Thanks for the feedback Quon, I guess I'm not being clear. This may be in part because I've modified Fisher's method. I use the ATR of the OR for each time frame I'm looking at. Rather than use 20 - 25% of the daily ATR for the daily A I use a multiplyer on the OR ATR. The methods are generally fairly close to one another, but by using the OR ATR my A values are much more sensitive to changes in volatility and experience shows they are quite accurate.
