I also never heard of a training course that will be universally praised - some question the merits of training courses per se, others question the merits of specific courses, while those same courses also have their strong advocates. There is no doubt that not all courses are worth the money, but in terms of sifting through the remainder, you will get a pretty confidently-expressed range of opinion.
I took a training course and swear by it, others on here will think that I wasted my money, trouble is that we are all different in terms of how we learn, the support we want, whether we prefer group learning or solo study or a mix of both, how highly we rate coaching, there are many factors. Not trying to sound negative, I am simply saying that even a course with good, documented results will have its detractors, so it ultimately boils down to personal preference.
This being a mostly-anonymous, internet forum, you have no way to check the bona fides of anyone posting an opinion. So by all means use us as a sounding board, just remember that it is your money to invest, so don’t feel afraid to go against the majority. Some would say that that is one of the key qualilties of a successful trader, in any case - the majority view across the population as a whole would be that we should all stop this and find 9-5 jobs, after all!
This discussion generally boils down to two broad schools of thought: a) much of the information taught on the courses is available cheaply/for free elsewhere through a range of internet sources and books. So therefore it is a waste of money giving someone thousands of pounds/dollars whatever to teach you something you can get vastly more cheaply elsewhere, your cash would be better invested in actual trading. Alternatively b) that is all well and good, but it is worth paying a premium to gain that knowledge with some context, some quality control, from an experienced trader who can walk you through step-by-step in person how they trade, why it works, what does not work so well, which elements of knowledge to prioritize, with some trading strategies thrown in, as well as ongoing coaching. There is a lot of great stuff on the internet, but also a lot of rubbish. Also, some aspects of trading knowledge are more important than others. Having someone walk you through all that is helpful to some.
Fact is, there is no definitive right answer, it is down to personal preference.
Another factor is how much seed capital you have. If you are looking to start trading with a small account, say $100 or $200, then a decent training course is beyond your means. If you have $10,000 to invest, then you still have a decent starter pot once you have paid for a course, so you are at least able to consider it.
Anyway, sorry to ramble on, when I started out looking for a course I found it all pretty confusing, so I thought that you might find this helpful.
