Leere Plotly Candlestick -Chart mit yfinance.download () ⇐ Python

[Guest]

Ich versuche, ein einfaches Candlestick -Diagramm aus OHLCV -Daten zu zeichnen, die von YFInance abgerufen wurden. < /p>
Dies ist mein Code: < /p>
import yfinance as yf
import pandas as pd
import plotly.graph_objects as go
from datetime import datetime

tf = '1d' # Time frame (daily)
asset = 'AAPL' # Asset ticker (e.g., Apple)
start = '2019-01-01' # Start date
end = datetime.now().strftime('%Y-%m-%d') # End date is current date

df = yf.download(asset, start=start, end=end, interval=tf)

df['pct_chg'] = df['Close'].pct_change() * 100

df.index.name = 'timestamp'

# now plot the chart

hover_text = [f"Open: {open}
Close: {close}
Pct: {pct_chg:.2f}%" for open, close, pct_chg in zip(df['Open'], df['Close'], df['pct_chg'])]

# Create a candlestick chart using Plotly
fig = go.Figure(data=[go.Candlestick(
x=df.index,
open=df['Open'],
high=df['High'],
low=df['Low'],
close=df['Close'],
hovertext=hover_text,
hoverinfo='text'
)])

# Update layout
fig.update_layout(
title='Candlestick chart',
xaxis_title='Date',
yaxis_title='Price',
xaxis_rangeslider_visible=False,
template='plotly_dark')

# Show the plot
fig.show()
< /code>
Daten werden korrekt heruntergeladen. Die Grafik zeigt jedoch keine Kerze an.
