Candlestick Chart using Python

A candlestick chart is a data visualization tool used to analyze the price movements of stocks, cryptocurrencies, currencies, and other financial instruments. If you work as a data scientist/analyst in the finance domain, a candlestick chart is one of the most important data visualizations for you. So if you want to learn how to visualize a candlestick chart, this article is for you. In this article, I will walk you through how to visualize a candlestick chart using Python.

Candlestick Chart using Python

To visualize a candlestick chart using the Python programming language, you can use any data visualization library in Python like Matplotlib or Plotly. The plotly library provides better features for visualizing a candlestick chart and also makes it interactive at the same time. So in this article, I will be using the plotly library for visualizing a candlestick chart.

As this chart is mainly used to analyze the price movements of financial instruments, so I will be using the Apple stock price data for this task. I have collected data on Apple’s stock price for the past three months from Yahoo Finance. You can either collect a dataset from Yahoo Finance or download the same dataset I’m using for this task from here.

So below is how we can visualize a candlestick chart using Python:

import pandas as pd
data = pd.read_csv("AAPL.csv")
import plotly.graph_objects as go
figure = go.Figure(data=[go.Candlestick(x=data["Date"],
                                        open=data["Open"], 
                                        high=data["High"],
                                        low=data["Low"], 
                                        close=data["Close"])])
figure.update_layout(title = "Apple Stock Price Analysis", 
                     xaxis_rangeslider_visible=False)
figure.show()

If you don’t know anything about the candlesticks in this chart and how you can analyze a candlestick chart as a data scientist, you can learn all about it here.

Summary

So this is how you can use the plotly library in Python for visualizing a candlestick chart.
