I haven't looked at athena but I do recommend having a look at Stator which has a free download. It is portfolio management software that has a very good position sizing calculator included amongst a lot of additional features. The author is continuously developing the software. It is a great product.

PS I have no financial interest in Stator. Just a very happy user.
Thanx for that Shane
