Light start on the calendar is the iPeople await word.

We've been warning that the US dollar is super-sensitive to economic data but today's meal of scheduled economic news is still probably to thin to move the needle.

The best bet is at 9:45 am ET (1345 GMT) when the Markit US services PMI is released. It's expected to slip to 58.8 from 59.2 and is a preview for the ISM non-manufacturing data due next week.

At 10:30 am ET ( 1430 GMT) it's the Dallas Fed manufacturing report, which is expected to rebound to -12.0 from -17.4 (worst since mid-2013). Only a handful of economists bother to forecast it.

Frech jobseeker numbers are due at noon ET (1600 GMT) with those looking for work expected to hit 3500K from 3494K.4K. An hour later it's a 2-year Treasury auction.

The main event for the stock market bulls comes after the bell when Apple releases earnings. With the Nasdaq already at all-time highs, stocks will go into overdrive on a beat.
