We cannot provide programming help.

But what we can say is definitively there is a problem on your side where messages are not being sent and therefore not received by Sierra Chart:
DTC client #59. Sample Application. | No heartbeat received after 1m 20s. Closing network socket. | 2017-12-02 10:40:48

Make sure there is a null terminator after each one. If there is not a null terminator, then that can lead to a problem where the messages just never get processed.

Also we see this:

String marketDataRequestCL = "{\"Type\":101,\"RequestAction\":\"SUBSCRIBE\",\"SymbolID\":1,\"Symbol\":\"CLF8\", \"Exchange\":\"NYMEX\"}";

In regards to the Exchange field, that is not needed. Refer to the Notes section here about this:
