US multi-leg options order may consist of either a combination of US options or combination of US options + stocks/ETFs. Each leg in a multi-leg options order is charged separately and subject to the minimum fee rate. Total fees are calculated by adding up the fees for each individual leg.
Example 1:
To build a long covered call, an investor buys 100 shares of the underlying stock at US$35 per share and simultaneously sells 1 call option on the same underlying stock at US$5. The commissions and other transaction fees for the 100 shares of stock and the 1 option contract are calculated separately, all subject to their respective minimum fee rates.
Taking the commission as an example, the commission for 100 shares of stock is 100 * US$0.0049 = US$0.49, while the minimum commission per stock order is US$0.99, and thus the commission for the 100 shares of stock is US$0.99. The commission for 1 option contract is 1 * US$0.65 = US$0.65, while the minimum commission per option order is US$1.99, and thus the commission for the 1 option contract is US$1.99.
Therefore, the total commissions are US$0.99+US$1.99 = US$2.98.
Example 2:
To build a long straddle, an investor buys 1 call option and 1 put option on the same underlying stock at US$6.5 each, both with the same strike price and the same expiration date. The commissions and other transaction fees for the two-leg option contracts are calculated separately, all subject to their respective minimum fee rates.
Taking the commission as an example, the commission for 1 call option contract is 1 * US$0.65 = US$0.65, while the minimum commission per option order is US$1.99, and thus the commission for the 1 call option contract is US$1.99. The commission for 1 put option contract is 1 * US$0.65 = US$0.65, while the minimum commission per option order is US$1.99, and thus the commission for the 1 put option contract is also US$1.99.
Therefore, the total commissions are US$1.99 + US$1.99 = US$3.98.
