Not sure why you would want to know about a "bad" course but I can recommend Al Brooks as having produced a good one. There are a legion of folks on the You Tubes of the world looking for clicks, subscribers and credibility.....dime a dozen. You don't however need any course good or bad if you are willing to do the considerable work to understand price behavior.
Price does the same thing whether it's Paul Tudor Jones or John and Mary "spend my day jerking around on Elite Trader threads" watching.
Spend a number of months,depending on your ability to focus and understand what you're seeing. What happens when price spikes...does it tend to continue..does it tend to revert back to it's base?
If it starts to trend, what is the slope of the rise or fall, what is the nature of the consolidation flags? How long do they last? Do they tend toward continuation or reversal?
If it looks like price is "overbought"/"oversold"..is it? Is it more likely to continue to or reverse? Is the upper trend line sloping at a different angle than the lower one?...What might that mean?
Put a MA such as a 20EMA (nothing magical about this number), does it help define the geography of price development for you? What is the slope...does that make a difference? Add pivots such as prior day's high, low and close and current day open...what happens at those levels if anything?
Bottom line, a smart and diligent technician can help you understand what you are looking at but don't expect anyone to tell you how YOU should trade. NO two people trade just alike because no two people ARE just alike.
Do the work, observe, test, learn and if ...IF you work hard enough, you might have a chance.
