  • Specific options with commodity-like behavior, such as VIX Index Options, have special spread rules and, consequently, may be required to meet higher margin requirements than a straightforward US equity option. Clients are urged to use the paper trading account to simulate an options spread in order to check the current margin on such spread.
  • If a combination of options is put on in such a way that a specific strategy is optimal at that point in time, the strategy may remain in place until the account is revalued even if it does not remain the optimal strategy. A revaluation will occur when there is a position change within that symbol. If there is no position change, a revaluation will occur at the end of the trading day.
  • Due to regulatory restrictions, Zacks Trade does not currently offer margin lending to natural persons who are residents of Australia.
