1) It is backtested so you will only know if it is good once you forward test it.
2) Even if these were forward tested results there are not really enough trades to be sure. One year of backtesting on a daily chart is not very much. That's the equivalent of me testing a system on a 5 min chart for one day> not nearly enough.
3) Why did you choose those? Was it because they had good trends in the time period, or because they worked better?
4) What was the maximum drawdown?
