Hi There FXP
sure I have used correlation as part of my trading strategies for 20 years now ....
however they will be at best average in raw forms if used alone ......
all of my linked free systems and indicators available here and in other places (that I am not allowed to mention in breach of prospecting rules as applied by moderators at T2win) offer a lot of information on how to incorporate Strengthmeters into trading systems and i have worked with hundereds of traders and programmers over the years to develop their own bespoke sucessful systems
so in answer to your question...........
I have been successful in my trading for many years now, by incorporating Strengthmeter based strategies and indicators
however i also incorporate other indicators, price action strategies and other techniques to augment the core Strengthmeter platform......its a portfolio of elements
Cheers
N
