Comments: 

Note that this differs from the "DailyHigh" in that the High is always related to an interval (1 minute bar, 15 minute bar, daily bar, etc.) and is always relative to a point in time (current bar, previous bar, bar-5, etc.) 

Examples:

High(5)

The high for the current symbol for the last 5 minute bar.

High(60, 0)

The high for the current symbol for the last 60 minute bar.

High(5, -1, YHOO)

The high for the YHOO for the previous 5 minute bar.
