Software or tools for tracking your Bitcoin trades?

[forbun]

I would like to use some kind of tool for keeping track of my trades. I would like to know, based on the USD I've spent, and the BTC I've gotten for it, what my average USD/BTC is. I would like this number to take into account commissions, factoring them into the price of BTC (or vice-versa).

I don't currently use any tool because I don't know of any. What's out there? What can beginners use? What do professional traders use?

Which tools are out there?

I'm currently in the process of working on a tool that will be able to track profit & loss on open/closed trade positions as one of its features. 

I'm hoping to have the first iteration out by the beginning of October which will mainly just be charting and streaming quotes, with the next version containing functionality for placing and tracking trades.
