That’s all in your head. A strategy or a system is never 100% accurate. They all work in some conditions and not in others. It’s about knowing when to make use of a certain trading system and not using it when you shouldn’t. If you keep looking for a holy grail, you will miss opportunities that you would have spotted otherwise.
When you are confident about your skills,you don’t look for the holy grail systems. It is good to improve your knowledge and work harder on the things where you are lagging. If you are not making any profits, there might be a problem in your trading plan or your strategy. Try to find those issues and make the required changes.Only you know what works for you, so you should try to create your own system.
Know that no trader has ever achieved success with one holy grail system. If you want to succeed in trading, you need all the elements from your trading tool box. One tool will help you in understanding the markets, another tool will help you in making buy or sell decisions and some other tool will give you an edge but there’s no one system that gives you all. If there was any holy grail, everyone would be using it and it’d be no secret.
