Numerical Examples of Everlasting Option Pricing

We have proved the following pricing formulae for everlasting options under the BSM assumptions.

Let’s divide the theoretical prices of everlasting call and put options, Cᵉᵛᵉʳ and Pᵉᵛᵉʳ, into intrinsic value and time value:

The call and put options at the same strike have the same time value

The details of the math can be found in this article. Here we provide some numerical examples. Let’s take the BTCUSD-50000-CALL with 7Day funding period as an example and assume volatility = 100%:

Then we have the key intermediate variable

Assuming BTCUSD = 40000, then we have intrinsic value I = 0, and time value

Therefore, the theoretical price of this 50000-Call is

Every day, a long (short) position of 1BTC of this EO pays (receives)

Assuming BTCUSD = 50000, then we have intrinsic value I = 0, and time value

Therefore, the theoretical price of this 50000-Call is

Every day, a long (short) position of 1BTC of this EO pays (receives)

Assuming BTCUSD = 60000, then we have intrinsic value I = 60000–50000=10000, and time value

Therefore, the theoretical price of this 50000-Call is

Every day, a long (short) position of 1BTC of this EO pays (receives)
