Hi,
I'm trying to pull historical tick data for US equities (using the HTT request) and I noticed that your documentation shows somewhat different results than what I get. I'm using version 5.6.2.0.

My request: HTT,SPY,20171002 083000,20171002 170000,,,,,1,0,1

What I get:
0,2017-10-02 16:01:23,252.2800,535,46479775,252.2800,252.2900,272419,0,0,E,

Your docs (specifically result format section):
http://www.iqfeed.net/dev/api/docs/HistoricalviaTCPIP.cfm

Differences:
* I only get second precision for the time, not microsecond as indicated in the docs.
* The Trade Market Center field is always empty
* There's no Trade Condition number at the end.

How do I get the data in the format specified in the docs? Help appreciated.

Good morning,

The feed defaults to protocol 4.9 for compatibility reasons and I think you are still using that default.
If you just set your protocol to 5.2, for each connection, I think things will match up for you.

This page discusses how to do this.

Thanks. Works fine after I set the protocol.
