Another factor that will help you in judging the strategy is, to determine the win-loss ratio from it. It is just by understanding the difference between how much you earn and how much you lost. What this ratio means is just providing with average winning trades from the losing ones. Your buying and selling strategy have a greater ratio of losing than winning, that is a sign of not good strategy, and you should avoid it.

Look for another buying and selling system which holds excellent history of greater success ratio than failure.
