You can only do this if you know what you are doing, and of course, if you know how to manage your risks and your losses in a proper way (without getting desperated if you lose a trade)
Instead of managing the risks and losses, I think we should think about the profits when making. It will motivate us to be more certain, and of course, should not make investment blind, must think carefully!
Sometimes we should also consider how to manage the risks that you may take whenever you would go trading "prevention is better than committing mistakes". But of course we should focus on a positive way, focus on the profit that we may gain if we can do it perfectly and properly and be a wise thinker.
