I don't know whether Bourse software includes the Coppock indicator. You will need to ask the vendor.
If you find that it is not included, here are some options:
1. Bourse software may allow you to write your own indicator formulas. If so, you can use my articles and the spreadsheet on my web site to try to write a formula. See also the formula for MetaStock in Newsletter No 30, which may use a similar method for writing formulas. Make sure that you check your results against my spreadsheet.
2. You could just rely on the spreadsheets on my web site. The Coppock indicator is calculated only once a month at the end of the month. I update the spreadsheets at the end of each month.
3. You could import the spreadsheet Coppock numbers into a data file to chart as a line chart in Bourse. Then use the spreadsheet to calculate the new value each month and enter it by hand into the data file.
