File Name: SymbolCompareAsNPS2.efs

Description:
Compare a symbol to your chart symbol as a non-price study with H/L bars.

Formula Parameters:
Symbol: Any valid symbol (Spread symbols are not valid for this formula).
Number of Bars: Default is 200. Max/Min Limits: 200/1
Bar Thickness: Default is 2. Controls the thickness of the H/L bars.
Up Bar Color: Default is green.
Neutral Bar Color: Default is grey.
Down Bar Color: Default is red.


Notes:
After applying the formula, go to "Edit Studies" and enter a symbol. The formula also draws the high/Low bars and the open, similar to a bar chart.
