Buying securities or currencies is somewhat like buying an automobile.
The decision to buy something is relatively easy.
What, specifically, to buy is an altogether different problem. Before you drive your new car home, you have to choose a certain make, a certain model, certain upholstery, a certain color scheme.
You decide between six cylinders and eight, between regular shift and automatic transmission, and say yes or no to white walls, radio, heater, and a dozen other optional extras.
