Trouble testing trading strategies in MT4...

Okay guys :-) I decided i want to test some of the strategies i had in my mind and i opened up my MT4 and started the "Strategy tester"

I donwnloaded the M1 database from F2 on the currency pair i wanted to test and after i configured everything i first optimized the EA and then i decided to only test what results it will give.

I like using the visual mode in the software... And here comes my problem... The last test i did was from 2011.01.01 to 2014.06.20

What happens is... The EA works perfectly the first 20-30 days at the begining of the timeframe i use for the test... The timeframe could be different but the EA only works in the test of around 30 days. After that it doesn't take any trades for the remaining time (which the last time is 3 years and a half or something like that) and the test becomes pointless.

How can i test my EA properly or how do i fix this problem so i can test it in MT4. I tried testing on other timeframes but the problem remains...

some errors (see experts/journal-tab)?
or attached the ea (mql4-file), maybe there is a problem with the logics

Well there is a row that says 50 something errors blah-blah, but i can't access these erros and i can't see what these errors are :-) i can attach the EA if you want to check it out - no problem. I usually test on H1 timeframe but now i started a daily test for the thingy.

Could there be a problem with the software?

P.S. i am attaching the EA now. If you want to check the code, be my guest.





All help is appreciated and welcome!

try your tests starting at different dates, different months, years, do you get the same result? still only good for 30 days?

if so it sounds like your code is date dependent and when it comes to the same day in the next month it has problems.

Hm... well if someone could check the code for errors i would be super happy... At the same time i will try testing on different periods different levels of SL and TP and if i have enough time i will test on other currencies.

:-))

I have downloaded it but atm no time to have a look. I will check it maybe tomorrow or when I have time ...

runs ok for me, results no good but it does trade.
have you checked your data?

Works fine with me only on D1... It it is on lower it does only 20-30 days... no matter the timeframe or anything else...

As for the D1, yes it doesn't give good results - wipes the account really...

I'll play around with the SL and TP - im having the feeling the SL is too narrow for D1 45 tp and 45 sl... i guess it is not enough.. I'll even test it a few times without stops...

Still i am confused as to why it doesn't work on H1 properly..

backtesting from 2012-01-01 to 2012-05-01 on h1 with the default settings: no errors, but not profitable, so I do not know what the problem is. maybe missing/bad backtesting data?

To be honest i don't really know :-D... i don't know how to get more accurate and better backtesting data then downloading it from MT4...

Okay... I tested another EA that i had (not mine, i downloaded it from a thread in this forum) I ran it on H1 and after the first 2-3 months it stops trading agian.... I guess the problem is in the data or the software... No idea


.... Anything under D1 stops trading. Doesn't matter what period or what EA it is. Doesn't matter if it wipes out the account in the time it trades... It just stops trading

Hello again....
I tested this:



On H4... it took 13 trades and stopped ... and we are talking about a period of 2011.01.01 to 2014.06.20

I don't know what is wrong with my terminal, but this is really funny :-D

It is a PSAR based EA.

pls. use google or the forumsearch to find tutorials how to download and install tickdata for backtesting ...

btw, your candlestick-ea only works if the symbol-name is "EURUSD", so if the broker uses suffixes the ea will not work correct.
I did some mods/changes (but will not do mor on this ea) ...
