However, only this version using some strategies and signals.

Hi,

a systematic large-scale analysis of Super-Trend parameter influence and recommendations for the best parameters for all major FOREX pairs is given here:

http://tradingresearch.wordpress.com/2011/08/15/evaluation-of-super-trend-indicator's-parameters-for-all-major-forex-pairs-over-12-years/

(tiny url: http://wp.me/p1M1iZ-6)

The analysis is based on >12 years back testing for each currency pair.

Hope this helps in selecting your best parameters :-)

With Best Regards
