The deconstructed ATR formula I have produced is as follows.
 

 (H-L)*100/(HHV(abs(H-ref(C,-1)) or (L-ref(C,-1)),1))
 

 A horizontal line can be set at 100 and a breakout is viewed as a formula 
result greater than 100. In addition a breakout can also be accepted below 100 
in the circumstances that the formula high for several weeks is broken and that 
previous formula high was below 100.  A breakout is validated when a rally 
occurs on the signal day. Otherwise a rally following the signal day may be 
considered.
 

 As explained the formula is based on one day which I consider superior to 
using the typical multiple day formula. Also the signals are infrequent enough 
to consider the formula useful.
