The problem is NOT the crash

Somethimes I have to stop my robot for various reasons (update, ..) But after restarting, onPositionClosed is not called.

Look at my example:

If run the robot, a position is opened.

When I close the position via cAlgo, onPositionClosed works correct.

When I stop the robot while a position is open and restart the robot and I close the position via cAlgo, onPositionClosed is not doing anything.

   [Robot]
    public class NewRobot : Robot
    {
           
           Position pos;
        protected override void OnStart()
        {
           if(Account.Positions.Count==0){
               Trade.CreateBuyMarketOrder(Symbol,10000);
           }else{
                   pos=Account.Positions[0];
           }
        }
        
       protected override void OnPositionOpened(Position openedPosition)
       {
               pos=openedPosition;        
       }
        
        protected override void OnPositionClosed(Position position)
        {
            Print("Netprofit: "+position.NetProfit);
        }

}

If you restart cAlgo or the Robot, it will not resume and remember any positions opened earlier. In order to modify specific positions created by one robot you may set the [label] property.
If you need additional help with the code let us know.

RE:

Hi,

let's say I have 5 positions within same robot

the internet connection goes down and then comes back up

I must restart robot

I see you mention in several posts different ways to remember positions... 

but I need help with actual code...

ie...

1.

i look to trade every x number of minutes based on 

protected override void OnPositionOpened(Position openedPosition)
        {
            lastExecutedTime = Server.Time;

so how would I know what lastExecutedTime = ? (code please)

2.

if i have a max position size of 10 and I have 5 befor the disconnect how do I tell the robot this on restart? (code please)

thanks!

After you restart the robot all variables will be reset. The only information you can retrieve is open position information. Therefore you can use EntryTime instead. In order to find the positions of a specific robot you may assign Labels to these positions when the trade Requests are sent. Then retrieve the positions by their Label and find their entry time. The latest position will have the latest entry time. If the position closes the entry time will not be available.

        /// <summary>
        /// If there is no position, returns 01/01/0001 00:00:00	
        /// </summary>
        protected DateTime LastExecutedTime
        {
            get
            {
                Position lastOrDefault = Account.Positions.LastOrDefault(position => position.Label == RobotLabel);
                return lastOrDefault != null ? lastOrDefault.EntryTime : new DateTime();
            }
        }

the Linq namespace is required for the above code

using System.Linq;

 The same as above, use Labels and count how many positions have the Label that is set with this robot.
