Goshawk Trades(@GoshawkTrades):a 1997 book on mechanical trading, on one of the main reasons I automate every trading strategy: "if you do not take trades from the system that turn out to be very profitable, you have changed the statistical basis of your expected returns and, in fact, could even lose money on a profitable system." skip three trades a month and you are running a different strategy with no backtest at all. the big winners in a trend system are a handful of trades a year. miss them by hand and the whole year can be ruined.
