I've been discussing my efforts for building a trade system with a couple people more than others and it dawned on me that both people say that it took about five years before their program worked so that they were very happy. It was about 3 years before it was useable. I'm wondering if that is similar to most people's experience? The question here would be (for people who are trading real live systems and consistently making money from them only please): How long did it take before you had coded an automatic trading system (bot) which earned consistent income? (Not when it was perfected.) thank you!
