kovu, check out a daily chart of QQQQ with Heiken Ashi bars. Go long when green; short when red. Less whippy than the 2 MA method described in that article. Just a cursory look at it looks very good. Yes, some whips here and there, but you catch all the big trends as well.
If your charts don't offer these, get quotetracker (free daily charts with free data feed) and use those. Check it out. This might actually work.
