You can hit a mental saturation point in trading, this is the point where you’ve absorbed all the trading theory and knowledge that you need to trade effectively, and by taking in more knowledge / information / training beyond this point you are actually hurting your chances of trading success. Bob was convincing himself out of good trades and into bad trades, again this was from trying to absorb too much data like economic reports and other news variables, as well as the differing trading methods he was trying to use simultaneously. Similarly, in trading, you can learn to trade from an experienced trader like myself, but after you’ve obtained the knowledge and mastered the trading concepts, it’s time to ‘take off the training wheels’ and start trading yourself.
