As you see, not only summary message(F), but also update message(Q), the time info for some data is invalid(99:99:99.xxx), that's the reason why my program got stuck. Now I have ignored the data like that.
1. Well I already know where the problem is. The socket connection is ok, our application also get the data when opening. But what made me confused was the time received. For keeping ascending time sequence of every contract, our application will ignore the data of which the time is older than the one last received, so if the application received a wrong data time at the beginning of opening, the time which is, for example, two days later , the application would accept the data and update the last received time to two days later, then it will reject all the normal data, cauze the time is older than the last updated. That's why I mistook no data on the connection.
The following is the time I got (GMT+8) [34972:35016:1129/090000:VERBOSE3:iqfeed_md.cpp(34)] OrigSndTm=2018-12-02 17:40:39.000, OrigSendingTimeInNano=1543743639000000000, SecurityID=22549, BidPrice=0, BidSize=0, AskPrice=0, AskSize=0, LastPrice=1370, LastSize=2, msgSeqID=1 [34972:35016:1129/090000:VERBOSE3:iqfeed_md.cpp(34)] OrigSndTm=2018-12-02 17:40:39.000, OrigSendingTimeInNano=1543743639000000000, SecurityID=22549, BidPrice=0, BidSize=0, AskPrice=1455, AskSize=10, LastPrice=1370, LastSize=2, msgSeqID=2 [34972:35016:1129/090000:VERBOSE3:iqfeed_md.cpp(34)] OrigSndTm=2018-12-01 17:40:39.000, OrigSendingTimeInNano=1543657239000000000, SecurityID=22550, BidPrice=0, BidSize=0, AskPrice=0, AskSize=0, LastPrice=1400, LastSize=0, msgSeqID=1 [34972:35016:1129/090000:VERBOSE3:iqfeed_md.cpp(34)] OrigSndTm=2018-12-01 17:40:39.000, OrigSendingTimeInNano=1543657239000000000, SecurityID=22550, BidPrice=0, BidSize=0, AskPrice=1450, AskSize=10, LastPrice=1400, LastSize=0, msgSeqID=2 [34972:35016:1129/090000:VERBOSE3:iqfeed_md.cpp(34)] OrigSndTm=2018-12-02 17:40:39.000, OrigSendingTimeInNano=1543743639000000000, SecurityID=22544, BidPrice=1936, BidSize=12, AskPrice=0, AskSize=0, LastPrice=1937.5, LastSize=5146, msgSeqID=1 [34972:35016:1129/090000:VERBOSE3:iqfeed_md.cpp(34)] OrigSndTm=2018-12-02 17:40:39.000, OrigSendingTimeInNano=1543743639000000000, SecurityID=22543, BidPrice=6244.5, BidSize=1, AskPrice=0, AskSize=0, LastPrice=6251.5, LastSize=12183, msgSeqID=1 [34972:35016:1129/090000:VERBOSE3:iqfeed_md.cpp(34)] OrigSndTm=2018-12-02 17:40:39.000, OrigSendingTimeInNano=1543743639000000000, SecurityID=22548, BidPrice=1930, BidSize=1, AskPrice=0, AskSize=0, LastPrice=1925, LastSize=2510, msgSeqID=1 [34972:35016:1129/090000:VERBOSE3:iqfeed_md.cpp(34)] OrigSndTm=2018-12-02 17:40:39.000, OrigSendingTimeInNano=1543743639000000000, SecurityID=22546, BidPrice=10865, BidSize=1, AskPrice=0, AskSize=0, LastPrice=10865, LastSize=3970, msgSeqID=1 [34972:35016:1129/090000:VERBOSE3:iqfeed_md.cpp(34)] OrigSndTm=2018-12-02 17:40:39.000, OrigSendingTimeInNano=1543743639000000000, SecurityID=22547, BidPrice=18260, BidSize=4, AskPrice=0, AskSize=0, LastPrice=18380, LastSize=448, msgSeqID=1 [34972:35016:1129/090000:VERBOSE3:iqfeed_md.cpp(34)] OrigSndTm=2018-12-02 17:40:39.000, OrigSendingTimeInNano=1543743639000000000, SecurityID=22545, BidPrice=2460.5, BidSize=2, AskPrice=0, AskSize=0, LastPrice=2470, LastSize=8231, msgSeqID=1 [34972:35016:1129/090000:VERBOSE3:iqfeed_md.cpp(34)] OrigSndTm=2018-11-17 17:40:39.000, OrigSendingTimeInNano=1542447639000000000, SecurityID=22551, BidPrice=0, BidSize=0, AskPrice=0, AskSize=0, LastPrice=55000, LastSize=0, msgSeqID=1 [34972:35016:1129/090000:VERBOSE3:iqfeed_md.cpp(34)] OrigSndTm=2018-11-17 17:40:39.000, OrigSendingTimeInNano=1542447639000000000, SecurityID=22551, BidPrice=0, BidSize=0, AskPrice=58000, AskSize=1, LastPrice=55000, LastSize=0, msgSeqID=2
2. Yes indeed, I don't set the protocol when connected.
3. Thanks
There are several questions I met when trying to use your api to receive the quote data from LME. Connection type is Level 1 via TCP/IP, so the questions as the following:
1. As we know, LME opening time is from 1:00AM to 7:00PM, so I ran our application to connect IQFeed Connection Manager at around 00:55AM. Then I received the connection response "S,SERVER CONNECTED" and sent "w[SYMBOL]<CR><LF>" for watching, every thing was ok. But received nothing from the Manager after 1:00AM. However, if I close our application then and run it again, do the same things, the data comes. I don't know why, is there anything wrong, or does it mean I have to connect the Manager after 1:00AM?
2. As Update/Message Summary Format shows, Bid Time/Ask Time/Last Time's resolution is millisecond(eg. HH:MM:SS.ffffff). Actually the the data I got was like "Q,M.ZN3=LX,2505.00,1,2507.00,2,2507.50,956,11/25/2018,22:54:46,22:54:46" (the dynamic fields I select is "S,SELECT UPDATE FIELDS,Bid,Bid Size,Ask,Ask Size,Last,Number of Trades Today," "Last Trade Date,Ask Time,Bid Time\n\r"), the time resolution is just second level. Is that normal?
3. How can I get bid size and ask size from historical data? As Historical via TCP/IP document says, there is only bid price and ask price information in it.
I'm looking forward to hearing from your response.
