Using MPD Efficiently (Mixed Periodicity Data Indicator)

Anyone using MPD in any context should watch this video. This video demonstrates how to make the most efficient use of the MPD (Mixed Periodicity Data) indicator, which can be extremely inefficient without the use of the special method.

I've worked with a number of users over the past few weeks that seem to be running into a common problem. Essentially, the problem manifests itself as periodic pauses or "freezes" in the program, or the data begins lagging behind. The source of the problem in some of these cases has been inefficient use of the MPD indicator. This indicator by default loads the data of it's underlying periodicity each time it calculates. This loading of data form the database can be very slow and can be the source of the pauses or lags. By adding the underlying periodicity directly to the chart (invisibly) as demonstrated in the video, the MPD becomes very efficient and calculates instantly.

I've also posted some related videos below the video. I would recommend watching them all if you haven't already.
