True Range, Reward/Risk, And Position Size
In the May 2009 issue of S&C is an article by Alan Binder, “True Range, Reward/Risk, And Position Size.” I have a question about the calculation of the values in cells D16, D17, and D18 of the Input sheet. Most of the information is straightforward enough, but that calculation is a mystery. Could the author illuminate?
Alan Binder replies:
The numbers refer to the number of standard deviations for the indicated certainty values. Please refer to the Stocks & Commodities article, “Value At Risk And Technical Analysis” by Luis Ballesca-Loyo (August 1999, Volume 17: Number 8).
