I am on everyone's mailing list and I received an interesting solicitation
for a gambling system.&nbsp; I love to read the promises.&nbsp; This one
had something interesting in it that many of us have tried to express to
the new traders.&nbsp; It struck me that this particular paragraph applied
to trading as much as to horse racing and other bets of chance.
<p>"Each wagering game, including horse racing, has a set of probabilities
which govern the possible outcome of any given series of results.&nbsp;
Most believe those games with a "minus" probability ( a House edge against
the player), cannot be beaten over an extended period of time because the
percentages are against them.&nbsp; This is not always correct, because
there are two sets of probabilities, one minus and one <b><font size=+1>positive!</font></b>&nbsp;
Everyone else only uses the minus probabilities to prove their point about
so called gambling games.&nbsp; When in fact, almost all Casino games and
Horse racing, have a positive probability also.&nbsp; When this <b><font size=+1>Positive
Probability</font></b> is greater than the minus probability in a particular
game, the game can be beaten...in fact... the game must be beaten in the
long run!!!! A game with a positive probability would be any wager game
in which three factors must be present...&nbsp; The player is not required
to play constantly, ( the house must always play)... the player can change
the amount of the wagers whenever they wish, ( the house must always bet
what ever the player wagers).. The player can quit playing whenever they
want ( the house must be ready to play whenever players want to)"
<p>For Casino substitute Exchange. For House Substitute Locals. For players
substitute traders. Games of chance substitute futures, stock or options.&nbsp;
Not a bad analogy.
<p>The claim is that after 12 years of study by a renowned Swiss scientist.
...... who has proven, without a doubt...there is no gambling...&nbsp;
I only posted this for reference. I found it interesting.&nbsp; Ira.</html>

There was a book written some years back called "RACETRACK BETTING" the
authors were Adams and Quant, both professors(at Princeton I believe).&nbsp;
It was a discussion of paramutual betting and the concept of how to bet
and conditional probability.&nbsp; It quickly became "required" reading
for many of the best traders at CBOE.&nbsp; I would strongly encourage
anyone really serious about trading to get a copy and really understand
it(I haven't checked amazon.com to see if it still in print).&nbsp; This
is a strong statement , but of the handful of people I know who trade for
a living and claim to have understood it ......All have accumulated net
worth's in a range that most people would envy.
<P>I would strongly encourage anyone really interested in understanding
conditional probability and option trading to read it.

I just checked with AMAZON and the book is out of print.  If you can find one I would still go for it.
