Invest your money, not your ego. Even the most carefully-crafted system is going to lead you astray eventually. Conditions change. Markets change. And even a system which is working just fine may have to be altered because of a new data point. Always be willing to adapt. Unwillingness to change your mind can cost you more than you’d believe. Never let a trade become an “investment” merely because you failed to listen to the market.
