Startup Idea: Crypto-Fiat Trading Journal and Tracker

Startup idea to develop a software that could track and visualize the crypto-fiat trading progress of an individual across multiple exchanges. The tracker should provide API and XML support, enabling users to oversee their buying, selling, and capital gain activities for better investment decisions and taxation purposes.

In my spare time I trade fiat and crypto-currency assets.

A big pain that I find I am consistently dealing with is keeping a trading journal of all of my combined trades across exchanges to see my progress and track my results over the year. I have to collect the data myself even though many of these sites offer an API.

If there was some sort of tracker that also had visual data and XML support that could create a visual representation of all of my trades across exchanges that provide an API, I would definitely pay for it. Coinigy is the only real competitor offering any sort of cryptocurrency trade tracking ad it still doesn't provide anything like this.

This would also be incredibly useful to see total bought, sold, and total capital gains in one look to use for taxation purposes. Yes, coinigy is the closes thing I have found, it connects to different exchanges and lets you check your individual trade history but no sort of graphic or complete combined trade record.
