What's the difference between real-time and bulk valuations?

The electronic messages can take many different formats, but are usually supplied as:

Individual real-time – a direct request to the provider who responds with the latest valuation.

Bulk valuations – a file containing the valuation at a point in time, most are supplied daily but could be less frequently such as weekly.

The information supplied can vary, but would normally contain a current valuation, date and time, valuation details supplied along with the funds and units held.
