Duma thanks for your response. Given your results on the 15 min system, I would be well advised to trade it, although I have a preference for the SPX. Are you holding ON positions with your SR15? Last I recall you were trading both the SR60 & SR15, so if they were in opposite positions at the close you were effectively flat. I will try sim trading the tick chart and recording the results, it would be easyest to tabulate the results in ES rather than converting it to SDS or SSO trades would thst be ok, or do you require the ETFs for % comparison?
