PYTHON:Create CRC cards that capture all the features of your trading system and create a class or module diagram. Install a package such as yfinance $($for Python$)$ or yahoo$-$finance $($for JavaScript$),$ pull the

historical data of SOXL and SOXS between $01/01/2021$ and the last market closing date from Yahoo Finance, and save the data in a JSON file on your local machine. A JSON file is structured by key$-$value pairs. The data should include at least the market date, open price, high price, low price, closing price, and volume.

Create a user interface that allows the user to enter a symbol $($SOXL or SOXS$)$ and a date range and display a historical graph. You must use the local data saved in a JSON file to show the graph.

Implement the trading strategy, Simple Moving Average $($SMA$)$ Cross$-$over, and evaluate the performance of the strategy $($backtesting$)$ by calculating $gain or $loss for each trade, the total $ gain or Sloss for all trades, $\%$ return as of today compared to the initial balance. Assume the initial balance is $$100,000.$ Generate a log file in CSV format that records all the trades, including transaction date, symbol, bought$/$sold$,$ price, transaction amount, $gain$/$loss$,$ and current balance. The last row of the file should show a summary including the total $gain$/$loss for all trades, $\%$ return as of today, and current balance.
