One more thing...

I am guessing when I trade BTC for XRP, you are using 2 seperate pricing databases to get the purchase and sale price, correct?

You are grabbing the BTC price and the XRP price seperately, right?

This is causing big errors when recording trades because your databases aren't that accurate.  

I have a suggestion, lets say I am trading BTC for XRP.  Why not just use the BTC price(I assume this database is your most accurate), and then subtract the trading fee to come up with the Altcoin price?  This would be much more accurate.  Currently when I am switching from best, transaction, and counterparty pricing, I am seeing huge(2x) differences in my realized gains numbers which is not giving me much confidence in the software.
