In all honesty, the answer is nothing. Everything important, in terms of the major principles of trading and the path to success, is freely available here and in other similar places. Not only that, but these principles are endlessly repeated. The most useful books are well known and are also available on the internet for anyone to try before purchasing them.
Most people simply do not want to believe that these principles apply to them. They prefer to hope that the answer can be purchased, or will be given to them by some improbable philanthropist.
I would say the following to a new trader:
1. The secret to success is to fully appreciate that there are no secrets.
2. Trading is the same as almost every other endeavour - success is mostly a matter of hard work, learning, and perseverance.
3. It is all but impossible to trade somebody else's method effectively. You must reach your own conclusions or profitable execution of a method of trading is all but impossible over the long term.
4. Everyone's path will be different, but logic and reason are key to success. Be sceptical, and ensure that you understand why you are using anything that you use. If it is not logical and rational, it is almost certainly harmful to you.
5. It is entirely possible, using only what is freely available on the internet, and spending at the absolute most a few hundred pounds on books, to design one's own method of trading that will allow one an excellent chance of achieving long-term success.
