    Reversion to the Mean

    Not sure if I understood the question but no matter how large the number of tosses you expect to find the number of Heads around the mean +- some standard deviations. Standard deviation grows with sqrt(n) so after 1000000 tosses typically the number of heads will be around 500 thousand +- a...

    Paradox?

    If you have hundreds of thousands of independent random bets with a small proven mathematical edge to profit from during a year time-period then the cumulative result is very far from random. The only real danger for a casino is an unforeseen non-gambling related event -maybe a fire :-).

    Enough sample data?

    Under ideal conditions (meaning the back-testing time period is an ideal representative of what you can expect from your system in the future) an estimation of the validity of above metrics can be made using the formula…. Actual number is between: backtesting result – 1.96 *...

    Position Simulators

    Of course you can. You only need to change the cells references in the VBA editor a little. Here is a quick example of the same spreadsheet a little altered to handle 20 leg positions. I hope I didn¢t mess the code.

    Althucher guesses: trend funds to disappear within the next 10 years...

    Hi. First of all I would like to say that I am not a trend follower. However I find it hard to believe one could argue that trend following is not working at all.

    Mark Johnson¢s PGO free trend following system was less complicated and was working better than the Turtle Rules in some of the markets I back tested but don¢t take my word for it :). Regards
