Hi, I have a websocket client that I use for all my exchange market data. It is a c++ client based on websocketscpp. #[live.tradovateapi.com](http://live.tradovateapi.com) for Live only functionality. #[demo.tradovateapi.com](http://demo.tradovateapi.com) for simulation engine. #[md.tradovateapi.com](http://md.tradovateapi.com) and for a market data feed. are available. I am only paper trading (in DEV) so Im connecting to [demo.tradovateapi.com](http://demo.tradovateapi.com) • I can successfully issue my request for token using username, secret , cid etc. This is done via a CURL using a C++ request and the response gives me an accessToken, marketAccessToke as well as these other JSON fields ,“hasLive”:false,“outdatedTaC”:false,“hasFunded”:false,“hasMarketData”:true,“outdatedSentimentPolicy”:true} • Then I can successfully establish a connection to wss://demo.tradovateapi.com/v1/websocket $ ./client wss://demo.tradovateapi.com/v1/websocket/md/subscribeQuote Successfully connected to: wss://demo.tradovateapi.com/v1/websocket/md/subscribeQuote Running websocket: wss://demo.tradovateapi.com/v1/websocket/md/subscribeQuote [2024-09-29 19:17:09] [connect] Successful connection [2024-09-29 19:17:09] [connect] WebSocket Connection 34.117.68.229:443 v-2 “WebSocket++/0.8.2” /v1/websocket/md/subscribeQuote 101 Note: I do not use the accessToken or mdAccessToken to connect. I think this is the source of error but I’m not sure. However I know the wss connection is ok because I get a response back; Connection is opened ok as my CURL callback receives o” . Note after this I get nothing back, no heartbeats, no “server disconnecting session” etc. (i.e. I get no ‘h’, ‘a’ or ‘c’ messages back from tradovate) • I then try to subscribe to GOOG with websockets (websocketscpp). I send the follow over the websocket connection opened above (same client process that obtained the tokens) {“id”:“0231242342232”,“method”:“subscribe”,“symbol”:“GOOG”} I also try with just symbol and id (always uuid) {“id”:“45646546”, symbol”:“GOOG”} However I cannot subscribe! Nothing is coming back I know today is Sunday and market is closed but this is consistently failing. Can you see the fault? ./client wss://md.tradovateapi.com/v1/websocket/md/subscribeQuote g++ -I. -I/home/gjw/websocketpp -std=c++2a -o client websockets.cpp main.cpp -lssl -lcrypto -lcurl -ljsoncpp -lpthread -lwebsockets gjw@LUNA056:~/tradovate\_abundance/GRAHAMS$ ./client wss://demo.tradovateapi.com/v1/websocket/md/SubscribeQuote Received: {“accessToken”:“XXXXXXXXXXXXXXXXXXXXXXXXX”,“mdAccessToken”:“YYYYYYYYYYYYYYY”,“expirationTime”:“2024-09-29T18:31:05.785Z”,“userStatus”:“Active”,“userId”:2854187,“name”:“Google:102927092604715150178”,“hasLive”:false,“outdatedTaC”:false,“hasFunded”:false,“hasMarketData”:true,“outdatedSentimentPolicy”:true} Running websocket: wss://demo.tradovateapi.com/v1/websocket/md/subscribeQuote [2024-09-29 19:17:09] [connect] Successful connection [2024-09-29 19:17:09] [connect] WebSocket Connection 34.117.68.229:443 v-2 “WebSocket++/0.8.2” /v1/websocket/md/subscribeQuote 101 Received: o --------------------------\> GREAT - got control character ‘o’ back from tradovate Sending following subscription symbol message: {“id”:“023991242342232”,“symbol”:“GOOG”} Sent OK!
