OK, I finally completed my spreadsheet and I took the time to verify the calculations by hand so I know this should be the final version that works very well. If you want to use the file with the original program I used to write it, itâs free at...(you click on Calc after installation) http://www.openoffice.org/ And some tips on how to use Microsoft Excel (the spreadsheet in the free Open Office is supposedly a âcloneâ of Excel)... http://www.youtube.com/watch?v=8L1OVkw2ZQ8 This spreadsheet will calculate the total profits or losses (including commissions as well), your percentage of winning trades (and losers), average profit or loss per trade, average percentage profit on winners (and losers as well), risk/reward ratio, number of winners (and losers) and total profits and total losses. All you have to do is type in your ticker symbols, entry price, exit price, number of shares traded, whether it was a long or short position and the commissions column you donât need to fill. (You can always click to change the formula and insert the right amount instead of $25. So, tell me if you like it.
