IExposure to Excel Add-on

There is one excel file. Within this file there are sheets where data from one broker are shown in one sheet, another broker in another sheet.

The goal is to get the totals of “Buy Lots”, “Sell Lots”, and “Profits” of all open pairs, from all sheets into one main "TOTALS" sheet. This "TOTALS" sheet is within the same Excel file.

“Buy Lots”, “Sell Lots”, and "Profits" columns in "TOTALS" sheet sum all respective pairs  - see my attachments.

With Regards.
