Pick - Function Summary
Returns the value at the specified position in a series.
pick series index
series - The series argument. (must be: series pair event money date time object port tuple any-function)
index - The index argument. (must be: number logic pair)
The value is picked relative to the current position in the series (not necessarily the head of the series). The VALUE argument may be INTEGER or LOGIC. A positive integer positions forward, a negative positions backward. If the INTEGER is out of range, NONE is returned. If the value is LOGIC, then TRUE refers to the first position and FALSE to the second (same order as EITHER). An attempt to pick a value beyond the limits of the series will return NONE.
