I saw that there's a markdown-live-preview-mode and the var markdown-live-preview-window-function which was set to the function markdown-live-preview-window-eww. That function looks like this:

(defun markdown-live-preview-window-eww (file)
  "Preview FILE with eww.
To be used with `markdown-live-preview-window-function'."

def RSI(series, period=14):
    delta = series.diff().dropna()
    ups = delta * 0
    downs = ups.copy()
    ups[delta > 0] = delta[delta > 0]
