Candle stick colors incorrectly colored

[lcobiac]

Hi Daniel,

Im running the following code and getting incorrect colors for the cande sticks. Output and screenshot are given below. Please advise.

Code

import mplfinance as mpf
import pandas as pd
print("mpf version:", mpf.__version__)

AAL_csv = pd.read_csv('./data/F.csv', index_col='timestamp', parse_dates=True)
print(AAL_csv.head())
mpf.plot(AAL_csv[['open', 'high', 'low', 'close']][-20:], type='candlestick', style='yahoo')
plt.show()

Output

mpf version: 0.12.7a0
            open  high    low  close    volume
timestamp

I notice this is also the case in the screenshot in #247

I have realized there are no issues with the colors. My data is in reverse order when compared with the expected input.

Thanks. I should probably put a check in the code and issue a warning if the datetime index appears to be going in the wrong direction.

Or automatically reverse the order of the data.
