I've read every comment on this board (and its predecessors) for years, and I enjoy hearing the quant screens and methodology. Would anyone be generous enough with their time to describe - at a high level - how this works for them?

To be more specific - is it a full time pursuit? A retirement hobby? Rough figures in terms of trade frequency or how much of your total portfolio is invested at any time? How many trades outstanding at any time?

I'm trying to prepare myself for some interesting times ahead and change my trading habits to suit them. I don't know what degree of commitment I should be preparing myself for. I'm a fairly proficient mathematician and programmer, and relatively close to the cutting edge on software.

Apologies for the interruption.
