I started working on a big project, not sure what it's going to
look like in the end but started testing. We have the SPY reversion
to mean systems as you know. So I'm taking those same systems and
running them on 15 - 20 of the sector ETF's so in the end have a
basket of reversion to mean systems on the market and sectors. I'm
not sure how much overlap there will be, obviously there will be
but maybe it won't be bad and everything will be pretty synergistic
as a group.
This is a big project. I basically have to run back tests on say
15 ETF's with 22 sub systems each, that's a lot of testing. YES I
run back tests for reversion to mean. I know that back testing is a
bad word in the systems community, and used in the wrong way it is.
That said, in my opinion reversion to the mean systems are all
about finding rare and important statistical events of the past
data, you can't get around that. So to me it's necessary, you have
to run tests on the past 20 and 30 years to see how the indiviidual
statistical variations of those ETF's, you can't just use one
setting for everything it depends on the instrument (well you kind
of can but then you deal with low profit factors and what's the
point. Anyway with say 15 - 20 ETF's we are looking at 400
backtests, and generally I will run refined tests on those many
times - so this could be a 2 or 3 month project if everything is
looking good and I decide to do the full tests. On Friday's like
this and at night and weekend's I'll be running tests.
That said, let's say in the end I'm able to get this to work.
Logistically I will probably have to chance some of the alert
system to be able to handle it. For the SPY systems right now I
send alerts for sub systems spread across multiple charts. For
these ETF's I won't be doing that, I'll have all sub systems on one
chart, otherwise it's too much to follow.
Also currently I send out option alerts for the SPY, well for
the ETF's, especially if multiple trigger in one day will be
difficult for me to do that. So I'll probably send the alert with
what my parameters are for the options - for 1st entries I target
expiration dates 2 months out with a 0.6 - 0.7 delta, so you
can just use that info to pick the options, or just do the
Lastly - the email system can be delayed - I think the best way
to handle alerts in real time would be a BPT systems alert APP that
you would install from the AAPL app store or the Google Play
store - then you simply get alerted through your phone on the
anyway that's some things I'm working on, if this all works out
it would be probably a couple months - and it's possible that after
I get into this I find that the stats are not worth it, so it's
very preliminary, just letting you know what I'm working on the
Use search function. Options, Matt
regarding the reversion to mean systems I said last week that I
was looking to add these systems to a collective group of ETF's
instead of just SPY.
As I stated this is a big project to do, adding all these sub
systems to each of these ETF's will take a long time to test. Over
the weekend I've tested the Bear Long sub system to most of these,
but you can see how many more systems I have left, again it's going
to take a month or two in order to complete this; for example it's
taking since Friday through the weekend just to do the Bear Long
tests with my computer running all day and night, big project. Then
of course I have to see how much overlap there is, for example on a
pullback in an uptrend I really don't want 10 or 15 of the ETF's to
trigger long at once, ideally a few would at most, but we'll have
to see how the data looks as I get more of it.
Anyway this is the list of ETF's I'm looking out. I also threw
in EEM and IWM index ETF's. I may consider GLD and FXE and maybe
TLT as well as those are pretty uncorrelated
I would like to see GLD in your R2M system.
Thanks for the innovation and hard work, Matt. Those
should be very useful. I know there are scope creep
concerns, and this usually has high correlation with the S&P
500 (I believe), but DM ex-U.S. (e.g., VEA or SPDW) /or its two
main constituents, Europe (e.g., FEZ) and Japan (e.g., EWJ) would
be interesting, at least to me. That, along with EEM, would
cover most of the world. I remember that rundown you did of
all the country / regional ETFs and it was interesting.
Here's an updated table, this is the ETF's I'm testing, at the
bottom you can see 'other' which are non correlated to the general
been working on these, mostly done with one sub system LOL.
So much more to go
anyway the bottom ETF's are pretty non correlated to the index
and sector ETF's.
looks like there would have been a FXE Euro reversion to mean
trade last week.
trying to get the bear long finished on GLD, tough to get good
numbers on that ETF
Thanks, I like some of those like FEZ makes sense, SPDW and VEA
interesting. Though I"m trying to stick with ETF's with data back
as far as possible
This will be awesome Matt, thanks!
This would be incredibly valuable (assuming the backtesting
validates it), and a significant enhancement to the BPT
subscription. I would think you would want some compensation
for all of this work. Maybe you can charge a one-time price for the
app to help offset your time investment. The app would of course
still require a valid BPT subscription to operate.
That will be fascinating, especially if the winning % is
close to the current SPY system.
Sounds like much work but could have huge benefits for the
Thanks Matt !
Awesome concept, your always improving BPT. Best value out there
by far. Have you considered a fund that trades on systems and
members buy shares? Not sure the legality and headache on your end
for that though ??
I would put all my account money in that fund.
i like the phone alerts i have missed last five trades as i am
working on a project at home or rentals or my church etc and some
folks here still are working so that would bee great to get alerts
on our phones. sounds like great plan! another thing i like about
BP always trying to grow and move forward setting still is never
