You need to pass instrument tokens as numbers,not as string.

narayanan

Hi Rakesh,
I am subscribing with numbers only. You can see UInt32.
_ticker.Subscribe(Tokens: new UInt32[] { _stockInput.InstrToken });
_ticker.SetMode(Tokens: new UInt32[] { _stockInput.InstrToken }, Mode: Constants.MODE_QUOTE);

I suspect the check need to be handled from your side on Full and ltp being empty.

narayanan

I just cross verified with subscribing all mode Mode: Constants.
The issue is not occurring. When ticker disconnected resubscribing happens automatically as said in the above log. Since i have not used Full and LTP and it is being empty. We are getting Error Parsing Instrument Tokens.

Please add the check for empty string on your end and handle gracefully to avoid ticker disconnection.

After below Work around from my end No issue occurs.
_ticker.Subscribe(Tokens: new UInt32[] { 11717378 });
_ticker.SetMode(Tokens: new UInt32[] { 11717378 }, Mode: Constants.MODE_LTP);
_ticker.Subscribe(Tokens: new UInt32[] { 11719682 });
_ticker.SetMode(Tokens: new UInt32[] { 11719682 }, Mode: Constants.MODE_FULL);
_ticker.Subscribe(Tokens: new UInt32[] { _stockInput.InstrToken });
_ticker.SetMode(Tokens: new UInt32[] { _stockInput.InstrToken }, Mode: Constants.MODE_QUOTE);
