Long time ago I alerted errors in EMA display and calculation and was contributory to the improvement thereof.
It seems another indicator is in error... if one opts for a non default ATR"n" value...
I tried to download an example - your software flagged file too big - 2 Meg is maximum...
so I truncated the file to 1M7... - your software flagged file too big - 256k is maximum...
so I gave up - I shall just calculate my OWN indicators.
