I'm doing several studies on random trading in the markets and wish to make
sure I'm getting a true proxy for randomness. Currently using perl's built in
rand function like this:
$number = int(rand(100));
Gives a random number between 1 and 100.
Using this function over a large number of simulations, a random trader's
average trade converges to the vig/trade or to 0 with no vig - as one would
expect, so it seems I'm getting good randomness. However I realize the
limitations of the rand function and am wondering if anyone here has a better
method. Or is this type of rand function sufficient for an analysis of random
trading?
