Both long and short positions in US options trading.

US options trading is not available outside regular market hours. However, orders can still be placed outside of their trading hours, and our system will submit your orders when the market opens.

Yes, this is supported where applicable for American-style options.

The value of your single-leg 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.
Please note that options strategies cannot currently be applied to some positions with their symbols or contract multipliers changed due to corporate actions such as a split or a merger.
If a position in an options strategy is subject to a corporate action, this will invalidate the options strategy and will most possibly result in an increased margin requirement too.

The majority of US stocks and ETFs have tradable options contracts.

Click on the icon located next to the buy/sell button on the order page to view the estimated margin, the commission cost and other important information.

Simply click on the button besides the "Trade" to pick the strategy then any one combination to see the details and submit the order. The default net price is set as the mark-price for convenience. Please set your own price.

Navigate to your portfolio, click 'Close' to close your combination order. In an event where a client wants to close a leg of an options contract that belongs to a specific combination order, a confirmation will serve to remind the client of possible change in margin requirements to place that order.

New positions could be matched with your existing holdings to form an options strategy that will lower our margin requirements.

If you liquidate part of your position in an options strategy that has a margin discount applied, the options strategy will be invalidated and the standard margin requirements will apply.

Consider liquidating the options positions you wrote in an options strategy first to avoid a possible increase in margin requirements calculated on your remaining positions, e.g. when the stock position you are liquidating in the options strategy is only partially filled.

Forced liquidation will occur when your account's securities segment's Excess Liquidity (EL) is less than 0.

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