Thanks in advance.  Your work is very helpful and much appreciated.

You're confusing Greece and Portugal.  As to your question:  Western Civilization.

Tom, it's an honor to have the same thoughts as you.  Unfortunately, it's doesn't look so good the other way around.  But maybe we can both figure out how to infuse some option leverage into the SPY system while controlling risk.  And Tumbler, thanks for all your great ideas.  

Very interesting and a concept I agree with.  Cherry picking systems, thereby turning them into discretionary trading, is almost always counter-productive.

Now, a question.  Since the second buy signal in the multi-entry scheme has a higher success rate than the only entry in the single entry system, I wonder how it would work using options.  There are fewer trades, but would having a higher success rate coupled with leveraging compensate for that?

China is a communist country with a centrally controlled economy.  I thought such economies weren't supposed to work and that they would lead their countries down the path to poverty.  So how come China is winning the war of the global marketplace?

I agree with you about not posting messages that people agree with you.  This is somewhat akin to "All Romans are liers," said the Roman.

A kind member reminded me that "gone against" means, in this case, that the price of SPY ihas gone lower than the entry price.  I thank him/her for the help.

I was asking about precisely that, Tom.  The price has certainly gone against the first entry.  Is there a point when the sytsem would scale in (for the multiple entry system, that is)?

For educational purposes, I would be curious as to why the system won't be phasing in today after such a sharp decline in the market.  Please understand that I'm not questioning the system's signal, I just want to understand it better.

Yes.

I think that the problem is that we're using two ideas interchangeably.  You're right, Susan, Matt did discuss a profit target that is rarely reached.  But the original question was about a sell stop (i.e., the price the system would have to reach to issue a sell signal).  Clearly, these occur much more frequently than the profit target (i.e., one per buy signal).

I don't know this to be the case, but I can't imagine a dynamic system such as this one has fixed profit targets.  I assume that the sell signal is recalculated daily.  

To what systems are you referring?

Thank you for the data.  Now, I wonder what UPRO would have returned.

Congratulations, Matt.  

In other words, are the results roughly the same since SSO started trading (letting us extrapolate back to before it was availabe?)

Would the statistics be essentially the same going long and short SSO, or do Profunds perform better?

What the video says about silver may or may not be true (I'm a silver bull, fwiw), but the video itself has the feel of a tacky late night infomercial.

I want to caution people in another sense.  It is very easy to muddy the waters between trading a system and trading in a discretionary fashion.  In my experience, that doesn't work.  If you start choosing which trades to take in a mechanical system, you're doing discretionary trading, period.  A mechanical system can only work if you trade it mechanically, and not try to outsmart it.  And, to speak for myself, I'm a lot dumber than a good mechancal system.

Having said that, mechanical systems can stop working.  That's why it's important to monitor a system, keeping a sharp eye out for its profit curve.  If it starts to curve down significantly, it's prudent to turn the system off until the profit curve looks healthy again.
