Graham worked as a technician in telecoms and two-way radio for many years. In the late 90s/early 2000s studied and gained a B Comp Sc and then worked in software development for 5 years. Employment then became patchy and Trading became seen as a means to an income. This was done (shares on the ASX) secondarily to looking for work and completing an MA(App Ling). In the 2010s trading became the focus. Knowledge has been gained from the ATAA, books and online research. He now uses Amibroker to model, test and identify stocks mainly in the mean reversion world.
