Always “protect” your money by using stops. Mental stops
are okay, but not if you are dead serious about using a “disciplined”
approach to managing your money. You will lose three out of ten
trades. The three losses should be kept to minimum. Your wins will
by far surpass your small losses, and that’s what stop-losses are all
about. Don’t be afraid to lose. Even professional batters strike out six
out of 10 times. Lions are only successful 20% of the time in their
chase for the kill. Professional golfers lose 95% of the time.
Professional poker players lose 50% of the time. So, your chances
are better at trading the forex, than in
any other venue. Even businesses have “bad inventory.” And, life in
general is not always “100%” for sure.
