NEW YORK, April 29 (Reuters) - Wall Street was set for a higher open on Tuesday following a batch of earnings that were better than expected.

* Twitter is due to report after the market closes Tuesday.
* Archer Daniels Midland Co shares fell 2 percent in premarket trading after its first-quarter profit and sales missed Wall Street estimates.
