Hi All. Was messing around in a notebook trying to learn more of the mathematics of trading today. Was calculating a 14-RSI for Tesla (TSLA), but my end calculation for yesterday was 57.423881 while around 78.7 was what was being reported. Did it again by hand and still came out with the same answer.
I referenced this for the calculation: http://cns.bu.edu/~gsc/CN710/fincast/Technical%20_indicators/Relative%20Strength%20Index%20(RSI).htm
Thanks in advance for any feedback!
