Quote from Hook N. Sinker:

This random walk stuff is nonsense.

OK lets see what happens if I begin trading General Electric stock 2 January 1962 and stop trading 18 July 2006. This mechanical system has these three rules:

1) Buy when price first increases above the highest price of the prior 400 sessions.

2) Sell when price first decreases below the lowest price of the prior 400 sessions.

3) Size positions so that the number of dollars to risk stop is 10 percent of account equity.

Number of trades 5
Total profit $ 2944958

Cumulative Annual Growth Rate (CAGR) is 66.28 per cent.
