Algorithmic optimisation --- the new frontier for Expert Advisor programming. :cautious:

I have found minorize–maximize (MM) algorithms are derived from expactation-maximise (EM) algorithms.

I think this may be the basic algorithm (EM) that programmers use to determine lot sizes BUT i`m not sure.

there is a really simple EA which can take $10k and turn it into $1.5 billion.


...on a backtest.

after full optimisation.

and increasing lot sizes.

u put it on a live account. itll kill it in 2 days :p: . everytime. i think the longest its lasted was just under 2 weeks.

Just to add, I read on FF:



Was wondering if the same happened to you or still going by demo results?

(serious question!)

I have activated my EA with Go Markets. I have traded it on live account before they declared it not to be used.

No I did not take the losses you refer to.

Oh and so far the EA has accumulated more pips than it has lost.

Believe it?

Go Markets as you are fully aware have closed it down so it cannot take trades.

Now I don't know what part of my posts are ...... "sniffing bull****"..... bull**** so if you think I am full of it then say so and give me a reason to believe you.

Just come out and ask serious questions without all the bull**** in the first place.

Like I've posted before I am not here to ramp the product. Just here to share my experiences. If you don't want to know about my experiences then don't waste your time reading the "bull****"

You obviously believe mechanical style Trading Systems which are fully automated are doomed to lose money in the long term.

maybe have a look at this Masters Thesis on the use of EM algorithms with Hidden Markov Models of Forex: http://liu.diva-portal.org/smash/record.jsf?pid=diva2:17431

From my experience these kind of algorithms, which can distinguish between local minima/maxima and global minima/maxima, are more important when deciding to take profits, rather than regarding lot sizes.

i dont think it helps that your username is taken from a commercial EA product. it immediately sends up red flags to many.

can you run that FAP backtest with money management off so that lotsize is consistent?

Yes I second that.Apart from the mathematical formula sections I found the thesis very interesting.Tells me that the big end of town have a better grasp on auto-trading than the (end of food chain) retail sector does.

I'm doing some extensive backtesting mate to really give this thing a work out.

At this stage I'm finding out that this EA is not as good as reported. However over the long term it does make money but there are periods of drawdown which could be a problem.

I'm being up front here and not trying to bull****.

Please see the backtested report here. This is achieved using 90% Modelling

http://www.sendspace.com/file/k18ufi

Using a high leverage setting during those periods of drawdown would really hurt an account.

Anyone considering using this EA needs to be fully aware of that.

:D So what you are showing us is ... every dog has its day.Seems like knowing when to switch the thing on and off is worth examining.
:2twocents
 
I don't know what sort of optimizations are done on this EA.

Seems to be some curve fitting has been done for recent periods which has given this EA some sort of profitability.

Too much curve fitting can be a problem.

Like I've said before the only real test is to do forward testing.

Having backtested gives some idea on how it has worked. Does not mean it will continue to work. The market is ever changing.

I don't know how you determine if a system is broken. What sort of drawdown would you take before you decided to stop.
