i live in a third world country and work on low minimum wage job , im interested in us stocks trading
when i googled how to choose stocks i read about many ways something like technical analysis( considered by some people a form of snake oil), fundamental analysis for the country (gdp,inflation,etc) for the stocks(financial ratios like earning per share ,income statement).
i use something like cfds( CFD stands for 'contract for difference), a type of derivative product that you its cheaper in my country compared to buying a real stock .
what are your advice to me what type of analysis i need and how?
