Hello.

I have developed an Excel worksheet to track my surebets. I have posted a topic about it (

http://arbusers.com/index.php/topic,973.0.html)

I am planning to sell this Excel if someone finds it usefull. I have a trial version.

The main purpose of the excel is to track bets and analyze performance.

However, the Excel includes a simple calculator both to back vs back and back vs lay.

Both calculators manage commissions.

You can set a global stake and the calculator will tell you how much to back and lay (taking into account the odds and commissions).

It does not calculate automaticaly how much to lay if you enter the backed amount, but I can work on it. It could be a good improvement

Anyway, it is very easy to play with the total stake and try different values until you get the amount you backed (and also the amount to lay)

If you would like to test it, the trial version of my Excel has the calculator available without restrictions.

PM if you want me to send the Excel.

PS: it needs Windows and Excel 2007 or later.

Regards,
