On Day 1, you purchase 2 ETH at a price of 3000, and the last price is 3500. Average cost price Average cost price = (0 + 3000 * 2) / 2 = 3000 PnL = (3500-3000)*2 = 1000 PnL Ratio = (3500 - 3000)/3000 * 100% = 16.67% Cumulative Cost Price Cumulative Cost Price = (3000 * 2 - 0)/2 = 3000 PnL = 3500 * 2 - 3000 * 2 + 0 = 1000 PnL Ratio = 1000 / (3000 * 2 - 0) * 100% = 16.67% Scenario 2: On Day 2, you sell 1 ETH at a price of 3500, and the last price is now 4000.
