elliotwave, When I read your initial post, I (mis)read "patterns" as "chart patterns", for example: Head and Shoulders. My latest intraday automated strategy under development notes the trend direction and scalps for a fixed profit target. According to my imperfect backtesting it only became profitable on the ES after 06/11. More than likely I'll keep working with this strategy, test it in market replay and sim, and study how/which market conditions affect its performance. I may also see how it works with higher time frames.
I am certain that the market is perfectly organized to appear like perfectly random. The rest is easy.
just for fun,i can't program and watch these together,spx,djt,then aapl,xom,x,and bonds,eur/usd, can barely use computer so if this is a lot of work,don't bother but watching for s/r in spx using the eur,djt for confirmation ,noting s/r in all at the same time,seeing if it turns early on 1 or 2 and the rest follow,or if it breaks on 1 or 2 and the rest break,,works maybe 70% of the time
I'll reply when I make some progress. In the mean time you might be interested in the book Evidence-Based Technical Analysis: Applying the Scientific Method and Statistical Inference to Trading Signals which is often suggested as a good primer to the type of data-mining statistical analysis you seem to be referring to.
