I'm confused with backtesting
« on: May 11, 2009, 02:11:03 AM »
I am using broker FXDD. Eur/chf with FT 45Pro and Eur/gbp with FT45Pro. I am also using Eur/Usd with MD. All three on one set of three charts. Have tried back testing all the pairs with their respective EA's. Always clear the journal before downloading  and I recalculate. Still the download is full of errors and I cannot do a backrest on any of the pairs. I wonder why?

What is forward testing. Anything like a demo account? Is it worthwhile doing? If so how?

There are a few reasons:-

Did you download the historical data? Go to 'tools'--->'history center' and find the currency pair you want to use and download the data. Download M1 data.

Did you enter in your key into the EA's? Also on Megadroid you will need to turn off the auto-GMT and select it manually, auto-gmt does not work for backtesting.

Failing the above, if you let me know what the error messages are i'll see if i can help further.

A forward test means just setting the robot up to trade and letting it trade on a demo (or live perhaps). We are all doing forward tests of sorts when we continue trading :-).

Regarding forward testing . I saw the new section on forward testing and figured it out. I have noticed that when a forward test ( and even a back test) provides good results there are a plethora of questions asking for settings and broker. I ask myself the same question. Why can't these questions be answered when the post of the back test/forward test are uploaded? That is if the author is proud of them. They would be a lot more informative that way.

I'll try the back testing with your suggestions and get back.

Finally got the backtesting to work. Here are  my results using 4 EA's.
All tests were two year with EA's set to default and using broker FXDD.
I am brand new in this game, but unless the back testing is grossly underestimating a live account I cannot see how any of the EA's live up to their hype. (Double your money in a month.Hah!)
FT4  EURCHF M15       Finish amount 1900+
FT4 EURGBP M15        Finish amount 2200+
MD EURUSD H1          Finish amount 2300+
Pipsleader EURUSD HI Finish amount 2100+
and the winner is
ACG EURUSD M5       Finish amount 6193

Could it be the broker? What ain't I doing? All of the above in demo accounts have not traded in the past six days with the same settings I used for the back test. I get smiley's on all.

It's probably the risk levels not returning to you the results they show on the homepage. I know for FAPTurbo anyway, you have to set the risk very high to copy what they are doing. I have a (live) account here: http://donnaforexhr.mt4stats.com which has doubled in 8 days trading only FAPTurbo... so it's very possible, but so also is wiping out your account. The risk i used there, especially at the beginning was getting on for 100% of my balance per trade. if you keep watching the account you might see it blow up- i am testing this account to the extreme and will be increasing the lot size again shortly to 0.2 lots. I think my chances of making it through the month of May are pretty low.

Dear Donna,

I'm confused with your account on http://donnaforexhr.mt4stats.com/. It's very amazing! Anyway, is it possible to open 0.1 lot of EURGBP and EURCHF with only $100? I once tried it on my demo account and no trades at all. And also, I noticed that Fap Turbo opened another 0.1 lot on your account while there's already one open position. I don't think the margin is enough for that. I'm a newbie and not good at calculating, can you explain?

856121   2009.05.05 00:24   sell   0.10   eurchf   1.5102   1.5264   1.5052   2009.05.05 03:14   1.5102   0.00   0.00   0.00   0.00
856163   2009.05.05 00:28   buy   0.10   eurgbp   0.8925   0.8772   0.8985   2009.05.05 01:24   0.8930   0.00   0.00   0.00   7.51

Also, some of my trading during May are in minus result (loss). I don't understand, why using the same EA gives us different results? My stat is http://nogreed.mt4stats.com/
I'm using FX Open with fixed spread of 3.

Thanks for your help :-)

Regards,
Yen

Actually, there wasn't enough margin on my account to maintain an open trade in the beginning with only $100. It kept flashing me red warnings and my margin dipped to below 80% (not all brokers close out positions immediately if you run below the margin requirement). The broker won't allow me to trade any size smaller though. I think the leverage on this account is fairly high too, although i cannot remember exactly what it is.

Don't speak too soon about this account, i have a trade open right now in some drawdown which is about equal to all the gains i have had thus far!
