The amount received (after tax), the actual amount of tokens purchased (optional) the rate, and the total cost paid in USD for a particular token in a given wallet. Say I am buying WNOW when it dips. I would to know how much I bought, how many times and dates, the cost of that purchase. Same thing goes for selling as well. A total at the bottom of the chart can show the totals and the compare the current market price against the cost I paid and sold for. So it would give me an accurate P/L number.
