Features could include:
- Bid-ask spread
- Bid-ask volume imbalance
- Signed transaction volume
The sign in the Signed transaction volume is positive if the buyer has issued a market order and negative if the seller issued a market order.
A great introductory plain English paper on high frequency trading machine learning applications can be found here.
A good blog post with information relevant to the subject can be found here.

$\begingroup$ That depends on what you are trying to predict. If you are trying to predict an upward movement, then Y could be a binary flag reflecting whether some measure of price increased by a selected amount in the next _ seconds. $\endgroup$– jaamorCommented Jan 19, 2015 at 14:24
