My background covers over 40 years, mostly as a stock/commodities broker (1972 -1983), then as managing general partner of a trading limited partnership (1984 thru 1989). This site is organized in much the same way a broker organizes his book: by client interests. Lots of choices are afforded depending upon your interests, psyche, financial condition, and experience.
Why not check out what is offered on this site; click on the area of interest for a .pdf explaining in more detail, the contents of that area.
All that for pennies a day. You could pay more and get a lot less!
