There is no law that says you have to record every transaction. On your tax form, there is a field where you put in the total amount gained or lost over the entire year. For 2014 I lost money, so in my tax form, I didn't put anything. For 2015 I will probably break even across all buys/sells. Maybe for 2016 the price will rise and I'll end up making a net profit after adding up buy and sell spreads. You don't have to be exact, you just have to give it a goo guess. If you guess too large, you pay more in taxes, if you guess too low, you pay less in taxes, but run the risk of getting in trouble if audited. I guess if you wanted to get brownie points with your accountant, you can record all transactions, but if you don't you certainly aren't breaking any laws.
