2 questions:
It appears to me that XAvgLen and ATRLen are reversed above.
Are you guys saying if I use the quick editor: custom 1 line, and type
in xaverage(truerange,20) , that it will not give me the 20 day
exponential average of the true range?
When I should use series vs. simple (or arrays??), when TS is
calculating every bar or not, and when it's carrying a value set on the
previous bar to the current bar, is something that is pretty fuzzy to
me!
