Brokers don’t hunt individuals they hunt the “textbook trader”. Brokers promote their learning academy’s and other sites because they promote rules like “place your stop loss 10% below the open of the order” etc
The best traders I know learnt trading through applying unconventional wisdom.For example,a mentor of mine in LA used to be a boxer. He understood “zero sum games” and how successful boxers got “in and out of the danger zone thousands of times during a fight”.So he applied that to day trading.
Once he hit his number for the day he was done, because another rule he learn’t in boxing was “retire boxing and don’t let boxing retire you”(we all know boxers who fought on way past their prime)
I’m not saying don’t learn from their academy’s but I am saying be critical and learn from different sources until you develop your unique style so your not “the textbook trader”
