Forward testing is performed either on a demo account or on a very small (micro) live account. During such tests, you trade normally with your strategy as if you were trading your live account. As with backtesting, forward testing can also be automated. In this case, you would need to create a trading robot or expert advisor to execute your system. Of course, with discretionary strategy, you are limited solely to manual testing. Forward testing results are considered to be more useful and representative than those of the backtests.
There is an additional rule for trading when the market state is more favourable to the system. This rule is designed to filter out breakouts that go against the long-term trend. In short, you look at the 25-day moving average (MA) and the 300-day moving average. The direction of the shorter moving average determines the direction that is permitted. This rule states that you can only go:
Backtesting is a kind of a strategy test performed on the past data. It can be either automated or manual. For automated backtesting, a special software should be coded. Automated testing is more precise but requires a fully mechanical trading system to test. Manual testing is slow and can be rather inaccurate, but requires no extra programming and can be done without any special preparation process. Any backtesting results should be taken with a grain of salt as the tested strategy might have been created to fit particular backetsting historical data.
Trend-following systems require a particular mindset, because of the long duration—during which time profits can disappear as the market swings—these trades can be more psychologically demanding. When markets are volatile, trends will tend to be more disguised and price swings will be greater. Therefore, a trend-following system is the best trading strategy for Forex markets that are quiet and trending.
