds the same power as thousands if not millions of the crowd. I'm sorry but just for this reason. These pro trendtrading and tech a arguments hold very little water. It's time for a new paradigm if you want to thrive

  5. That observation makes the question raised in this thread meaningless,no ?

  7. I've done some tests similar to the OP, but more in depth, using randomly generated data. At first, I was also struck by the apparent existence of trends, S & R, and like things in the random data.

    I've since come to this exact same conclusion, and I think it sums it up perfectly: MORE RANDOM THAN MOST TRADERS THINK, yet MORE DETERMINISTIC THAN MOST ECONOMIST BELIEVE. Well said.

    This first part is the most important to me; markets being more random than most traders think (so trade accordingly).

  8. Yes, They finally guessed right.

  9. Yes... :) While finding the responses interesting in and of themselves, I have to admit a smile or two while reading through them because the basic premise of the question is flawed. The foundation on which the premise rests being that a computer can generate random data, which in fact, it cannot.

  10. SAC and other big hedgefunds guessed clearly wrong in the VOLKSWAGEN-PORSCHE bet.
    :D
