I sometimes catch exception in this: Code: DateTime temp = dt1; while (temp + new TimeSpan(1, 0, 0, 0) < dt2) { DataSimulator.DateTime1 = temp; DataSimulator.DateTime2 = temp + new TimeSpan(1, 0, 0, 0); temp += new TimeSpan(1, 0, 0, 0); try { StartBacktest(); } catch (Exception ex) { Console.WriteLine(ex.ToString()); } } The exception says: Code: System.IO.EndOfStreamException: Unable to read beyond the end of the stream。 in System.IO.__Error.EndOfFile() in System.IO.BinaryReader.FillBuffer(Int32 numBytes) in System.IO.BinaryReader.ReadInt64() in SmartQuant.NetDataFile_.yUQPMJFLyB(NetDataSeries , Int64 , Boolean ) in SmartQuant.NetDataSeries.GetIndex(DateTime dateTime, SearchOption option) in Jps11lpriQ5NSp0Ku8j.BCDLl4pmi6Ds517tFby..ctor(IDataSeries , DateTime , DateTime , EventQueue , DataProcessor ) in SmartQuant.DataSimulator.OnConnected() in SmartQuant.Provider.set_Status(ProviderStatus value) in SmartQuant.DataSimulator.Connect() in SmartQuant.Strategy.cSXFdr8iit(Strategy , InstrumentList , Int32 ) in SmartQuant.InstrumentStrategy.f9lUUbMwQ9() in SmartQuant.StrategyManager.StartStrategy(Strategy strategy, StrategyMode mode) in SmartQuant.Scenario.StartStrategy(StrategyMode mode) in SmartQuant.Scenario.StartBacktest() in OpenQuant.Backtest.Run() in C:\Users\lenovo\Desktop\MySampleProviders\All_Providers\OpenQuantPlugins\Strategy_Reversal\Backtest\Scenario.cs: line 102 And the file data.quant never changed even after closing FileServer.exe How can I fix this exception? |

Hi, Please, reproduce this problem in the default strategy (with default data) from the OQ2014 installation and send us a modified version. This will allow us to debug your situation. |
