Is there an easy way to get the (previous) end of day close price (without having to loop)?

I'm sure you're not talking about something as simple as Close[bar - 1] and the WealthScript Programming Guide > DataSeries > Accessing a Single Value from a DataSeries > How to: Access a value at a specific bar. There must be some catch that you don't tell about like intraday bar scale, right? So to get the previous end of day close price in a one-liner, check this out:

Example:
Assume you have an intraday 5-minute DataSet called "N100_5" and a daily DataSet called "N100" with the same symbols. Here's how you'd get the official close in the intraday chart:
