In the meantime, there is an easy workaround for this (which it looks like you have attempted, but you may need to add secondary_y=False to get it to look right).

If df is your dataframe containing OHLCV data, then

df['rsi_overbought'] = [80.]*len(df)
df['rsi_oversold']   = [20.]*len(df)
ap = mpf.make_addplot(df[ ['rsi_overbought','rsi_sold'] ], secondary_y=False)
mpf.plot(df,...,addplot=ap)

HTH. Thanks. --Daniel
