Quote from Wayne Gibbous:
You should log every trade in Excel. Yep, every single one. Even if there are thousands.
This log should include date, basis, method, security, P&L, commish, notes, etc. With that data you can create any chart or stats you want.

Here's an example of how you can keep track of the aggregagate totals. You'll have to customize the spreadsheet to your specific situation for best results.

Thanks, but why ending and beginning balance. Isn't one enough? My ending balance is always the same as my beginning for the next month.
