We don't want to complicated things though, there are a lot that is being mentioned by the OP. For me, just have a plan and then stick to us, simple as that. And some of the tips will go under this advise, like setting stop-loss order and others.
And with sticking to your plan, you won't be like chasing profits or losses. If you hit your target then good, and rinse and repeat and see how it goes. If your plan at some point fails, then you need to re-adjust and try again it is going to work or not.
