Hi, I've been trying to import some data that I downloaded from Dukascopy, but appear to be getting some errors. The data is in 1 minute intervals, but only shows up as daily bars when imported. A sample of the data is attached.

Thanks,
Chris

Sorry but Forex Tester does not support such data format, i'll try to find a programmer who will be able to create data converter to translate data into FT format

Please see incompatibilities of these data below:

1) Date format should be one of the followng: YYYYMMDD, DDMMYYYY, MMDDYYYY. YYMMDD, DDMMYY, MMDDYY

2) Time format should be HHMMSS

I've developed a full-bodied system in FT which I want to trade live. I opened a Dukascopy account and converted my "execution" module to JForex -- but the rest of my system (multiple modules for optimizing) is in FT. Things have worked out pretty well, but there are some differences between execuction in FT and the JForex platform. So, I converted Dukascopy data to load into FT to eliminate that variable from the problem.

I think the data conversion went well (a java program I wrote), but when I run my system and compare 30 minute bar charts between FT and JForex, there are some significant differences. Also, focusing on a single bar (2007-09-07 02:30), the one produced in FT doesn't seem to match the OHLC within that 30 minute period... but the JForex bar seems to reflect the data.

I'm attaching two annotated screen shots. Can you please tell me if I have a data conversion problem? Thank you.

Hello,

Pleae check if you have same M1 bars in JForex and FT in History Mode than check if you have same M1 bars in Testing Mode and let us know.

I will still try your suggeston regarding 1min data. But for now, I should say that I changed my conversion program to round volume to an integer (got rid of the decimal point) and the results are 98% better. There are still some wicks on the candles that are different, but the candle bodies now look the same without all of the gaps I was getting.
