IQFeed data NOT so true tick or is it? Iâm just wondering if anyone has ever compared the data feed from IQFeed to another True tick data providers. I have done a comparison using the Time and Sales from IQFeed (Sierra Charts) and the Zen Fire (Ninja), (also did one before using Transact data and similar result was found). Clearly from what Iâve found was that, IQFeed consolidated some of the traded contracts. (Examples are highlighted in the attached image - #ESH8). Question - is it because IQFeed record a tick as an initiating trade? For example, Trader-A buys at market 10 contracts, which is filled from the other side by 2 offers of 5 contracts each. In this example, a Tick recorded by IQFeed would be one tick of 10 Contracts. In a reverse logic (example of Zen Fire), it would be recorded as 2 separate trades of 5 contracts each. Which is correct? If IQFeed isnât really providing a True Tick data then they are ripping their customers off (including ME!!)? Thoughts?
