I would like to use the ATR() function on a 'Foreign' stock - so I can calculate the volatility of - say SPY, but use that ATR value in calculating an indicator on some other security.
For example, there are 2 forms of RSI - RSI(Pers) and RSIa(Array, Pers). Does anyone have a similar ATR function - say ATR(Array, Pers) ? Thanks, ReefBreak
