exp: i believe that chart/pattern/indicator analysis is the best use of my time;
I've been sharing some of my methods online since mid to late 1998, first on SI and since on IHub. I find it interesting how many folks are now using at least subsets of some of those methods I've been sharing.
To answer your question, I do use a "system" of sorts. If you are interested I expounded on a main component of my "system" such as it is, my Multiple Time Frame Analysis method coupled with chart patterns, trend lines, horizontal price action support/resistance levels and retrace levels. If you are interested, you might want to read through the IHub MDA Thread.
