Greetings Mr. Covel,
The greatest challenge (se far) has been getting started. I have some knowledge of statistics, but I have no, and I mean NO knowledge of trading. I dabbled a bit in stocks and cryptocurrency, but it was sheer luck that kept me afloat so far. I simply want enough knowledge to be able to plan out a strategy, put it to the test and fine tune it over a decade or so, making some profit with my limited funds along the way. What I lack is a structured guide as to what to look for, where to look for it, and how to react. Not a detailed plan per se, just some guidelines to at least know what to look at and understand next.
I hope that answers your question.
