Obviously you're going to get a billion different answers here. It's working now, there is no reason to think it will stop working. When (if) it stops working then you have some work to do. If it continues to work you still have some work to do to increase your equity curve (unless you are perfectly satisfied with 44-70k a year, which would be fine.) Ultimately your question as to the significance of your results can only be answered by your analysis of your system/situation. Which is why I didn't want to post a response to this initially. If this is your first time being net profitable then you're probably going to have (and what I assume prompted your post) high emotions "what if it stops working, what if what if what if..." Don't let yourself think that way....simply say "what I have done has made me money, if I continue to follow my rules, I will continue to make money. If I suddenly find myself in a losing streak/drawdown outside of normal parameters (which you must define) and I have not disobeyed my system, ...then I will look for the problem. In short, you are the answer you seek.
