Option Strategy Margin
The margin requirements related to option strategy are as follows.
If your newly acquired options or stocks can constitute an options strategy with your existing positions, the margin requirements for the positions in your options strategy may be reduced. Margin reductions for options strategies at Tiger are based on their market risk levels, liquidity, options expiration dates, position conditions and other factors.
If you liquidate part of your position in an options strategy, the options strategy will be invalidated and if margin reduction was applied to that options strategy, such a reduction will also be invalidated, which will in turn result in a lowering of your account's securities segment's risk rate. Please ensure that you have sufficient funds for that segment (i.e. not futures segment) before liquidating a position in an options strategy as forced liquidation will occur when EL<0. *Excess Liquidity
If you need to liquidate part of your positions in the options strategy, we recommend that you consider liquidating the options positions in an options strategy first in order to avoid an increase in margin caused by your liquidation action. If you liquidate the stock positions in the options strategy first but only partially filled, it could cause the options strategy to lapse resulting in a higher margin requirement for the remaining options and stock positions than the margin requirement of the options strategy.
If you hold an options strategy that is approaching expiration, especially due to the risk of assignment of sold options, the amount of additional margin requirements for your options strategy will increase especially when the degree of an option sold being in-the-money increases as its expiration date approaches. If the assets in your account are insufficient to fulfil an assignment on the contract's last trading day, we may liquidate that contract anytime that day. It is recommended that you pay attention to the risks associated with approaching expiration.
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 such a corporate action, this will invalidate the options strategy and will most possibly result in an increased margin requirement too. Please ensure that you have sufficient funds in your account before liquidating your position in the option strategy as a forced liquidation may occur when EL<0.
Insufficient offset: For example, if have sold a call vertical or diagonal spread and the underlying’s price closes above the short strike but below the long strike, your short call will likely be assigned and your higher strike long call will not cover this assignment. When your short call is assigned, you'll be left with a short stock position. Similarly, if you have sold a call calendar or diagonal spread, but your long call is the short-dated leg, upon its expiry it will no longer exist to offset any subsequent assignment. These examples are not exhaustive and illustrate how option strategies may potentially result in losses greater than the theoretical max loss of a spread option strategy.
Important: To mitigate this risk, Tiger may close your position(s) prior to market close on an earlier expiration date. Ultimately, you are fully responsible for managing the risk within your account.
