[EquisMetaStock Group] Why Metastock return a wrong ATR(10)?

[chichungchoi <no_reply@xxxxxxxxxxxxxxx>]

Does anyone know why Metastock cannot return an accurate ATR(10) value?

[10 TRUE RANGES]
424.4297
180.4785
149.3496
544.2793
267.6289
228.3398
221.6406
204.0898
241.6602
241.7188

[Calculating ATR(10)]
ATR(10) provided by Metastock is 250.631
ATR(10) provided by Excel is Sum(10 data)/10 = 270.361
Both results are different, do I use the wrong approach to calculate ATR
(10) by Excel? or do Metastock return a wrong ATR(10)?
Does anyone have any suggestions?
Thank for any suggestions
Eric
