DTN.IQ Client Software Support » How to check if Level 1 symbol is invalid? Jul 13, 2014 08:54 PM (Total replies: 3)

Thanks a lot, I'm using IQFeed 5.1 protocol. And I can see the n,QPPG now.

This solved my problem.

DTN.IQ Client Software Support » How to check if Level 1 symbol is invalid? Jul 11, 2014 04:33 AM (Total replies: 3)

My question is same as topic name:

How to check if Level 1 symbol is invalid?

I send wAAAA.TES\r\n as a watch command for example, but I don't receive anything from level 1 port. My expectation is some kind of messages like "Invalid Symbol" or I should check if AAAA.TES is valid before sending.

By the way, what is different between watch(w) and trade(t) command?
wMSFT and tMSFT...
