Now, what I actually intended to do and now must cut short being I'm exhausted from working all night. Anyway, lot's of good articles-A roundtable discussion on system trading caught my eye-"In my opinion, this concept gives credit to the argument that different markets have different personalities and, thus, behave differently. therefore while two different markets such as soybeans and the euro currency can both have long term trends, the narrower the time frame the more distinct their unique "personalties" are."-Peter Waite-SFO Magazine/Aug '07
As I mentioned before "tweaking" the basic system to the market may be necessary. ATR difference, etc.
