People are skirting around the unpleasant, the direct, and ultimately the truthful.
This is a business. A ruthlessly competitive business. The information in the public domain is structured to keep the public active in the market. This from pension funds and stocks n shares ISAs down to spread betting and retail forex accounts.
The truth of the matter is that you will not find the information you seek on the Internet. I would suggest that you get exposure to successful traders if you can. Try and find a mentor, or failing that proper training in an institution. In the old days, one could be a clerk / runner on the floor and learn from the locals. More difficult now with screen trading.
Alternatively, develop your own hypothesis in isolation with your own thoughts and logic. You need to be a very special person to do this and it will take you years.
Rather than what has been suggested to you, perhaps obtain a copy of Victor Niederhoffer's "Education of a Speculator". Notably he explains how the costs of the industry (exchanges, infrastructure, commissions, spread, slippage, analysts, etc) must all be paid out of the losses of the public. Similar to betting on the horses or the casino - the house takes its cut out of the total amount wagered. This will give you an idea of where you currently are in the food chain, and how you can evolve to being predator rather than prey.
If you aren't serious about this as a business and have some spare cash to lose, then you can choose to jack it away in the markets without taking years to learn what you are doing.
Regarding charging for mentoring - don't be suckered. Nobody is going to sell you the holy grail for £5k. Most of what is taught by this ilk can be learned elsewhere. A proper mentor will qualify you using something else other than ability to pay. They choose you, not the other way around. Suggest that you get a job in the industry instead. A professional background will help you to understand what exactly you are in, and provide you with a living until you develop the skills required to go it alone.
Yes, I see that this website has sections with basic information for newbies. Having looked at some of it, I would venture the following question:
What work, if any, has been done to evaluate the validity of the information?
I am not making a call on whether it is valid or invalid. It appears to me that the vast majority of participants here are hobbyists and employees. Where are all the self made multi-millionaire traders who started in the T2W "First Steps" section a few short years ago? Do we have any proof of the validity of this information? Given that trading is frequently described as being "more art than science" - how can we test the utility of any of this?
Is it valid simply because it is mainstream and orthodox? Is the market constructed to benefit those who read the T2W first steps and get started right away with their first spread betting account? Is this the approach that the consistently successful actors in the market deploy? Is it an institutional or professional approach? As far as amateur traders, there are many who have built significant personal fortunes. Using this information or similar information?
