He's old school, so he trades manually. He's agnostic as to whether his students trade manual or auto - that's up to each student.
In terms of process its along the same lines as what I described - he trades only fully tested models all tested by manual/spreadsheet statistics. In terms of putting a model into practice though his process (and the process he insists his students follow) is similar - demo mode for a minimum number of trades, then a nominal account ize, then scale up.
Personally if I reflect onthe scale-up process I describe it makes a lot of sense and also is aligned to what I used to do in product development / manufacturing. If developing a new product you start with a concept, then low cost prototype, then small scale pilot model, and then after costing and marketing anaylsis to develop a business case if it looks viable scale up to small scale production, iron out the bugs, then scale up further to full scale production with continuous improvement to keep improving cost efficiency, quality, etc.
