You can modify StarterConsumer in RFA C++ package to subscribe to Time & Sales RICs, such as tIBM.N.

To request a Time & Sales RIC, the application needs to use a snapshot request.

rfa::common::Handle* sendItemRequest(
   const rfa::common::RFA_String& itemName, 
   const rfa::common::RFA_String& serviceName,
   rfa::common::UInt8 indicationMask = 0,
   rfa::common::UInt8 msgModelType = rfa::rdm::MMT_MARKET_PRICE,
   //  rfa::common::Int32 interType = rfa::message::ReqMsg::InitialImageFlag | rfa::message::ReqMsg::InterestAfterRefreshFlag);
   rfa::common::Int32 interType = rfa::message::ReqMsg::InitialImageFlag);

The Time & Sales data is available in SEG_TEXT field which represents:

The 255-byte text field which can contain up to four log entries. There are embedded New Line control characters within this field to assist in displaying the log information.

To retrieve the next log segment, the application must subscribe to a RIC in NEXT_LR field.

if(respMsg.getHintMask() & RespMsg::PayloadFlag)
	{
	//	_pDecoder->decodeData(respMsg.getPayload());
		const rfa::common::Data& data = respMsg.getPayload();


		if (!data.isBlank())
		{
			if (data.getDataType() == FieldListEnum){
				const rfa::data::FieldList& input = static_cast<const rfa::data::FieldList&>(data);
				FieldEntry fEntry;


				if (input.find(258, DataBuffer::StringRMTESEnum, fEntry)){ //SEG_TEXT
					const rfa::common::Data& data = fEntry.getData(DataBuffer::StringRMTESEnum);
					if (!data.isBlank())
					{
						const DataBuffer& dataBuf = static_cast<const DataBuffer&>(data);
						printf("%s\n", dataBuf.getAsString().c_str());


					}
				}
				if (input.find(238, DataBuffer::StringAsciiEnum, fEntry)){ //NEXT_LR


					const rfa::common::Data& data = fEntry.getData(DataBuffer::StringAsciiEnum);
					if (!data.isBlank())
					{
						const DataBuffer& dataBuf = static_cast<const DataBuffer&>(data);
						printf("NEXT_LR: %s\n", dataBuf.getAsString().c_str());
						sendItemRequest(dataBuf.getAsString(), _cfgVars.serviceName);
					}


				}
			}
		}
	}

The output of the application looks like:
