@run-out I don't think I would call this a small error. If I use a 100 EMA like I'm trying to it's 15.1 on 12/31/2019 compared to 14.35. That's a massive difference and will cause massively different results. If these four values are used to calculate the ema2019-08-08T00:00:00, close: 16.91, ema: nan 2019-08-09T00:00:00, close: 17.97, ema: nan 2019-08-12T00:00:00, close: 21.09, ema: nan 2019-08-13T00:00:00, close: 17.52, ema: 18.37
Shouldn't it be the same from any source as long as the alpha is the same?
