Dear all kind classmates,someone can help me convert the attached MT4 strategy into java?
The best wishes and thanks in ton to you!!!!

What problems have you faced when trying to convert it with the converter?

The strategy works fine in MT4. Actually, I don`t see specific errors when convert it to Java. But when I local run the strategy in JForex, there is no orders open as expect. I test the strategy in JForex, no result either.

Hi,

You could give it a try to use this. This is a tool that copies trades from Metatrader to JForex.
I know it is not the solution for the issues with the converted strategy, but at lease it can be a workaround.

The MT4 strategy seems work in JForex after conversion. I can see open orders and close orders during demo running in JForex. But I don`t know why it basically don`t open orders when I test it in JForex Historical tester. Does JForex Historical tester not support MT4 converted strategy testing? Anyone know about it or tried before?

There should be no 'restriction' about the Historical Tester. So the converted strategy should work fine in the tester as well.

What might be the case is that there is something in the EA/strategy that is behaving differently on a demo account compared to the tester. For example, if you want to get the current time, it is always 'in the past' on a demo account. Whenever you call the function to get the time, the returned value will be a couple of milliseconds behind.
If you execute the same code in the tester, and suppose you test between 2012-01-01 and 2013-01-01, the current time (2015-01-19) will be a date in the future (compared to 2012 and 2013).
If there is anything on the code that uses such thing (makes decision on date/time), there is a chance that it is going wrong in the tester.
And this is not only involving the current time, but for example the date+time of the last bar/tick for an instrument.

I haven't looked on the code, so I cannot say that this is the problem. This is just a possibility.
I suggest further on to create a topic in here, so Support is aware of your issues. And they can probably help to get you further.
