Mining for profits in modern markets

摘要

The approach to most market timing in the early 1980s went something like this: Calculate a particular indicator over N days, buy the market when the indicator went to X and sell when it got to Y and, possibly, sell and go short when it got to Z. There usually would be a chart associated to demonstrate the virtues of the strategy based on the last half a dozen or so signals. This was around the same time when desktop computers were becoming common, if not at home, at least on the majority of traders' office desks.
