Are there any issues with History servers?

IQFeed Developer Support » HTT Usage May 15, 2009 02:27 PM (Total replies: 1)

Whats the best way to use HTT command to get ticks for say 10 stocks every 5 mintues?
How should the begintime and endtime be used effectively?

It seems New Server that has seconds support does not return valid tick history data and only returns atmost for 1 previous day. I tried with AAPL and it works but does not work for GOOG.

IQFeed Developer Support » Multiple Connections to port 9100 Dec 5, 2006 06:30 PM (Total replies: 6)

I am watching total of 250 L1 symbols, distributed across 4 L1 ports.
Also I am watching same 250 symbols on L2 again distributed across 4 L2 ports.

My application is able to process all data for a while but then it seems to loose connection to IQConnect.

IQFeed Developer Support » Multiple Connections to port 9100 Dec 5, 2006 09:07 AM (Total replies: 6)

Updating above post ... I connect to 5009 (for multiple L1) and 9200 (for multiple L2).

IQFeed Developer Support » Multiple Connections to port 9100 Dec 5, 2006 08:55 AM (Total replies: 6)

Is there any known issue with multiple connections to port 5900. I currently have 4 connections to L1 port and 4 connections to L2. When I start watch on 250 symbols, initially I am able to retrieve data from IQFeed but after some random time, I am not able to retrieve data. I can see that IQFeed is still retrieving data and CPU goes to 100% but either my application is not pulling data or IQFeed is not publishing it. Do you think multiple connections might cause this issue?

Is there near future plan for providing Nasdaq TotalView feed? If not, do you recommend other sources that are compatible with IQFeed for retrieving TotalView data.

Would appreciate your response.

IQFeed Developer Support » Level 2 'U' Message Documentation Clarification Jul 17, 2006 02:03 PM (Total replies: 11)

Is Level 2 'U' Message documented response not matching with what is returned from servers. I see
================== As Documented =================
A Level II Update, a comma separated line of text indicating the values for the update. The message is defined below.
symbol - [out] The Security's Stock Symbol
mmid - [out] The ID of the Market maker originating the quote update
ask - [out] The Buy Offer Price
ask_size - [out] The size of the Buy Offer
bid - [out] The Sell Offer Price
bid_size - [out] The size of the Sell Offer
date - [out] The date and time the update occurred
reason - [out] The reason code for the update
condition_code - [out] The condition of the update
source_id - [out] The quote source's id

As received from servers.

As seen, date field is also separate fields. Please clarify how to interpret L2 data.
