I am testing "matplotlib.animation" using the stock market index (NASDAQ in this case example) and the stock market price (Amazon in this case example)
# Parameter Adjustment
# Set Ticker Symbol
# e.g. Ticker="^GSPC" for S&P 500, Ticker="NDAQ" for NASDAQ, Ticker="TOPX" for TOPIX
Ticker_index="NDAQ" # Ticker sympol for the index
# Ticker="AMZN" for Amazon, Ticker="NTDOY" for NINTENDO
Ticker_stock="AMZN" # Ticker symbok for a stock
# Set the number of years to download data
No_Years_Data=1;
# Set the numbers of days for the future forecast
No_Days_FutureForecast=250*1
