Glen has been actively investing since 2014 after attending a value investing course.
However as time passes, he realised that he had no system to screen, enter and exit for his trades. He did not get to learn how to fish for his meals but relied heavily on others for his investments.
He managed to earn an average 20% returns from 2014-2019, but eventually wiped it all out when he went in big (because his seniors told him too) on trading oil ETN which halted its creations and share prices plunged.
