I need EET candle values (OHLC) for a Visual JForex strategy. I could "hack" the java code in JForex adding

private JFTimeZone myJFTimeZone = JFTimeZone.EET;
private Period myPeriod = Period.createCustomPeriod(Unit.Day,1,myJFTimeZone);

and modifying the references: from Period.DAILY to myPeriod

It works for Get Historical Candle blocks, but when trying to use values from the last unfinished EET daily bar an exception stops the strategy.

What do you suggest?

Hi there,

As you noticed VJF works with GMT but we'll check the tech team regarding your concern.
Can you send this strategy so that we can check this error ?

Thanks

Thanks for your answer.

I've prepared a simple example to reproduce the exception:

In Visual JForex I've setup a strategy retrieving the last finished daily candle (shift 1) for the default instrument, and retrieving the unfinished daily candle too (shift 0).

Image

Then I've modified the java code to print the open value of both candles in the console (mod1). It runs ok in JForex.

The second modification was to change the timezone of the daily candles to EET and then printing only the last finished EET daily candle open value (mod2). It runs ok in JForex.

The third modification was to printing both candles: the last finished EET daily candle open value and the unfinished EET daily candle open too (mod3). It stops with an exception in JForex.

Please find enclosed the code in the attached file.

Best regards

Francisco

Hi there,

it's strange because when I test the file you sent I have no exceptions with the values printed normally. No exception and no modifications made ..
here is the print:
2017-08-03 13:37:50 _LastFinishedCandle Open:1.18014
2017-08-03 13:37:50 _UnfinishedCandle Open:1.18555
2017-08-03 13:37:40 _LastFinishedCandle Open:1.18014
2017-08-03 13:37:40 _UnfinishedCandle Open:1.18555

Thanks for your help:

That's weird!

I'm using the same version of jforex (3.2.13) under windows 8.1.

I still have the problem with exceptions using EET unfinished candles in my main laptop (Windows 8.1) and my VPS (Windows Server 2008 R2), but it works in my secondary laptop (Windows 10 home)

I've upgraded my VPS from Windows Server 2008 to Windows Server 2012, and now the test program works well.

If i add:
private JFTimeZone myJFTimeZone = JFTimeZone.EET;
private Period myPeriod = Period.createCustomPeriod(Unit.Day,1,myJFTimeZone);
and
modify the references in gethistoricalcandles and indicators: from Period.DAILY to myPeriod

the strategy does not open any trade during backtests.
Help ! I need 5 daily candle during the week

Unfortunately after upgrading my main laptop from Windows 8.1 to Windows 10 home, the test program still has the same problem.
