wenlong, you have shown a previous interest and seemed sincere. i am sure you are just startled by that large negative number and that your comment meant no ill will toward the thread.
actually, this drawdown is not ridiculous at all and might even have been anticipated from our prior research. for your benefit and others who might also be concerned, let me explain a bit. here is an equity chart for the eur/usd for 19 months. that covers our original test period and adds july.
you can see at least four months where this pair lost pips. other pairs have also had three or four losing months. now, there exists a mathematical probability that while e/u was losing, some other pairs might have been losing at the same time, epecially if we broke the data down into weeks instead of months. depending on how many pairs start losing at the same time, we may see an overall drawdown in the portfolio. that is what we are seeing now as the markets are producing very little movement in any pair and several are losing simultaneously.
is this to be expected or is this the first losing month for a method that will never perform again? who can say for sure? that’s why there is a constant disclaimer that “past performance is no indication of future results.” all we can do is keep our eye on the performance and give it up if we are sure it has quit working.
i cannot think of any method where it would be impossible to collect either historical and/or contemporary results. for crying out loud, just look at a chart and see what would have happened if you had done such and such. but, a contributor offering a system for consideration by other traders has many choices on whether to report that information and how to report it. these are some variables, some legitimate, some malicious, that factor into that reporting or lack thereof:
- the contributor may not know how to go about collecting performance data;
- the contributor may be too lazy to do the work required;
- the contributor may have an ego in the way and find it necessary to save face in losing periods by simply misrepresenting the results;
- the contributor may not offer results data because he/she knows the system is “iffy,” doesn’t know for sure whether it performed or not, probably doesn’t want to know for sure, and doesn’t want you to know;
- the contributor may be offering something that is just an idea, still in the development process, and is legitimately seeking input to determine whether the approach has any validity.
these, and many other determinants keep us from having valuable information that might help us decide whether we want to pursue a method or not. without implying sinister motives to any contributor, there are any number of trading approaches on this site and others that use attractive marketing verbiage, “amazing, highly accurate, profitable, no losses, 40 pips a day, sure thing,” etc. many of them offer no results information of any kind, some offer results that cannot be replicated and verified, and a few are so obscure when it comes to the actual trading rules that stephen hawking couldn’t figure out what to do.
so, which way would you prefer to have your results? how about this. how about we do our best to build at least something of a historical picture of how the method probably performed in the past. then, we start collecting and publishing contemporary results so you can see how the system is doing since it was introduced. how about we get our egos out of the way and do our best to report these results without bias or preference. the results are transparent and the collection methodology is explained. that means you can do your own research and see what you get. this way, you get to see the data, warts and all. you get to decide whether you have any interest in learning more about the method, contributing to its improvement, or using it.
if you had a crystal ball and in january of this year you had known that some trading method would have three losing months and three winning months, but at the end of that time it would be up +5,000. your crystal ball has a little glitch and can’t tell you specifically which months will win and which will lose, so you would have to trade 'em all. would you? well, that’s why we collect data and do win/loss ratios, average loss versus average win, etc. because we presume and we hope that the future may be at least something like the past and we would very much like to have three losing months, three winning months, and +5,000 pips.
a final consideration. what is a loss of -1,200? if you had started trading with this method in july, it would just be a drawdown against previously accumulated equity and you would still be positive. if you just started at the beginning of this month, yes, you are down -1,200. that is, if you had traded all five pairs. forex is the most risk flexible opportunity anyone could ever imagine. first, you don’t have to trade the entire portfolio. second, a pip or a dollar can actually be anything you want it to be, from nothing on a demo account, to one cent, one dollar, a thousand dollars. if you are trading demo, you have lost nothing but time. if you are trading at .01, you started first of the month, and you traded all five pairs, you are down about $12.00. i went live at the beginning of the month with three pairs: g/j, a/u, and e/j, so am down about -750. but, how much is that in dollars? it is whatever i felt comfortable risking at the time.
the process for any new application is overview it, study any available performance data, try to replicate any available performance data, look at specific trades to get a feel for price action within the method’s structure, determine outcomes, demo trade, trade small and increase your risk only as your account builds. this is at least a one to three month process. you can see how different an approach like this is from, “don’t ask questions, buy when the arrow’s green and sell when it’s red, make quick and easy riches.”
