Easy to use, and adopted by many successful traders over the years, William Dunnigan's One-Way Formula for Trading in Stocks and Commodities is a robust and reliable mechanical approach to buy/sell decision-making in speculative markets. A rare example of a 'universal' formula, this technique can be applied to almost any stock or commodity market, and requires little more than accurate line and bar charts.
To understand the union of these two books, we have to understand the author's ambition to develop a complete trading system which gave exact buy/sell signals for stocks or commodities, which was mechanical in all its applications, and which didn't require the user to make any mental decisions.
In New Blueprints for Gains in Stocks and Grains the author explores and introduces a full range of technical principles and lays the essential analytical groundwork for this universal formula.
