reality check v2.0
on 4th November 2007, i posted a similiar post. back then, i took a step back and reviewed where my search was going and made a few points that still holds for me today. you can re-read that post here : http://ckowyong.com/blog/?p=63
this is going to be a long post. many people may not agree to what i’m going to say, but those who are familiar with the forex market and expert advisors should be able to appreciate it. so please read with an open mind if you have about 10 mins to spare, ok?
clickbank and other forex affiliate products
i was recently asked about Forex Beater that costs US$49.95. if you visit the link for it’s affiliates, it states that it gives a commission of 75% off the sale price. that means the seller gets only about US$12.50…and that’s not even considering how much ClickBank gets out of that miserly US$12.50. if something really works, it must be worth much more than that!
a fellow forex blogger also wrote about the Expert Advisor business here :

the above link is a good read, but it may dampen your spirits a little if you are still in a stage where you get all excited whenever you read one of those long and well crafted websites that sells Expert Advisors.
the SWITCH
the following link brings you to an interview with Mr Thomas Bopp :
http://championship.mql4.com/2008/news/371
it’s not obvious, but near the end of that interview, Thomas mentioned something about a SWITCH. a few months back, i attended a forex talk by Kathy Lien. she too mentioned about this SWITCH.
market conditions changes from time to time. most often in unexpected ways and times. there are trading strategies that works great in a certain market condition, but fails when it changes. banks and institutions have spent years trying to develop a SWITCH that could monitor the market and switch to the most profitable strategy as and when market conditions change. according to Kathy and Thomas, this automated SWITCH does not exist…. yet.
on the other hand, the best SWITCH that we’ve got is likely the trader in front of your computer right now. an educated and competent chart reader who understands the fundamentals is our best bet.
in other words, invest in your education. there’s no short cut in this game.
mean reversion + martingale = DISASTER
if you do not know what these 2 terms mean, below are their explanation from investopedia.com :
http://www.investopedia.com/terms/m/meanreversion.asp
http://www.investopedia.com/terms/m/martingalesystem.asp
time and time again, we see EAs coming into the market that are based on the above 2 theories. they work great in a volatile ranging market, but once it catches a strong trend on the wrong side, it would crash faster than you can say “what the…”.
how to tell if an EA is based on the mean reversion or the martingale theories? the only way is to scrutinise it’s trades. if the EA seller’s website does not offer a statement for you to check out, you will be pretty much clueless about how it trades.
don’t get me wrong. such systems (or any hybrids of them) can be very profitable. that can produce amazing profits and generate beautiful back and forward test results. but what’s lacking is the SWITCH that we mentioned earlier. with good money management and a seasoned human SWITCH, once could still make some money with such a system.
but in general, systems that uses these theories and touts about it being a fully automated system should raise lots of red flags. in fact, a fully automated Expert Advisor that does not require human intervention or regular optimisation is equally suspicious.
back testing and optimisation
here’s another great interview with William Boatright, Yuriy Zaytcev and Olexandr Topchylo :
http://championship.mql4.com/2008/news/376
with the lack of a highly intelligent Expert Advisors that can adapt to all sorts of market conditions, one of the best approach is to run backtests and optimise. the caveat, however, is that past performance does not equal to future results. realistically speaking, what can guarantee future results anyway!
but if an Expert Advisor or strategy reacts well to optimisation, then optimising the system periodically would be the way to go. many of us are still trapped in the “If it’s a good EA, it should not require any human intervention or optimisation.” mindset. well… aren’t we all looking for the Holy Grail that does not exist?
conclusion
this is going to dampen a lot of hopes out there. but from what i have read and from my personal experiences (and many others in the FaceBook group), all i can say is that Expert Advisors are great trader’s tools. they are excellent and amazingly efficient in executing the programmed strategies, but in my honest opinion, Expert Advisors are best used as tools only.
to trade successfully with Expert Advisors, we first and foremost need to know how to read the charts. and with good knowledge of how the EA works (as well as it’s strengths and weaknesses), we can then deploy the EA to do it’s job at the most appropriate situation. we have to be fully accountable for our own actions, and that includes the evaluation, purchase and employment of any strategy or system.
so… the search for the best trader’s tool continues. for me, i’m sticking to PIPForia and Bogie for now. using them requires some effort and education, so they are not your typical plug-and-play “Holy Grail” type of Expert Advisors.
please leave a comment if you find this post useful (or not).
good trading to all!
