Trading With Tick Index: A Comparison of DTN IQFeed and eSignal NYSE Tick Index
This article explains how to translate the interpretation of NYSE Tick Index between the eSignal version and the IQFeed version.
Frame of Reference
I use the eSignal version of NYSE Tick Index extensively for backtesting and signal generation. It is not that it is better than the other ones. It is a habit now as I have monitored the same index for 20 years. I use the eSginal version of NYSE Tick Index to write this series of articles too.
The advantage of the eSignal version is that I have access to all the historical data of the index going all the way back to the 1990s. It enables me to understand the changes happening to the index and how it evolved over time.
Currently eSignal NYSE Tick Index (symbol $TICK) is updated every second, just like the one offered by DTN IQFeed (symbol JTNT.Z). Both of them are updated during US session stock market hours from 9:30 am to 4:00 pm Eastern Time. From these second by second real-time update we can construct minute bar, etc. easily to line up with the other data for comparison.
