For each date, evaluates a formula for each symbol,then calculates the percent rank of each symbol's value among all symbols on that date and stores those percent rank values in the data item array.
Syntax
#PercentRankformula
Notes
The largest value will have a percent rank of 100, the lowest value 0, and the others will be distributed evenly between those extremes.
Example
PriceRankToday: #PercentRank Close
Notes
If the formula result is nan (not a number -- unable to calculate)then that stock is not included in the ranking list (reducing the total count) and its rank value would be nan as well.
