well you should look at your success rate history for at least a year and see if you were only getting lucky and making profit or were you actually making profit because your analysis was good and closest to reality and that made you make profit.
if it is t he former then you must stay away from trading and if it is the later then continue doing it.

but i'm guessing based on your topic title your trading strategy might have been more like a shot in the dark that sometimes hit the target in which case you might want to make some major changes in your approach.
