My advice is to try and keep it simple.
If you remember this then you'll not go far wrong.
Learn to spot a Market that is trending and then jump aboard. Ok, an oversimplification perhaps, but do the basic well and you'll save a lot of headaches.
No indicator is fool proof, and no matter how good a trader you are you will make a lot of losing trades. Learn to accept this and this will help.
Do the simple things well would be my advice
