Storing positions

2017-11-06T22:30:01Z

I need to store my positions so that when my application starts up it can load the existing positions. The code I use is:


var dataPath = @"Data\" + _connectorAccount.AccountName;
_entityRegistry = new CsvEntityRegistry(dataPath);
_storageRegistry = new StorageRegistry
{
    DefaultDrive = new LocalMarketDataDrive(dataPath)
};

_connector.InitializeStorage(_entityRegistry, _storageRegistry);
_entityRegistry.Init();

_connector.StorageAdapter.DaysLoad = DateTime.Now.Subtract(_connectorAccount.StartTrading.Value);

_connector.StorageAdapter.Format = StorageFormats.Csv;
_connector.StorageAdapter.Load();

The problem is that when I connect to TWS, I get the following error message:

Message 'Connect,T(L)=2017/11/06 21:25:31.278,Error=At least one connection should be made.' caused processing error.

with inner exception message:

The given key was not present in the dictionary.

and inner exception stack trace:
