  2. The point is that there were 18 and 23 in 250 to 300 boxes. It is not that there were 23 in a row that is interesting.

  3. isnt there a thread in the oil futures section where someone called someone 'grasshopper' then promptly got their fucking head handed to them on a wrong long from 57 down to 35?

    The market is not random.

    All coin toss examples are pretty much useless in the context that you will never find 2 identical market participants (a head and a tail) such that the weight of the coin is exactly distributed. One participant will inevitably have a larger weight (skewness) to the market outcome due to the non linear functions which all participants are comprised of.

    Hence, there are trends in "random" data.

    Ivan, do you trade real money?

  6. Not sure. I trade USD. In my neighborhood they consider them real.

    My trading method has nothing to do with this discussion.

  7. Let me ask this another way. How many throws do you need to determine if a coin is fair?

    Right. But, since you trade real money, I just wonder if you can teach us a method that works 100% of the time, since you believe markets are not random? Thanks.

    The coin will never be "fair" in the sense your thinking of. You're implying a Gaussian distribution which is not what markets operate under.

  10. Someone flys a plane into a building, but before they do, their friends buy put options on the airline stocks.

    The airline stocks go down, and their friends make profit, so is that random?
