generally the mech systems only work for the symbol they are set
up for. If you backtest different symbols -- say SDS instead
of SSO, or QID instead of SKF - whatever -- you get very different
results. You would have to be doing your own backteating to
find other moving average combos that work with different symbols
-- which many poeple on the blog in fact do...............
you can buy URE instead of shorting SKF, but you have to do it
on a signal using SKF -- you can't use URE for the
signal................................
Or do the homework/backtesting/optimization required to have
confidence. I am tradeing URE long with one system and SKF long
with the 9/39. Sometimes might have a conflict and end up
effectively "flat" like with Ravun's 5& 15min systems but
that's OK.
yes, of course you can backtest different systems............I
had SRS and URE both running for a while, both on 6 min charts, but
with different parameters, but it drove me nuts. Way too
often I'd have psoitions in both of them losing
money...............dropped it and haven't gone back to it
yet...............

Matt, Is there any reason not to use sds or qid for trades on the mech. systems?? Please some feedback....

if you can't short SRS

if you can't short SRS then obviously go long the opposite ultra ETF
You can either short the

You can either short the long ultra etfs or buy the inverse versions, same effect, I believe.
