I'm sending a heartbeat(ping) back to the server - Sierra logs confirm that - but it doesn't register as a heartbeat and times out after 60 sec. Data flows to the client fine. I have the null terminator at the end of the json as well. (PHP) $msg = '{"Type":3}'."\0"; $conn2->send($msg); DTC Protocol server | Incoming connection from 10.70.70.72. | 2022-12-16 05:23:09.976 DTC client #37. 10.70.70.72 (4) | Creating socket. | 2022-12-16 05:23:09.979 DTC client #37. 10.70.70.72 (4) | New receive buffer size: 262144 | 2022-12-16 05:23:09.979 DTC client #37. 10.70.70.72 (4) | Allocated send buffers: 32 of 131072 bytes. | 2022-12-16 05:23:09.980 WSServer | DTC client #37. 10.70.70.72 (4) | Start Server | 2022-12-16 05:23:09.981 WSServer | DTC client #37. 10.70.70.72 (4) | Switch to HANDSHAKE | 2022-12-16 05:23:09.981 WSServer | DTC client #37. 10.70.70.72 (4) | Switch to READY_DATA | 2022-12-16 05:23:09.981 WSServer | DTC client #37. 10.70.70.72 (4) | Response HANDSHAKE with status code 101 | 2022-12-16 05:23:09.981 JSON data: {"Type":1,"HeartbeatIntervalInSeconds":5,"TradeMode":1,"Username": xxx"Password": "xxx","ClientName":"trades"} | 2022-12-16 05:23:09.985 DTC client #37. 10.70.70.72 | Requested heartbeat interval: 5 | 2022-12-16 05:23:09.987 DTC client #37. trades. 10.70.70.72 | Received logon request. | 2022-12-16 05:23:09.987 DTC client #37. trades. 10.70.70.72 | Sent successful Logon response message to client.

$ping = new Frame('', true, Frame::OP_PING); $conn2->send($ping); That fixed it. Thank you. No more disconnects. Follow up question. I'm sending 300, 601, 400 and 305 messages yet I'm not getting a response on most of the requests. Position and Balance request come in only if there is an open position and the price changes to affect the open P&L. Date Time Of Last Edit: 2022-12-22 02:36:24

We do not know from memory, what those messages are. Best to give the names of them. Did you also enable Global Settings >> Sierra Chart Server Settings >> DTC Protocol Server >> Allow Trading.

My mistake again - was sending \n instead of \0 for termination. All issues resolved. No bugs with sierra :)

Hello, I am trying to implement my necessary DTC Communication in Perl. And I am failed on the missing heartbeat within 20 seconds. $ping = new Frame('', true, Frame::OP_PING); I expect the $PING is a JSON Format Value, what content is it? If I would write it be text, what do I have to send as Heartbeat? Thanks best regards Carsten |

I add something during initiation of the connection: connection init

We definitely do not recommend a heartbeat interval of 120 seconds. It should be about 20 seconds. First resolve that. Sierra Chart Support - Engineering Level Your definitive source for support.

This is only for testing if my send JSON does change anything. Yes, of I will use 5 sec instead.

5 or 0 sec. It is not important to me.

Hello, could it be enough to send the following JSON Frame? {type:3}\0
I have not tested until now, but I read in the Documentation: There are no required member fields to set in this message. The purpose of the HEARTBEAT message is so that the Client or the Server can determine whether the other side is still connected.
But this is the starting point of this thread? Thanks for your feedback regards |

Yes: Or can I send the heartbeart regularly, like I did up to now?
Now that we look more closely at this log the problem is not the heartbeat but the websocket ping: WSServer | DTC client #10. 192.168.17.201 (1) | Timeout waiting for ping message from client. | 2023-01-25 12:57:07.277 Sierra Chart Support - Engineering Level Your definitive source for support.

Yes it should be: could it be enough to send the following JSON Frame?

Do I have to send an additional Websocket ping to the DTC Server?

Yes that is certainly required by the websocket protocol.

Than the heartbeat Type 3 is not necessary for a Websocket connection, only a Websocket ping?

Do you have a documentation on what is required by the DTC Server. Now I send a ping every 5 seconds. Now I will be disconnected a bit latest. Now with the Message the PONG Message is missing. regards |

Hello, Actually I send every five seconds a ping and a pong and the Type 3 Message and this seams to work. Up to now it is not nice, but it works for the moment. Do you have documentation on the WebSocket Communication? PIng and Pong requirement? thanks |

Regarding post #20 you need both. You need the DTC protocol heartbeat message to be sent about every 20 seconds and you need the websocket Ping message according to the websocket specifications which we do not publish.
