Reconnect Terminal

[Marian Mesbah]

Dear Roman,

I was trying to test my application behavior in case of terminal disconnection by stopping the terminal from Terminal Server Dashboard and i faced 2 scenarios.

- In first scenario i used strategy.connect in the application start, then run timers that retrieve candles data, when i stop  the terminal, the nj4x will automatically handle the terminal re-connection & will keep retrieving the data stream normally.

- in second scenario i used SetBulkTickListener before the strategy.connect so i can retrieve the tick data along with the timers that handles the candles, when i disconnect the terminal, i notice that in the dashboard journal the automatic re-connection try to connect more than one terminal instance & the tick data retrieval stop.

also if i tried to rerun the timers i receive the following error "An exception of type 'Terminal connection not initialized -> No connection to the trade server" 

Please advise 

Thanks

There was a bug in reconnection mechanism, should be fixed now. Please update to the latest (2.7.1) version of API.

Thanks Roman, its fixed in the new version but the SetBulkTickListener stop retrieving the current ticks, i tried to run a timer to check the connection IsConnectedToTerminal() every second & when connected i call again SetBulkTickListener but it didn't work.

Please advise

It is strange, because BTL reconnects and continue getting ticks in my tests. I will prepare example for you later..

Dear Roman,

Please share with me the re-connection tick example as soon as you can.

Thanks

Here you are

        private class CustomInitStrategy : Strategy

        {

            public override void Init()

            {

                base.Init();

                //turn off symbols from MW

                foreach (var symbol in Symbols) SymbolSelect(symbol, false);

                //turn on required symbols at Market Watch to get their ticks

                foreach (var s in new[] { "EURUSD", "GBPUSD" }) SymbolSelect(s, true);

            }

        }

        private static void TestBTLReconnect()

        {

            var terminalServerHost = "127.0.0.1";

            var terminalServerPort = 7788;

            string brokerName = "demo1-amsterdam.fxpro.com";

            string account = "6796186";

            string password = "dpkk4hg";

            //

            var mt4 = new CustomInitStrategy();

            //

            bool showTicks = false;

            mt4.SetBulkTickListener((ticks, connection) =>

            {

                foreach (var tick in ticks)

                {

                    if (showTicks)

                    {

                        Console.WriteLine($"{tick.Symbol} {tick.Time} {tick.Ask} {tick.Bid}");

                    }
