In this blog, I will make ASX200 stocks market dashboard with the moving average convergence divergence (MACD) indicator in the tableau. The MACD indicator is a common tool used by traders to identify the stock momentum.
Yahoo! Finance https://au.finance.yahoo.com/australia/ is an excellent website that provides financial news, stock quotes, press releases, and financial reports. In this case study, I use the yfinance library in python to download the ASX200 stock daily historical data for the past five years.
A MACD chart includes three parts. The first part is the difference between the 12-day and 26-day exponential moving average (EMA) of the closing price; this is the MACD line. The second part is the EMA of the difference, which is known as the signal line. The third part is call histogram which is the MCAD minus the signal
- MACD Line: (12-day EMA – 26-day EMA)
- Signal Line: 9-day EMA of MACD Line
- MACD Histogram: MACD Line – Signal Line
Part1 MACD Line: (12-day EMA – 26-day EMA)
(1) 12-day EMA：
Part2 Signal Line: 9-day EMA of MACD Line
Part 3 MACD Histogram: MACD Line – Signal Line
After making all the above calculations, drag MACD Line and Signal Line into the canvas as line chart and pull MACD Histogram as Bar chart
The ASX200 Stock Market Dashboard
I divide the stock market dashboard into two pages; The first page is the overview of the daily performance of the ASX200 index and a Treemap visualization of the stock where boxes size indicate companies’ market capital, a color incident the daily Up/Down trend. Users can also filter the date and sector to focus on a specific group of stocks in the Treemap. When the user clicks the stock in Treemap and tooltips pop up, which can direct the user to the MACD analysis page for further analysis.
