About this page
This page is one route: the prices of two exchanges, the spread before and after fees, the profit by the order books, the coin transfer status, a verdict and the spread's history. Below are the live chart for 6 hours, 24 hours, 7 and 30 days, both exchanges' order books and the trade step by step. A spread after fees is not the profit: the books' depth, the withdrawal fee and the time the coins are in transit all count.
