Post subject:  Error with strategy persistence
Hi, when i started a strategy with full persistence, I got the following error and strategy stops updating.

Code:
GUI exception System.ArgumentException: Item has already been added. Key in dictionary: '0 12/28/2018 09:28:16.271 Limit Sell'  Key being added: '0 12/28/2018 09:28:16.271 Limit Sell'
   at System.Collections.Hashtable.Insert(Object key, Object nvalue, Boolean add)
   at System.Collections.Specialized.OrderedDictionary.Add(Object key, Object value)
   at SmartQuant.Controls.Orders.OrderManagerWindow.ProcessExecutionCommand(ExecutionCommand executionCommand)
   at SmartQuant.Controls.Orders.OrderManagerWindow.UpdateGUI()
   at SmartQuant.Shared.TimerManager.timer_Tick(Object sender, EventArgs e)


How can I reset persistence after it is used (other than rename strategy)?

Thanks

Hello,
we know about this problem and solving it.
Actually, this problem is only on displaying (Order Manager window). Strategy works.

Additionally:
1)You can delete files orders.quant and portfolios.quant
2)You can delete saved portfolio/order series from scenario:
Code:
         if (deletePortfolios)
         {
            framework.PortfolioManager.Delete(name);
            framework.OrderManager.Delete(name);
         }

Thanks for your reply.

Yes, the error will make GUI chart stop updating.

BTW, I found that the sell side instrument strategy orders will not be recovered after solution restarted, even if they are shown in order manager. I am wondering if it is on purpose to do so?
