Trend traders don't expect to be right every time. In fact, on individual trades they admit when they are wrong, take their losses, and move on. However, they do expect to make money over the long run. In 1960, Donchian reduced this philosophy to what he called his “weekly trading rule.” The rule was brutally utilitarian: “When the prices moves above the high of two previous calendar weeks (the optimum number of weeks varies by commodity), cover your short positions and buy. When the price breaks below the low of the two previous calendar weeks, liquidate your long position and sell short.”
