"Thanks for the great product and support. During this week of high volume trading, my QuoteTracker + IQ Feed setup never missed a beat. Also, thanks for your swiftness in responding to data issues.

I am trying to retrieve historical tick data.

But it seems to me the Bid/Ask size are always zero.

Are the ticks only for fills, or do they include L1 changes as well?

Historical data includes trades only. On the historical tick data, we also include the bid and ask price at the time of the trade.
