Hi, first of all many thanks for this great API and platform. I've been back-testing my strategy in the last couple of weeks without any problem suddenly it stopped working today. I got the exception below:

01-Dec-2012 17:01:51 com.dukascopy.charts.data.datacache.business.LoadLastTicksAction sendTicks
WARNING: No ticks for instrument EUR/USD
01-Dec-2012 17:01:51 com.dukascopy.charts.data.datacache.LoadDataAction run

...

Looks like data feed server sending corrupted data. I cleaned my cache folder and tried again but I keep getting the exception above.

I hope this is the correct thread to ask this question. Forgive me If it is not I am a newbie in this forum

Thanks.

Hi Skynet,

I too have been experiencing this problem and hadn't yet gotten around to posting the bug, thanks for posting it.

Hello Support and all,

I also experience similar problem this morning. Running live client against demo server I get following series of exceptions

2012-12-06 08:28:25.747 ERROR IntraperiodCandlesGenerator - Request for in-progress candle data for instrument [EUR/USD] period [null] side [null] to [2012.12.06 07:26:06 324] attempt [1] timed out

The application ran correctly until yesterday and only once this morning. Please investigate, thanks in advance

Update: it seemed to be a temporary problem. From around 10 am CET it worked correctly again.
