You only need to call Randomize() once, and so if your programneeds randomnumbers, just include the call in the form load event. Several mathematical methods have been developed for accomplishing the task of generating standard normal deviates, including the well-known rejection method with the Box-Muller transformation, which can be converted into program code. However, we prefer a much simpler method, as shown here: Function StdNormRnd() As Double Return Rnd() + Rnd() + Rnd() + Rnd() + Rnd() + Rnd() + Rnd() + Rnd() + _ Rnd() + Rnd() + Rnd() + Rnd() - 6 End Function In all cases, this method will suffice, and the StdNormRand() function above will be used in this book.
They also provide fuel to carry a market higher or lower.
