Your daily profit and loss (P&L) is based on your asset balance and the price movements that have occurred since 12:00 AM of the same day.
The detailed formula for calculating valuation profit and loss is as follows.
- Annual profit and loss = Cumulative valuation gain or loss - valuation gain or loss up to the current fiscal year
- Monthly profit and loss = Cumulative valuation gain or loss - valuation gain or loss up to the current month
- Weekly profit and loss = Cumulative valuation gain or loss - valuation gain or loss up to the current week
- Daily profit and loss = Cumulative valuation gain or loss - valuation gain or loss up to the current day
*Profit and loss in price fluctuations of held currencies and open positions are included in the calculation.
*Fees are not included in the calculation.
*Since this is bitFlyer’s own formula, it can not be used for calculating income tax.
