Tiger Brokers Hong Kong

Tiger Trade supports both long and short positions in US options trading.

Due to exchange regulations, pre-market and after-hours trading is not available for US options. However, orders can still be placed outside of trading hours, and Tiger Trade will execute the orders when the market opens.

Yes, relevant features have gone live.

The value of your options position will remain unchanged after a stock split, but the contract price and quantity will change according to the split ratio. Existing options will be traded under a new symbol, and liquidity may be reduced.

Majority of US stocks and ETFs are eligible for options trading.

Navigate to your portfolio, click 'Close' to close your combination order. In an event where users try to close a leg of an option that belongs to a specific combination, Tiger Trade will issue a reminder to avoid unintentional alteration in margin requirements.

Margin discounts are currently available for ：

• Covered Call: Investors hold underlying assets, typically stocks, and sell an equal number of call options.


• Covered Put: Investors maintain short positions and sell matching put options.


• Put Vertical Spread: Buy a put option at a higher strike and sell one at a lower strike.


• Call Vertical Spread: Buy a call option at a lower strike and sell one at a higher strike.


• Short Call and Put: Sell both a call and a put option.


• Protective Put: Combine stock ownership (or current holdings) with buying matching put options.


• Protective Call: Involves buying call options while holding equivalent short positions.


• Put Calendar Spread: Trade two put options with different expiration dates but the same strike price and underlying asset.


• Call Calendar Spread: Trade two call options with different expiration dates but the same strike price and underlying asset.

Combining new holdings with existing positions into an option strategy can lower margin requirements.

Partially closing your option strategy invalidates the order, ending margin discounts and raising risk. If Excess Liquidity (EL) drops below zero, it could force liquidation. Ensure your account is well-funded before closing any part of an option strategy.

To avoid margin increases when closing, settle the options in the strategy before the underlying stocks. Closing stocks first can invalidate the option strategy, increasing the margin due to separate requirements for remaining positions.

The fee structure for multi-leg options is consistent with that of single-leg orders, where each leg is billed as an individual contract (specific rates can be found on the official website). The total cost of the combination is calculated by aggregating the fees for all contracts involved.
