import pybithumb
import numpy as np
import pandas as pd

df = pybithumb.get_ohlcv("BTC")
df = df['2018']

df['range'] = (df['high']-df['low']) * 0.5
df['target'] = df['open'] + df['range'].shift(1)

df['ror'] = np.where(df['high']> df['target'], df['close'] / df['target'], 1)
df.to_excel("btc.xlsx")

ror = df['ror'].cumprod()[0]
print(ror)
