I live by the method of getting your original investment back and playing with the "banks" money. You can sleep easy if you do this.
Same thing as yours, I live by that method, I admit that I it is a bit passive since this would likely result to any lose but I trhink this method is great and I also do that, as long as I get what I entered then I'll be fine and be active about this all through out since I am now more secured that I have not lose anything by doing this.
