yousky · #11 (**permalink**) 03-09-2006, 11:04 PM

Here the new version one without this bug

I hope.

http://yousky.free.fr/phpBB2/viewtopic.php?t=87

For beerhunter and other users

like mention in the version informations, I've not converting all functions from MQL2 because like SetIndexValue, GetIndexValue, ... I don't know how to convert them in MQL4 ???

If some one know the good MQL4 code for those functions, give me

and I will implemente them in next version.

Thanks.

With a little work you can convert mt2 int mt4 with yousky's tool, the attached was converted with his beta3 version, yousky is fixing a few bugs and will have beta4 out soon. But while you are waiting and you had some interesting ea's in mt3 ty using his tool to convert them.

GReat tool yousky thanks

None of the coverters works, I have tried them all. I get errors in the bottom window.

Fred,

you have to take the time to fix the errors, the converter does most of the work, but will leave in code that is not used. That code must be deleted, and there is some code in mt3 that is not referenced, that also must be deleted or changed, then your ea will work.

The converter does 95% of the work, you must do the rest.

Big thanks Foreverold

for your help

.

I have to say that somes EA are very bad coded, for exemple in "while" syntax, or "if" you can see some times one or 2 brakets that are not used for exemple:

Quote:

if (StopLoss > 0)) then

Here you can see one open braket and 2 close bratkets, in MQL2 the compilator don't give any error, but in MQL4 theres errors.

So

Mql2Mq4 works an EA good coded for other you have to make manual changes.

I will improve my tool, so tell me what is not working and I hope correct them.

Thanks bye bye

hi yousky..

Many thanks for this great tool

I already converted dayimpuls mql for mq4, but I dont understand why it does not give the same value...

Take a look, please...

I think that it is all good but I dont understand this difference of values

many thx

Hi hellkas,

I've tried to convert your MQL2 code in MQ4, and I have the same value for the "per" variable. It was your problem no ?

You have post all the code of your DayImpuls ?

Hello hellkas,

So your problem is that you don't have the same result after convertion on MT3 and MT4 ? Can you post your MT3 version and I will test it afer converting.

Thanks
