"Version 4.0.0.2 has been working well for me and I appreciate that it is now a much tighter client to work with. I feel I can go to press with my own application and rely on a stable platform" - Comment from David in IA.
"I just wanted to let you know how fast and easy I found it to integrate IQFeed into our existing Java code using your JNI client. In my experience, such things almost never go so smoothly - great job!" - Comment from Nate
"Thank you so much - awesome feed, awesome service!" - Comment from Greg via Email
"I cannot believe what a difference it makes trading with ProphetX!" - Comment from Bruce in Los Angeles
"I ran your IQFeed DDE vs. my broker vs. a level II window for some slow-moving options. I would see the level II quote change, then your feed update instantaneously. My broker's DDE, however, would take as much as 30 seconds to update. I am not chasing milliseconds, but half a minute is unacceptable." - Comment from Rob
"I started a trial a few weeks back before the market went wild. DTN.IQ didn’t miss anything and beat my other provider. I decided to stay with you because of the great service through all the volatility." - Comment from Mike
"I just wanted to tell you what a fine job you have been doing. While *******, from what I hear, has been down and out, off and on, IQ feed has held like a champ this week." - Comment from Shirin
"I have been using IQFeed now for a few years in MultiCharts and I have zero complaints. Very, very rare to have any data hiccups or anything at all go wrong." - Comment from Public Forum
"I have to tell you though that using the IQFeed API is about the easiest and cleanest I have seen for some time." - Comment from Jim
"Interactive Brokers tick data was inconsistent, so I have switched to using DTN exclusively. It is great to no longer have to worry about my datafeed all day long." - Comment from Philippe

IQFeed Developer Support » Not getting historical Tick data Apr 3, 2018 12:29 PM (Total replies: 2)

Hi I am new to IQfeed and DTN. I am using the Developer license. I am generally interested getting historical data for testing purposes. I am using Python on Windows 8.1. I found a small script on the forum that I adapted to download 1 min data and it works just fine. I have just downloaded a stocks in the S&P500. However I am struggling with tick data downloads. I have tried HTT and HTX but no joy at all.

I have failed to get anything from the example scripts as well.

The edited script that I am using is below. I would appreciate any guidance on this as well as anything relate to python that I need or I may be missing. For Python 2.7 I am using Anaconda (64 bit)

*************************************************************************

import sys
import socket
import string

startdate= '20180101 093000'
enddate = '20180326 160000'

def readHisSock(sock, recv_buffer = 4096):
buffer = ""
data = ""
while 1:
data = sock.recv(recv_buffer)
buffer += data
if "!ENDMSG!" in buffer: break
return buffer[:-12] #removes endmsg line

host = "127.0.0.1" #localhost
syms = ['GE', 'AAPL']
dir = "C:\Users\My Documents\LiClipse Workspace\IQfeed_data_download"

port = 9100 #history socket

for sym in syms:
f = open(sym + ".csv", "w")
message = "HTT," + sym + "20180101 093000, 20180326 160000,,093000,160000,,,,1\n"
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((host, port))
s.sendall(message)
d = readHisSock(s) #d is a string
s.close

d = "".join(d.split("\r")) #server sends multiple endlines
d = d.replace(",\n","\n")[:-1] #server has comma delimiter at end of each record

f.write(d)
f.close()
