Thanks everyone for their reviews.

Would you like me to more actively develop the upcoming trading application or the spreadsheet?

It may be more useful to put my time into the actual application, since the spreadsheet is limited to excel 2010/2013, while the application is for all platforms.

Let's hear some more feedback before I make some decisions.

Live arbitraging will be added anyway, either in the spreadsheet or in the application.

More screenshots will follow soon.

Price is still 0.075 BTC.
