Summary: Generate a correlation heatmap based on historical price comparison between similar companies. You can choose the type of candle data to use (open, high, low, close, adjusted close, or returns), specify a date range, display the full matrix, and export the data in various formats.

Examples:
- To generate a heatmap using adjusted close prices: stocks/ca/hcorr -t a
- To generate a heatmap using high prices between specific dates: stocks/ca/hcorr -t h -s 2022-01-01 -e 2022-12-31
- To display the full correlation matrix: stocks/ca/hcorr --display-full-matrix
- To export the heatmap data in CSV format: stocks/ca/hcorr --export csv
- To save the heatmap data to a specific Excel sheet: stocks/ca/hcorr --sheet-name Sheet1
- To display raw data of the heatmap: stocks/ca/hcorr --raw
- To generate a heatmap using returns for a specific stock: stocks/load <SYMBOL>/ca/hcorr -t r
- To generate a heatmap using low prices for a specific stock between specific dates: stocks/load <SYMBOL>/ca/hcorr -t l -s 2022-01-01 -e 2022-12-31
