So let us start with Put-Call Parity.
I. Put-Call Parity
Compared to the BS model, especially which requires dynamic hedging, Put-Call Parity has been recognized as static replication(hedging), which entails less transaction, theoretically.
C - P = S - K ∙ D
II. How this principle can be used as a trading strategy?
P — C + S — K ∙ D = 0
For example, assuming that the current spot price of BTC is traded at 8,000, and discounted strike price with respect to time and the risk-free rate is 7,850. And, found in the market that call option price is 1,160 and Put is 1,010 for same strike, same expiry option. Thus, 8,000–1,160 + 1,010–7,850 = 0, shows put-call parity is working. AND if those not equal to zero, then there is a chance for trading. However, please be aware that those option prices are based on BTC, so will be on the market as 0.1450 (:= 1,160/8,000), 0.1263 (:= 1,010/8,000), respectively.
Furthermore, even OKEx BTC option is not designed as an option on futures, however, as futures price is based on the same index, same time horizon to daily settlement, maturity, market’s risk-free rate, etc, it’s worthwhile to cross-check our futures and perpetual swap market as proxy and possible opportunity. As market matures, those relationship will be strengthened. In that case, the alternative Put-Call Parity formula, which may help your easier calculation, is given below.
P — C + D ∙ (F — K) = 0
At the start of simulation trading period, we have seen pretty odd, jumpy, unstable prices and volatilities. However, at the end of the term, we observed better shape of volatility surfaces and price connection to the existing markets. At the time of live trading, we are expected to see this, but will find the right and healthy figure soon. Thus, as indicated via this article and targeting ourselves as one-stop cryptocurrency exchange, OKEx BTC option would contribute the price discovery and transparency, well-managed volatility of whole crypto markets, leading to the integrated global financial system.
