In traditional options trading, delta and gamma, as known as BS delta and BS gamma, are derived from the Black-Scholes or Black options pricing model. BS delta measures the rate of change of the option price relative to the change of underlying price. BS gamma measures the rate of change of BS delta relative to the change of underlying price. For the OKX BTCUSD options contract, the calculation of delta and gamma is different from the traditional way.

Discount based on BS Delta: a separate discount coefficient between 0 and 1 is applied to value of each OTM option. The smaller the absolute value of an option's BS Delta, the smaller the coefficient value is. The coefficient is set to 0 for deep OTM options, i.e. deep OTM options can not be used as collateral for borrowing at all. Upper limit: in each PM account, the sum of values of all long options after adjustments a & b above is further capped at a pre-defined upper limit level.

If you carry out multiple trading strategies, including spot trading, bot trading, options trading, or other non-lead contract trading, data from these trades will be removed from your PnL calculation and your lead trade data and PnL curve will change.

However, this approach resulted in the inclusion of data from non-lead contract trading, spot trading, bot trading, and option trading in the PnL calculations, making it difficult to specifically measure lead trade data.
